Navigation Lights for Sailboats (And How To Read Them)

Last Updated by

Navigation lights on a sailboat can be confusing. If you understand the reason behind why they are the way they are however, they can make a lot more sense.

At their heart, sailboats are really just a power boat and as such must adhere to all power boat rules such as navigation lights. Other times however, a sailboat is classified in a special category. They have a set of additional lights they CAN show as an option, but are not always required to do so.

That’s about as clear as mud if you ask me and I contend that that is where the confusion about lighting a sailboat begins.

Just because you can show a light to identify yourself in times of low visibility, does not mean you have to and then we add in a little sibling rivalry between power and sail and things get downright adversarial when it comes to navigation and the night.

The USCG says You’re a Power Boat Whether You Like It or Not

Much to the consternation of many a sailor who has earned a commercial license to drive their sailboat, when you received your credential from the USCG it says you are a master of steam and power across the top with no mention of wind as a source of propulsion.

It is not until you read the back pages of your little red book that feels like a passport and looks like a US Sailing credential, that you will see the term “sail auxiliary”. That is because most of the time the U.S. Coast Guard knows that you are primarily reliant on your mechanical power to propel your vessel.

It's a sad thing, but the days of commercially viable sail boats are done and all but the most select few even have sails let alone use them as their primary power source. All sail boats by law are powerboats, but not all powerboats are sailboats.

Navigation Lights for a Power Boat

As a power boat, you are required to show certain lights and have been required to do so before power was even invented. 

In the days of man powered vessels like the viking ships who relied on oars while in close quarters to power their vessels, they needed to show other boats, friend or foe, where they were by showing lanterns in the dark to identify themselves. As you know, it is a time honored rule among all the nations of the world both past and present, that you must avