The different types of mooring systems and their uses

Understanding the different types of mooring systems and their uses is essential for ensuring the safety and security of your boat while exploring the open sea.

The Different Types of Mooring Systems and Their Uses

Sailing is an incredible way to explore the world, and one of the most important aspects of this lifestyle is understanding how to safely and securely anchor or moor your boat. In this article, we will delve into the various types of mooring systems available and their specific uses. Whether you are a seasoned sailor or just starting out, this comprehensive guide will provide valuable information to help you make informed decisions when it comes to anchoring and mooring your vessel.

A mooring system is a method of securing a boat to a fixed point, such as a buoy, pier, or the seabed. This is done to ensure the boat remains in a specific location and does not drift away due to wind, currents, or other external factors. Mooring systems are essential for the safety and security of your boat, as well as for the protection of the surrounding environment.

There are several different types of mooring systems, each with its own unique set of advantages and disadvantages. The type of mooring system you choose will depend on various factors, such as the size and type of your boat, the location and conditions of the mooring site, and your personal preferences and budget.

Types of Mooring Systems

Swing moorings are one of the most common types of mooring systems and are typically used in sheltered waters, such as harbors and bays. They consist of a heavy anchor or weight on the seabed, connected to a buoy on the surface by a chain or rope. The boat is then attached to the buoy using a bridle or mooring line.

The main advantage of swing moorings is that they allow the boat to swing around freely with the wind and tide, reducing the strain on the mooring system and the boat itself. However, this also means that a larger area is required for each mooring, as boats need sufficient space to swing without colliding with other vessels or obstacles.

Fore-and-aft moorings are similar to swing moorings but use two anchors or weights, one at the bow and one at the stern of the boat. This keeps the boat aligned with the current or wind, preventing it from swinging around and reducing the space required for each mooring.

This type of mooring system is particularly useful in narrow waterways or crowded anchorages, where space is limited. However, it can be more difficult to set up and maintain than a swing mooring, as it requires precise positioning of the anchors and regular adjustments to the mooring lines.

Pile moorings consist of two or more vertical posts or piles driven into the seabed, with the boat secured between them using lines or ropes. This type of mooring system is commonly used in rivers and estuaries, where the water depth and bottom conditions may not be suitable for traditional anchor-based moorings.

Pile moorings provide a secure and stable mooring solution, as the boat is held in place by the rigid piles rather than relying on the holding power of an anchor. However, they can be more expensive and time-consuming to install and maintain than other mooring systems, and may not be suitable for all types of boats or locations.

Marina berths are a popular mooring option for many sailors, offering a range of facilities and services in a secure and convenient location. A marina berth typically consists of a designated space within a marina, with the boat secured to a floating pontoon or fixed dock using lines or ropes.

Marina berths provide easy access to shore-based amenities, such as electricity, water, and waste disposal, as well as the added security of being within a managed and monitored environment. However, they can also be more expensive than other mooring options, particularly in popular or high-demand locations.

Mediterranean moorings, also known as Med moorings or stern-to moorings, are a common sight in the crowded harbors and marinas of the Mediterranean region. This type of mooring involves securing the stern of the boat to a dock or quay, with the bow anchored out in the water.

Mediterranean moorings are an efficient use of space, allowing more boats to be accommodated in a limited area. They also provide easy access to the shore, making it convenient for loading and unloading supplies or passengers. However, they can be more challenging to set up and maneuver, particularly for larger boats or those with limited maneuverability.

Mooring buoys are floating devices that are anchored to the seabed and used as a temporary or permanent mooring point for boats. They are typically made of durable materials, such as plastic or foam, and are designed to be highly visible and resistant to damage from the elements.

Mooring buoys can be a convenient and cost-effective alternative to traditional mooring systems, particularly in areas where the seabed is unsuitable for anchoring or where space is limited. However, they may not provide the same level of security or stability as other mooring options, and may be more susceptible to theft or vandalism.

When choosing a mooring system for your boat, there are several factors to consider, including:

• The size and type of your boat: Different mooring systems are better suited to different types of boats, so it’s important to choose a system that is appropriate for your vessel.
• The location and conditions of the mooring site: The depth, bottom conditions, and exposure to wind and waves will all influence the suitability of different mooring systems.
• Your budget: The cost of installing and maintaining a mooring system can vary widely, so it’s important to choose a system that fits within your budget.
• Your personal preferences and requirements: Some sailors prefer the convenience and security of a marina berth, while others may prefer the freedom and flexibility of a swing mooring or mooring buoy.

Regular maintenance is essential for ensuring the safety and longevity of your mooring system. This may include:

• Inspecting and replacing worn or damaged components, such as chains, ropes, and shackles
• Checking and adjusting the tension of mooring lines
• Cleaning and painting mooring buoys and other visible components to maintain their visibility and resistance to the elements
• Regularly diving on your mooring system to inspect the condition of the anchors, weights, and other underwater components

Anchoring and mooring are essential skills for any sailor, and understanding the different types of mooring systems and their uses is an important part of this. By choosing the right mooring system for your boat and location, and ensuring it is properly maintained, you can enjoy the freedom and fulfillment that comes from living the sailing lifestyle with confidence and peace of mind.

Complete guide to mooring systems.

Securing your vessel isn't merely a matter of anchoring it. Dock mooring types are crucial for any vessel owner or operator to keep ships safe from damage and well-anchored.

Haven Dock & Marine offers various mooring solutions that cater to different vessel sizes and environmental demands. 

Read on to learn about how various mooring systems and applications work to assist and keep boats, floating platforms, and other watercraft secure or stationary at all water depths.

What is Mooring?

A mooring type refers to a system made up of connectors, anchors, and mooring lines to keep a ship floating in deep water.

The variety of mooring caters to boat owners in different marine environments, ensuring your vessel stays put in calm lakes or faces the wrath of open seas. Mooring lines, mooring buoys, and more all play a part.

Selecting the Right Mooring Type for Your Needs

Maintaining your vessel’s safety starts with the right components for your mooring system, including mooring lines and mooring buoys. This will ensure your boat is secure, accessible, and safe from bumps and scratches. 

Dock mooring systems can support watercraft of all shapes and sizes, including:

• Cargo vessels
• Cruise ships
• Fishing boats
• Personal watercraft (PWCs or jet skis)
• Pontoon boats

There are two primary types of mooring systems: a shore fixture like a pier or an offshore fixture like a floating dock system . Regardless of the mooring system you choose, your dock or mooring point must be able to withstand a number of different forces, such as:

• The current
• Adverse weather

Your system's holding power should withstand any reasonable force your ship can expect to experience, whether small or large.

Mooring Equipment

Mooring line.

Mooring line connects to the anchor and keeps the structure afloat. Mooring lines are mainly made from wire, fiber rope, and chain.

Mooring Anchor

Your mooring system relies heavily on the strength of its anchor. The holding capacity of each anchor, which should generally be at least three times the weight of your service anchor, depends on the water depth, seafloor soil properties, and type of anchor you use.

Mooring Chain

The mooring chain connects the anchor to a floating buoy or watercraft. Experts recommend that your mooring line be three times the length of the water’s depth and a quarter inch thicker than your service chain.

It’s also a good idea to invest in mooring line supports to protect the line from chafing, as well as mooring whips, which are solid fiberglass rods that keep your watercraft a safe distance away from the dock edge to prevent damage during unfavorable weather conditions.

Although you can also choose from various mooring lines , cables, and ropes , stick with a chain for permanent moorings in waters up to 328 ft (100 m). For waters deeper than 984 ft (300 m), choose a stainless steel cable or wire rope. For ultradeep waters (more than 6,560 ft or 2,000 m), use a combination chain, wire, and synthetic fiber line for maximum strength.

Mooring Buoy

The mooring buoy, heavier than a standard buoy,  floats in the water away from the shoreline. The buoy allows boats to be moored in deep water instead of shallow water or to be moored to a pier.

Boat dock systems can use several types of anchors:

• Deadweight anchors use weight as their holding power to settle at the bottom of the sea and are the simplest type of anchor.
• Mushroom anchors look like an upside-down mushroom, are made of heavy cast iron, and are best for freshwater and smaller motorized water vehicles. If you get a mushroom anchor, find one coated with PVC to act as a bumper and prevent damage to your watercraft.
• Pyramid anchors are similar to mushrooms, except they’re shaped like a pyramid and become embedded in the seafloor quicker than the mushroom anchor. They’re used in shallow waters.
• Helix anchors consist of helically shaped stainless steel plates attached to a central shaft and use rotation during installation in the ground. They’re more eco-friendly and work best for marinas and residential systems in waters no greater than 60 feet.
• Piling anchors drive a single structure into the seafloor for maximum stability and minimal side-to-side movement.

Choosing Your Mooring: Types and Maintenance 

When setting up a mooring, think of it like planting a tree. It needs the right spot and some care to get started. 

Swing Mooring

This is a permanent fixture attached to the bed to provide stationary mooring. Swing moorings demand careful placement away from other anchors to avoid tangling. 

Pile Mooring

These are poles driven into the bottom of the waterway with their tops above the water. Boats tie mooring lines to two or four piles to secure their position between the piles. 

Pile moorings need precise installation but offer stability in crowded waters. 

Dockside Mooring

Dockside mooring involves securing the length of your boat to the dock using cleats and lines. Haven Dock & Marine offers a wide variety of cleats , from heavy-duty galvanized options to space-saving flip-up styles.

Maintenance

Regular inspections are essential. Look out for wear on lines and chains for swing and pile systems, or check that your dock bumpers stay firm and functional. This proactive approach will save you headaches down the line.

How to: moor a yacht alongside

• Bruce Jacobs
• September 6, 2020

Promotional feature in association with GJW Direct. Mooring a boat alongside securely will make manoeuvring easier, protect the boat in strong weather and give you peace of mind, says Rubicon 3’s Bruce Jacobs

When it comes to mooring your boat alongside, it helps to know which lines do what, what type of boat rope to use and how best to arrange them so that you can leave your boat confident that she won’t come to any harm. At the bow and stern, perpendicular to the pontoon are the two breast lines. These stop the boat moving out away from the pontoon. The two spring lines run fore and aft to stop the boat moving along the pontoon. They can be rigged from the bow and stern to a midships cleat on the pontoon, or from a midships cleat on the boat fore and aft to cleats on the pontoon.

BREAST LINES

The breast lines control how snug the bow or stern is to the pontoon, but don’t need to be overly tight, so the boat can move a little rather than snatching at its lines.

Breast lines hold the bow and stern in while springs stop the boat moving fore and aft

Whichever way you rig your springs, they will do the same job. If you need a bow or stern spring for manoeuvring , however, the springs will need to be rigged from the bow or stern, not midships. The longer the lines the better. Nylon rope has plenty of stretch to absorb the snatch loadings. If the springs are too short, or you use a low-stretch rope such as braid on braid or Dyneema, there won’t be enough give.

PONTOON CLEATS

Use a figure-of-eight on the cleat when you first come alongside. Once secure, swap it for a large bowline. If someone else is already using the cleat, pass your bowline up through theirs, then over the top of the cleat, so either of you can cast off without untying the other. For added security, drop an extra loop over the cleat, or pass it through the legs of the cleat and then over the top. You can also use a round turn and two half hitches, which is easier to untie under load.

ROPE ABOARD

Always keep the rope tail on the boat. With your bowline on the pontoon, pull the slack on board and tie off with a neat OXO (once round the cleat, a figure of eight, and round again). Never put a bowline or spliced loop on the boat’s cleats; an OXO is the only reliable method for letting go under load.

How to: service your lifejacket

Checking your lifejacket is in top condition should be done at least every season, says Bruce Jacobs

How to: check and change an anode

Promotional feature in association with GJW Direct. Keeping your anodes in good order prevents serious damage on board, says Rubicon…

How to: change a marine diesel water impeller

A well maintained impeller pump should prevent a failed impeller, says Bruce Jacobs of Rubicon 3

DOUBLING UP

In strong winds or if you’re leaving your boat, it is worth doubling up the lines. Ideally use two separate ropes to separate cleats, both on the pontoon and aboard, then if a cleat or rope gives way , you’ve got another to fall back on. Doubling up is different to rigging slips, where the working end of a mooring line goes round the pontoon cleat and back aboard the boat, which you will do before untying your bowlines when it is time to leave so lines can be handled aboard.

Mooring alongside, lines often go around sharp edges or over harbour walls and are liable to chafe. Keep a close eye on it and where there is any more than superficial wear, it’s time to replace the rope. The cost of new rope is worth it so the boat stays securely moored alongside.

GJW Direct offers some of the most comprehensive and competitive boat insurance policies on the market.  With more than 175 years in marine insurance, when you insure your yacht with us, you’re dealing with the boat insurance specialists, leaving you free to enjoy your time on the water.

• Mastering boat mooring: A comprehensive guide to tying up your boat

Mooring a boat is not just about tying a few knots; it's about keeping your vessel safe, secure, and protected. Whether you're at a marina, a dock, or out in the open water, having the right skills and knowledge for proper boat mooring is crucial for the well-being of your boat and those around it.

Why boat mooring is crucial

Boat mooring is essential for several reasons. It prevents your boat from drifting away due to wind, currents, or waves. It also ensures that your boat remains in place while you're not on board, reducing the risk of collisions and damage to other vessels and structures.

Essential tools for boat mooring

Dock lines are strong ropes used to secure your boat to a dock or another structure. They come in various lengths and materials, and their quality plays a significant role in ensuring a secure mooring.

Boat cleats

Boat cleats are fixtures on docks and boats designed to hold dock lines in place. Cleats come in different shapes and sizes, each with its specific purpose and strength.

Spring lines

Spring lines are particularly useful for keeping your boat from moving forward and backward while tied up. They run diagonally from your boat to a dock cleat, helping control lateral movement.

Types of knots for boat mooring

Cleat hitch.

The cleat hitch is a simple and effective knot used to secure a line to a cleat. It's easy to tie and untie, making it a favorite among boaters.

Bowline knot

The bowline knot creates a secure loop at the end of a line. It's useful for creating a non-slip loop around a cleat or piling.

Round turn and two half hitches

This knot involves wrapping the line around a cleat or post and then tying two half hitch knots to secure it. It's reliable for quick mooring.

Different techniques for mooring a boat

Side-to dock mooring.

In this technique, the boat is brought parallel to the dock, and lines are used to secure the boat's midship to the dock.

Med mooring

Med mooring involves mooring the boat perpendicular to the dock, typically with lines attached to the bow and stern.

Stern-to dock mooring

This technique involves backing the boat into a slip or space and securing the stern to the dock.

Step-by-step guide to proper boat mooring

• Approach the dock slowly and at a slight angle to counter wind and current.
• Prepare your dock lines and have them ready to secure.
• Use fenders to protect your boat and the dock from impact.
• Attach the first line to the boat cleat and then to the dock cleat using a suitable knot.
• Repeat the process with other lines, ensuring balanced tension.

Understanding docking lines and their role

Docking lines are your boat's lifelines while moored. They absorb shock, prevent jerking movements, and keep the boat secure against the dock.

Using spring lines for added security

Spring lines are set at an angle to control lateral movement. They prevent your boat from drifting away from the dock and are particularly useful in tight spaces.

Choosing the right cleats for your boat

Horn cleats.

Horn cleats have two upward-curving points, making them suitable for quickly securing lines.

Samson posts

Samson posts are vertical poles with a crossbeam. They provide a secure mooring point, especially for larger vessels.

Mushroom cleats

Mushroom cleats are shaped like, well, mushrooms. They are durable and provide a secure attachment point.

Common mistakes to avoid when mooring

• Failing to account for tide and current changes.
• Using improper knots that may come loose.
• Over-tightening lines, which can damage your boat and the dock.

Boat Mooring 101: How to Attach Your Boat to an Anchor or Buoy

• 1 Types of Moorings 
• 2 Preparing for Mooring 
• 3 Attaching the Boat to the Mooring 
• 4 Securing the Boat to the Mooring 
• 5 Disconnecting the Boat From the Mooring 
• 6 Conclusion

Are you planning to take your boat into the water for the first time? If so, then you must know how to attach it to an anchor or buoy properly. If you don’t, you might find yourself adrift and in danger if a storm should hit. Fortunately, with our Boat Mooring 101 guide, you’ll get helpful tips and advice on securing your boat to something solid.

We’ll start by discussing what boat mooring is and why it’s important. We’ll also look at the different types of anchors and buoys you can use and the parts of your boat you’ll need to attach them to. Finally, we’ll provide detailed instructions on how to attach your boat to an anchor or buoy in a safe, secure manner.

Types of Moorings 

There are two main types of moorings for boats: anchors and buoys. Anchors are heavy objects connected to the sea floor with a chain or mooring line , which is then attached to the boat. Conversely, buoys are large indentations in the sea floor that boats can tie off to with a mooring line.

Anchors are typically preferred when visiting a new location, as they provide better stability and can be moved as needed. However, anchoring in the same spot for extended periods is not recommended to avoid harming local wildlife and other boats. In addition, the choice of an anchor will depend on the type of bottom terrain in the area; a heavier anchor is needed for areas with thick sand or clay deposits.

Buoys are often used as permanent locations for boats at marinas, docks, or other regularly visited spots. They offer less stability than anchors but can still be suitable for short-term use with enough space. When tying up to a buoy, it’s important to check that there is enough room between boats for safety and to avoid causing damage to another vessel’s equipment or lines.

Preparing for Mooring 

Before attaching your boat to any type of mooring, it’s crucial to thoroughly inspect the area to ensure it’s safe and secure. Look out for rocks or debris that could pose a hazard while maneuvering, and avoid shallow waters or submerged objects that could damage your boat. It’s also important to check the mooring itself, whether an anchor or buoy, to ensure it’s properly secured and won’t move once your boat is attached.

During the inspection phase, watch for changes in weather conditions, such as strong winds or waves, which could make attaching your boat more challenging than usual.

If using an anchor, ensure it’s properly secured by pulling on the mooring line until there’s no movement felt in the anchor or line. For buoys, ensure they’re secured with multiple strong lines or mooring lines to prevent your vessel from drifting off in unexpected wind currents.

Attaching the Boat to the Mooring 

Attaching your boat to a mooring will vary depending on whether you’re using an anchor or a buoy and any specific instructions from local marinas or dock owners. In both cases, it’s important to secure one end of a rope (anchor) or both ends (buoy) onto your vessel before proceeding to prevent accidentally disconnecting from the mooring during attachment procedures.

To attach your boat to an anchor, first, find where the chain connecting it to your vessel starts and securely attach one end of a sturdy rope to this point. Next, lead the rope back towards either side of your boat’s stern, tie the other end firmly onto either side with several half hitches, and finish with one last secure knot at the top point where the two ends meet. This creates a loop shape similar to traditional knot-tying methods and will keep all parts tightly secured even during stronger currents.

When attaching your boat to a buoy, find two points near both sides of your stern where sturdy ropes can be securely attached. Lead those ropes towards either side of the buoy, securely tie them into small loops similar to traditional knot-tying methods, and finish with one large loop over all four ropes using half hitches. Make sure each point along these ropes has been securely tied with several smaller loops before progressing forward, and finish off with a tight knot at each connection point.

Always follow local instructions and be cautious when attaching your boat to a mooring to ensure a safe and secure experience out on the water.

Securing the Boat to the Mooring 

After properly securing all four ropes between your vessel and an anchor or buoy, it is important to ensure they are secured even further. This prevents built-in currents in the surrounding area from tugging at the ropes, causing the vessel to drift away unintentionally.

For anchors, it is essential to double-check all connections by visually measuring the amount of slack between each side. Then, you should tighten the bowlines around all four connection points equally while extending the outboard fenders away from both sides of each loop created by tying two separate bowlines around each connection point. This ensures that the ropes are held taut without slipping.

Extra caution should be applied for buoys, especially in congested waterways such as busy marinas. Use extra strong springs (mooring lines) directly connected around each loop created by combining both sides at the endpoint. This will prevent sudden swinging motions caused by strong winds. When dismounting, roll up the springs.

Disconnecting the Boat From the Mooring 

After making sure that everything is packed up and everyone is ashore, it’s time to disconnect the vessel from the moorings that have been set up earlier.

For anchoring, start by carefully loosening the bowlines, slowly releasing the tension that was put aside previously. It’s important to unwind slowly and check the entire circumference to ensure everything is properly disconnected. Then, gradually shorten the rope several times until it’s loose enough to be freely disconnected.

For buoying, it’s a bit more difficult, but still possible with the right knowledge. Disengaging involves larger loops underneath each respective loop created earlier, so they can be easily undone once released. After loosening, simply slip them free and let go. Then release the springs underneath them and revolve approximately, making the process faster than expected. Finally, reach the eventual desired objective and complete the process.

Mooring your boat is essential for safety and should never be overlooked. However, with the right knowledge and preparation, attaching your boat to an anchor or buoy is fairly straightforward. We hope this guide has helped you better understand how to attach your boat to an anchor or buoy and why it’s so important. Knowing how to moor your boat properly can help ensure your time on the water is safe and enjoyable.

Anchoring & Mooring

With so much investment literally riding on your anchor, your boat's anchoring system is no place to cut corners. your choice of anchor depends on the size and type of your boat, and the weather and anchoring conditions you generally encounter..

Boats with heavy displacements or superstructures that present a great deal of wind resistance need heavier gear. The same is true of cruising yachts that brave a wide variety of conditions and may sometimes have to anchor in open waters.

Although not required by Federal Law, it is recommended you carry one anchor of sufficient size and strength to hold your boat for an extended period, like overnight--or in an emergency situation, such as if you run out of gas. When you are thinking or buying an anchor - BIGGER IS BETTER.

Also, there is safety in numbers. No anchor will work for you in every situation, so if you have space carry two anchors--preferably of different types.Many people choose to carry a small anchor, or "lunch hook", and a larger working or storm anchor. The lunch hook is for use in calm weather and when the crew is monitoring the anchor. Working and storm anchors are useful at times when the crew is asleep or ashore, and during heavy weather, when winds are 30 miles an hour and over.

The general name for all of the equipment you need to anchor your boat is "ground tackle". This includes an anchor, chain, line and connecting elements. The anchor line, including chain, is called the rode.

Playing Hooky

Just as boats come in a wide variety of shapes and sizes, so do anchors. Choosing an anchor is easy, choosing the right one for your boat can be very difficult. Your first task in choosing an anchor is to have an understanding of three things:

• Your Boat - Your boats' size, weight and design characteristics affect what kind of anchor you will need to use. For instance, a 30 foot 10,000 pound houseboat needs a larger anchor than a 30 foot 6000 pound speedboat.
• Where You're Going - Where you plan to anchor often dictates what type of anchor you should use. Is the bottom rock, or is it soft mud? If you are not familiar with the area, ask around or look at a local chart.
• Local Conditions - Anchoring in a calm protected cove can be quite different than anchoring offshore or on a large open bay. And don't forget the weather--high winds, tides and waves can all make anchoring difficult, if not impossible.

Anchors are rated by "holding power"--which is the ability of an anchor to hold a given weight. Keep in mind that a 10,000 pound boat may only require an anchor with a holding power of a few hundred pounds on a calm day, but may need 1,000 pounds of holding power or more on a stormy day.

Anchor Types

There are several types of anchors and you should choose a style based on the bottom characteristics in the areas you will anchor most often. Then, choose a size based on the size and weight of your boat.

Lightweight or "Danforth" Anchors

Lightweight type anchor with two long pivoting "flukes"; designed to reduce clogging with mud and grass; range from 2.5 pounds to nearly 200 pounds, and are generally made of cast galvanized metal, though some models are machined from a light-weight aluminum composite. When dropped, flukes dig the anchor into the bottom and the anchor buries itself and part of the anchor line.

Commonly used on small recreational boats, as they are relatively light weight for the amount of holding power they provide, especially in comparison to other anchors. Best in hard sand or mud, where flukes can easily dig into the bottom.

Not recommended for very soft or loose mud, which can ball up around the flukes; or on rocky bottoms where the flukes cannot penetrate. Also not recommended for grassy bottoms, which the flukes tend to slip off.

Kedge or Navy Anchors

A more traditional style anchor with arks, flukes and stock. Good in heavy grass, weeds, rocky bottoms or hard sand where one arm can penetrate a crevice. Not good in mud or loose sand, where flukes can't dig in.

Functions differently than previous anchors as it is not a burying anchor; one arm digs into bottom and one lies exposed. Generally only used by very large ships, as it relies on weight for most of the holding power; not really suitable for recreational use other than for a lunch hook.

Grapnels Anchors

Very inexpensive, but not much holding power. Some models are made of bent re-bar, others are made of galvanized metal and have folding flukes. Good for recovering items on the bottom, or for wreck reef anchoring. Commonly used on very small boats such as canoes or jon boats.

Plow or "CQR/DELTA" Anchors

The plow styles' good holding power over a wide variety of bottom types makes it a top choice of cruising boaters. Has either a fixed (Delta style) or a pivoting (CQR) shank.

When dropped in the water, a plow lands on its side, then when pulled, buries itself. Its shape allows it to reset fairly easily should the wind or tide shift the boat position.

Great in sand and on rocky bottoms, weeds and grass. Does not do well in soft bottoms. Generally made of galvanized metal, though they are available in stainless steel.

Claw or "BRUCE" Anchors

Unique shape of the claw allows a 360 degree turn without breaking out. Has similar performance to plow anchors,at a lower weight.

Sets just like a plow, but curved flukes make it easier for a claw to right itself no matter how it lands on the bottom, or how much the boat gets swung around.

Mushroom Anchors

Mushroom anchors get their name from, as you might imagine, their rounded, mushroom shape. Mushroom anchors are used extensively for moorings, and can weigh several thousand pounds for this use.

The shape works best in soft bottoms, where it can create a suction that can be difficult to break. Decent for very small boats to use as a lunch hook, but not practical for larger boats. Both Buoys and Beacons may have lights attached, and may have a sound making device such as a gong, bell or horn. Both Buoys and Beacons may be called "marks".

Line and Gear

Depending upon the size and type of your boat, and where you anchor--your choices for an anchor line are either an all-rope anchor rode, a combination of rope and chain, or all chain.

Nylon Line in Three-Strand Twist

Three-strand line can absorb shock and the constant tugging associated with anchoring much better than braided line or chain alone. Chain may also be used, especially in anchorages that are primarily rock or coral, which may cut a nylon line. A length of chain should be used between the anchor and a longer length of line. The chain will add weight to set your anchor without making it too heavy to lift manually, while serving to exert a horizontal pull on the anchor to set it.

Nylon Three-Strand line is the leading choice for use as an anchoring line. Lines generally come in a "soft" or "medium" lie. Soft lines are generally softer to the touch, and loosely woven. These aren't as good as medium or hard lines for anchoring, as they are more prone to unraveling and chafing. Tightly wrapped lines are the best choice for anchoring.

Lines that have been treated with a wax-like coating are available. These lines help the line resist water/salt absorption. To help keep your lines in good shape, clean them from time to time by soaking them in soapy water. Never use bleach, as it can break down the line.

Chain may be used instead of nylon line for anchoring. Chain has several benefits, including added weight, chafe and wear resistance, and high strength. It also lowers the angle of pull on the anchor, which helps it to set more firn\mly into the bottom.

Chain is generally found made of galvanized steel, though you can find stainless steel and vinyl coated chain, which is designed to be non-marring to your deck.

Chain comes in three general varieties: "Proof Coil" is the most common, and is adequate for most marine uses. "BBB" ("Triple B" or "3B") chain has thicker, shorter links than proof chain. BBB is slightly stronger than proof chain, and is generally used for windlasses. Finally, "Hi-Test" chain is made of hardened steel, and is stronger and lighter than proof coil. Hi-test chain is favored by those wishing to avoid carrying too much weight.

Combination anchor-rodes consist of both chain and nylon line. You may buy a combination rode, or you may make one yourself. Generally, it is recommended to have either one foot of chain for each foot of boat length, or to have one pound of chain for each pound of anchor length. Which ever method you choose, having more chain than necessary is never a bad idea.

As the saying goes, a chain is only as strong as its' weakest link...Make sure that your anchor and line are attached to each other with adequate gear. Some lines come with plastic thimbles or eyes--but metal, either marine-grade stainless steel or hot-dipped galvanized steel, is best. Swivels and shackles should be inspected regularly for wear, and to ensure that the connections are tight and functional.

Scope: Length of the anchor line/ height of the deck cleat to the sea bed.

Before leaving the dock, you will need to determine how much anchor line, or "rode", you will need. It is recommended that you use a scope of 7:1, meaning that for every foot of water depth, you should use 7 feet of rode.

For example, to anchor in 10 feet of water, you would pay out 70 feet of line. Measure the scope as the ratio of the length of the anchor rode to the height of the bow above the bottom. If you're using a lightweight anchor on a small boat in good weather conditions, a shorter scope of 5:1 is sufficient and safe. A prudent boater always has extra line and chain on hand, just in case.

Minimum Working Rode Sizes

Suggested holding sizes assume fair holding ground, scope of at least 5:1 to 10:1, and moderate shelter from high seas.

Boats that operate generally in shallow waters, as on the East Coast of the United States, may get by with shorter rode lengths. As the wind picks up, deploying additional line will help maintain position, as will tossing out an extra anchor.

Setting Anchor

Anchoring can be accomplished quickly and easily by following a few simple steps.

• Check your chart for bottom characteristics and to determine that you are anchoring in a safe and allowable place. If there are rocks, shoals, reefs or other boats to consider, give them all as wide a berth as possible. Remember that other boats will often have different requirements for anchor rode length--larger or taller boats frequently need a great deal of rode. Also, keep in mind a possible swing of 360 degrees about the anchor with wind shifts or current changes.
• If your crew is not already wearing PFDs, have them put one on before going forward to set or retrieve an anchor or mooring.
• Secure the bitter end of the anchor line to a bow cleat. Make sure the line is ready to run free once tossed overboard.
• Head into the wind or current. Reduce speed and reverse the engine. When the boat starts to make a slight sternway through the water, lower - do not throw - the anchor.
• After you've let about a third of your line out, tug the anchor line to see how firmly it's set, and then continue to release the rode.
• Once you let out an appropriate amount of scope, make sure the line is properly tied off on the bow cleat.
• Even if anchoring only in designated anchoring areas, it is always prudent to have the appropriate signal such as an all-around white light on to notify other boats that you are anchored at night. During the day you must display a ball shape which is sized according to the size of your boat.

Staying Put

It's a good idea to take two immediate bearings. Select two items, one off each beam, that form a natural range and watch for any changes in their relationship. You can check these later to determine if you're boat is swinging as expected or if you're dragging anchor.

Picking Up a Mooring

One of the best ways to avoid the hassles of anchoring is to chose a cove or harbor with moorings available for your use. Mooring balls are identified by their white spherical or can shape, and having a blue horizontal band. It may have a number designation, a VHF contact # or name on it. You will typically have to pay a small fee to the harbor master to use a public mooring, but you can count on it being far cheaper than paying for dockage for the night.

Public moorings are professionally maintained and will use a large anchor or helix screw fixture to maintain position. The harbor master will let you know if the weight or length of your boat is too big for that particular mooring. Although moorings are typically more secure than anchors, moorings can and do periodically give way. For this reason, and for the obvious courtesy reasons, you should never pick up and use a mooring that does not belong to you.

Common Anchoring Mistakes

• Letting the anchor go with out securing the line to the boat.
• Letting the anchor go with your foot wrapped in the anchor line.
• Poor communication between the captain and person on the foredeck.
• Approach a mooring from downwind. This will give you better maneuverability as you go to secure your boat to the ball.
• Go slow, so as not to disturb those already moored.
• After putting on PFDs, send a crew member to the bow with a boat hook to grab the eye or the base of the mooring ball.
• Once the mooring ball is at the bow--slow, stop or gently reverse engines to halt forward motion. Use your crew to relay distance information if it is difficult for the skipper to see where the mooring ball is in relation to the boat.
• Loop the mooring line over one or both of your bow cleats. Pay attention to the possibility of chafing. You may want to use your own line to attach to the mooring ball if the one provided is dirty.
• Some moorings may have an antenna like device called 'whip.' This is simply an extension of the ball so you don't have to reach as far to haul in the mooring line.
• Once secure, let the boat drift back and be sure that you are clear of those who have moored or anchored around you. There is no need to 'back down' on a mooring ball.
• Leaving a mooring is easy--just motor or pull up gently to the ball and release the mooring line from your boat. You can then either drift back or maneuver forward to clear yourself of the ball and the associated ground tackle.

Finally, never ever anchor a small boat by the stern! Your engine, and the bulk of the boat's weight rest here. Stern anchoring is likely to result in swamping and flooding.

SECURING YOUR VESSEL: A GUIDE TO CHOOSING MOORING LINES

Mooring lines  are the unsung heroes of boating, silently ensuring your vessel stays safely secured when docked or anchored. But with an array of materials, thicknesses and lengths available, selecting the right ropes can be daunting. Here, we explain the crucial factors to consider when choosing mooring lines for your boat. 

Marlow Ropes has been the leading rope brand in the yachting industry for over fifty years, with a heritage in rope making going back over 200 years.

“Historically, we’ve found that mooring lines are the most over-looked ropes on any yacht. This is something we’ve always found baffling, especially when you consider that these are the most important ropes for securing your beloved boat. Sailors and boat owners often look at price first when buying mooring lines, which results in low quality, low durability and much shorter longevity.  “At Marlow, we manufacture a range of  mooring lines  to suit all budgets – each with their own unique specification to suit the requirements that we often come up against. It’s worth sailors and boat owners being aware of the unique construction characteristics of the various mooring lines on the market.”  Paul Honess, Leisure Marine Director

STRENGTH IS PARAMOUNT 

The primary function of mooring lines is to withstand the forces exerted on your boat by wind, waves, tides and currents. These forces translate to breaking strength, the amount of weight a line can hold before snapping. The key is to choose lines with a strength that significantly exceeds your boat’s weight. Consult your boat’s manual or manufacturer for its displacement (weight) and factor in a safety margin of at least 3:1. 

MATERIAL MATTERS

• Nylon:  Offers high elasticity, crucial for absorbing shock loads and preventing snapping. Bear in mind, it is known to degrade under UV exposure, resulting in reduced strength over time. 
• Polyester:  Known for its strength, and resistance to abrasion and sunlight. It has a lower stretch than nylon, so consider using mooring shock absorbers for additional give. This is the most reliable material for mooring lines.  
• Polypropylene:  A budget-friendly option with good buoyancy and moderate strength. Bear in mind, it stretches significantly and degrades quickly in sunlight. Only to be considered for its floating characteristics. 

MARLOW RECOMMENDS:   

3-strand Nylon  

Multi-plait Nylon  

3-strand Polyester  

3-strand Polyester Pre-stretched   for greater strength and durability 

Marina Grande  

Blue Ocean ®  Dockline   – sustainably manufactured from GRS certified rPET and available pre-spliced  

3-strand Nelson  

FINDING THE RIGHT SIZE

Mooring line diameter is directly linked to breaking strength. Use the breaking strength recommendations as a guide. Also, consider consulting a marine store professional for specific sizing based on your boat and typical mooring conditions. 

LENGTH MATTERS TOO

Mooring lines come in various lengths, with specific applications in mind: 

• Bow and stern lines:  These should be at least half the length of your boat, ideally longer, to allow for mooring at different angles and absorb wave action. 
• Spring lines:  Designed to prevent your boat from swinging excessively, these should be the entire length of your boat or even longer. 

The marine environment is harsh, so consider factors that can degrade your mooring lines: 

• Abrasion resistance:  Friction against docks, pilings and other boats can wear lines. So look for materials with good abrasion resistance or use chafe guards at potential wear points.  
• UV resistance:  Constant sunlight exposure weakens most mooring lines. So choose materials with good UV resistance or consider adding a UV protectant spray. Polyester is best, with nylon a reasonable second and polypropylene a distant third. UV stabilising techniques help, but don’t significantly alter the general comparable resistance values of each material. Counteracting UV deterioration should be a major consideration for yachts, especially in sunny climes such as in the Mediterranean and the Tropics. 

COMFORTABILITY CONSIDERATIONS

• Creaking  mooring lines is a bugbear for many sailors and boat owners plus those living or working close by. It’s often not known what causes the dreaded creak – but chafe, caused by salt water, or the fibre quality degrading over time may be factors. The addition of chafe covers or a lubricant coating may help. Nylon shrinks when it’s wet, which can result in a tightening of the rope strands, thus creating a harder, stiffer rope. This may lead to creaking, but a stiffer rope may be of greater benefit for permanent single purpose warps. 
• Handling  – Rope construction and diameter will make a difference to your comfort. Braided docklines, such as Marlow’s  Marina Grande  and  Blue Ocean® dockline , not only look good but feel good too thanks to their flexibility and smoother finish. This makes them much easier to handle, especially in the stressful situation when coming alongside.  
• Coiling and hanking  – For good rope maintenance, storing your mooring lines is vital to ensure their longevity and ease of use when it’s time to moor. A rope’s construction will dictate how it should be hanked. 3-strand ropes need to be rolled around your thumb to keep the lay in regular form. Whereas braided and plaited ropes should be formed into a figure of eight, to ensure twist is not imparted into the rope which puts undue pressure on to the fibres.   

INSPECT YOUR ENVIRONMENT

Mooring lines are a safety-critical element. Regularly inspecting them for signs of wear is good practice – replace them promptly when they show signs of deterioration. When in doubt, consult your local rigger or chandler for recommendations specific to your boat and mooring conditions.  

By making informed choices, you can ensure your boat stays securely moored, giving you peace of mind while you’re off enjoying the water.

Mooring Clearance

Anchoring clearance, standing rigging clearance, running rigging clearance, deck hardware clearance, chandlery clearance, safety clearance, the main factors to consider in selecting your mooring rope.

Stretch Factor – mooring lines need to absorb snatch loads and maintain the capacity to elongate and recover without suffering premature stress failure. Polyester has the required amount of working stretch for mooring and the ability to absorb surge loads can be enhanced with mooring compensators. Polypropylene stretches a little more than polyester. Nylon is the most elastic of the three materials, approximately 5-10% more elongation than polyester.

Strength and Durability – mooring ropes need to manage the substantial strain experienced in securing a yacht in your chosen configuration (the number of ropes that effectively divide the load) so relative diameter and break load are important factors. Nylon is initially the strongest mooring rope but it is a widely held belief that it loses 10-15% when thoroughly wet which brings it back to relative parity with polyester. Polyester has better UV resistance than nylon which means that it builds a small advantage each season resulting in a longer working life. Polypropylene is not comparable to the other two materials and should not be considered unless stepping up in diameter.

Abrasion Resistance – depends on what the rope is made from, how it is manufactured and to a lesser extent, the finished construction. Polyester and Nylon have comparable performance with Polypropylene, again a distant third. LIROS employ heat setting technology and special twisting techniques on the fundamental filaments and yarns to enhance wear performance.

Nylon shrinks when it is wet resulting in a tightening of the rope strands creating a harder, stiffer rope. This can be of benefit for permanent single purpose warps.

Comfort – rope construction and diameter make a difference to comfort, especially for more delicate hands. Braided Docklines are commonly regarded as the most flexible, luxurious handling rope for mooring. Octo (Anchor) plaited ropes are also flexible and comfortable to handle. 3 strand rope is generally regarded as less kind to the hands but is probably still the best all-round choice for most mooring applications.

Handling, Coiling and Hanking - rope construction dictates how you should hank a rope into a coil for stowing and throwing/heaving. 3 strand rope needs to be rolled around your thumb to keep the lay in regular form. Braided and Plaited ropes should be allowed to form a figure of eight shape, to ensure that you are not imparting twist into the rope.

UV Resistance – Everything degrades in the sun. The speed at which the deterioration occurs depends on what the rope is manufactured from. Polyester is best, with nylon a reasonable second and polypropylene a distant third. UV stabilising techniques help but don’t significantly alter the general comparable resistance values of each substance. Counteracting UV deterioration should be a major consideration for yachts in the Mediterranean and the Tropics.

Buoyancy - Polyester and Nylon both sink. Polyester is slightly heavier than nylon. Polypropylene floats. There are some applications where it is important that a line floats on the surface, but otherwise Polyester and Nylon are more durable fibres in terms of strength and resistance to abrasion and UV.

Summary - Polyester is the best all round fibre for mooring applications. Nylon has additional elasticity and can develop a harder finish which is of benefit for certain solutions. Polypropylene isn't really comparable and should only be selected to take advantage of the fact that it floats.

Single Purpose Mooring Lines

Single Purpose Mooring Lines are ropes made up to a specific measurement, spliced and finished to fit your home berth mooring configuration. These lines tend to be for more permanent arrangements, also known as Permanent Warps:

Mooring Strops and Mooring Bridles

Design Considerations and Plus Factors:

• You can select your preferred optimum rope for each purpose: base material (rope type), construction, diameter and exact length.
• Spliced loops to conveniently drop over cleats or bollards, remember to allow just enough extra to pull the loop to the furthest extremity of the horn, before it drops over and sits neatly around the cleat base. Spliced loops can be ordered with anti-chafe webbing fitted.
• Spliced thimble eyes for connecting shackles to rings, or other fixed attachments on the pontoon or harbour wall. Stainless steel connections reduce the chances of abrasion.
• Mooring Compensators threaded onto the lines before splicing, to add extra shock absorption where it’s most needed.
• Chafe Protection threaded onto the lines before splicing, to protect the most likely wear points.

Multi-Purpose Mooring Lines

Multi-Purpose Mooring Lines are generally longer lengths that can be deployed for varied tasks and tend to be for more temporary arrangements.

• You can select one rope type suitable for all your mooring requirements. This may help the crew to become more proficient at critical moments.
• Spliced loops on one end can be very helpful when trying to secure your yacht in difficult wind and tide conditions.
• All non-spliced rope ends should be heat sealed and whipped to prevent fraying.
• Bow and Stern lines can be made off and doubled back to make a spring.
• Longer lines can be deployed to attach directly to the pontoon, when your yacht is outside several others on a visitors pontoon.

Rafting Out and Towing Warps

It’s generally good practice to have two long lines in your rope inventory for when you’re rafted out on a visitor pontoon. It is not advisable or the done thing to rely on your inner neighbours to keep you securely moored to the jetty, by simply tying up to next door’s cleats. You will create extra load on their lines and fittings which will not be appreciated and in any case, may expose their lack of strength and suitability.

It’s also a good idea to consider a towing line for emergencies. Stowage room and extra cost may lead you to designate an existing mooring or anchoring warp for this purpose. Just bear in mind that the rope ends need to be finished in a versatile manner so that the line is genuinely multi-functional. A towing warp needs to be long and fairly stretchy so is reasonably compatible with doubling up as rafting out, kedge or drogue warps.

Compare the three main choices of Mooring Rope Construction:

3 strand also known as twisted lay .

The most popular all-round choice ~ optimum choice on all counts except for handling where it's not quite as comfortable as braided or plaited lines - and the least expensive of the three options.

Anchorplait, Octoplait 8 Strand

More commonly used for anchoring warp but has all the required properties for mooring, a little more comfortable to handle than 3 strand and on a par with Braided Docklines in terms of cost ~ 12 plait hollowbraid is available at a lower price point.

Braided Dockline

The most comfortable handling with all the benefits of polyester fibre, specially twisted filament yarn for optimum endurance.

The 6 Best Dock Lines (and Boat Springs) for Securing Vessels

MaOne of the most essential elements of any boat is the quality of the dock lines . They stop your prized possession from drifting away from the jetty and into the great beyond.

A good dock line will keep your vessel secure in all weathers and will last no matter what the elements have to throw at them.

So, if you're looking to upgrade your dock lines or are simply trying to make the right choice, look no further and read this article to get the lowdown on the best dock and mooring lines for boats.

How to Choose the Best Dock Line for Your Boat

Choosing the right dock line comes down to four elements: the size of your boat, the thickness of the rope, the length of the rope and the configuration you use when docking.

Once you've established these four things, you can be sure that you have chosen the best dock line for your boat.

Boat Size vs. Rope Thickness

The general rule of thumb for choosing the best size mooring line is roughly 1/8 of an inch in diameter for every 9 feet of length . For smaller craft, this is an easy decision.

There aren't any rules that state you can't have a dock line that's twice the required thickness. After all, whatever happens, it isn't going to snap.

In relation to rope thickness, here's a basic rule of length and weight to consider:

• Boats 19.5 - 33 feet - 2,200 - 20K pounds | 10 - 14 mm thick
• Boats 39.5 - 59 feet - 28 - 55K pounds | 16 - 20 mm thick
• Boats over 59 feet - 55K pounds | 24 mm thick

How Long Should My Dock Line Be?

It's generally accepted that you should keep four lines on your boat : two the same length as your boat and two lines at 2/3s the length of your boat.

For example, if you have a 26-foot vessel, you should have two 26-foot dock lines and another two at roughly 17 feet in length.

Let's Talk Dock Line Configurations and Springs

There are many ways to configure your dock lines to secure your craft and spread the load apportioned to each rope. But here I'll share the most common.

Referred to as springs, they act as a damper to a boat's forward and backward motion as it moves against waves or passing vessels. A good spring enables the load placed on the dock line to spread the weight and movement, preventing the boat from clattering violently back and forth or hitting the dock sides.

Take a look at the several springs you could deploy:

• After Quarter Spring - This is where the dock line is fed from the stern of the boat, in an outward direction away from the vessel at roughly 45 degrees.
• Quarter Breast   Spring  - These lines run at right angles to the dock cleats.
• Forward Quarter Spring  - This is where a dock line is fed from the stern and secured to a cleat located in the center of the pontoon. Again, the rope is at a 45-degree angle.
• After Bow Spring  - This is the reverse of the Forward Quarter Spring, with the dock line reaching from the bow at 45 degrees, and meeting in the center of the vessel.
• Forward Breast Spring  - This is the same as the Quarter Breast Spring but tied from the bow of the boat at a right angle.
• Forward Spring  - A rope is tied at a 45-degree angle, heading away from the boat.

Springs are important, but you wouldn't want to employ all of these at the same time. Not only would it be time-consuming, but it would also be completely pointless and considered overkill.

You should tie one at the bow and stern, and then use a Quarter Spring both fore and aft.

The Important Cleat Hitch

The cleat hitch is widely accepted as the best knot to secure your boat to a jetty or mooring where there are cleats . It's one of the easiest knots to tie, but far from simple if you want to get it right. Done properly, it would take a minor disaster for your vessel to become unhitched.

Pass the line entirely around the base of the cleat under the horns. Then, make a figure-eight over the left and right horn. To secure, turn the rope under itself to make a half hitch.

You should not require any further winding or looping as it does nothing to improve the effectiveness of the knot. In fact, should you need to cast off in an emergency, you run the risk of making it harder to unhitch with over-complicated twists. Just leave it as it is in its own simple and elegant state.

Best Rope Material

• Nylon  - This is by far the best choice for dock line as it's relatively cheap compared to other types, is elastic enough to absorb the weight and movement of your boat and is UV resistant. All in all, if you want excellent shock absorbency, choose nylon.
• Polypropylene  - This dock line is the cheapest of them all, and it shows. It does have attributes. It floats, for one thing, making it ideal should you need to retrieve it from the water. It does offer some UV resistance. However, it doesn't last as long as nylon and lacks the elasticity needed to absorb all that movement. Polypropylene is a great alternative if you're looking for the cheapest option, but it could be a false economy.

The 6 Best Dock Lines for Securing Vessels

It comes as no surprise that the best dock and mooring lines I have featured are all nylon, given its popularity and reasonable cost. It's also the material I prefer for my dock lines.

Through this list, I'll demonstrate that nylon dock lines don't have to break the bank. Although more expensive varieties are available, I have divided the ropes into budget and premium sections.

Editor's Choice

  Check Price on Amazon - Made of marine-grade double-braided nylon, Better Boat Dock Lines have a working load of 950 lbs and a b reaking strength of 4,939 lbs.

These 1/2 inch dock lines are 25 feet long and have a 12-inch heat-treated eyelet at the end. Superior shock absorption and elasticity keep boats secure in high winds and rough waters. You can even use it to hang boat fenders  or for tent tie-downs while camping.

This dock line falls nicely between a budget and premium dock line in price, so it's really a win/win as far as quality, price, strength and durability go. 

• Material: Nylon
• Thickness Range: 1/2 inch
• Length Range: 25 ft

Runner Up Dock Lines

Shoreline Double-Braided Nylon Dock Line

Check price on Amazon Shoreline dock lines are available in four colors: black, blue, gold and white. Without kinking or rotating under pressure, they have a dedicated loop on one end and a straight end on the other. This lets you decide what configuration you want to use when tying the boat to the dock.

Soft to the touch, these lines won't rub or scrape your boat. And because they're double-braided Nylon, they're super-strong with a load capacity of 1,140 pounds and a tensile breaking load of 5,700 pounds . That's enough to weather heavy conditions .

• Material : Nylon
• Thickness Range : 1/2 - 3/8 in
• Length Range : 15 - 25 ft

Crown Sporting Goods Double-Braided Dock Line

These Crown lines are available in black, blue, red and white, making them easily visible as they match your vessel's color combinations.

The double-braided Nylon construction can withstand load pressures of up 3,200 pounds and is also UV, abrasion and mildew resistant .

I like this rope, especially for docking smaller craft .

• Thickness Range : 3/8 in
• Length Range : 25 ft

Premium Dock Lines

SeaSense Double-Braided Dock Line

This SeaSense dock line is intended for use with vessels that are at the lighter end of the spectrum (think: dinghy or small fishing boat). It has a 410-pound load capacity with a breaking strength of 3,900 pounds .

The eyelet is 10 inches in diameter. T his rope offers the elasticity that all good nylon ropes should have.

It comes in black, blue and a gold sheened white, making the springs and lines easily visible in poor conditions .

Because it's inexpensive compared to other lines, it may be the ideal choice for beginner boaters .

• Length : 15 - 25 ft

Norestar Double-Braided Dock Line

Norestar lines are extremely robust and have a high breaking strength. The 1/2-inch diameter rope has a breaking load pressure of 8,300 pounds , while the 3/4-inch thickness has a tensile load capacity of 19,100 pounds . That means it will hold a vessel of over 18,000 pounds!  

These dock lines are also abrasion-proof and UV resistant, so they should withstand the elements. 

• Length Range : 15 - 50 ft

Final Thoughts

Never underestimate the importance of a good quality dock line . It's one of the most important tools any boater can have.

Choose a cheap dock line at your peril, especially if you leave your boat docked for the winter when the weather is at its worst.

In addition, consider the boat docking or mooring line's best working capacity, maximum breaking strength and shock-absorbing qualities.

Once you have all this checked, make sure that you remember the rule about 1/8th of an inch in diameter for every 9 feet of boat length , and you won't go wrong.
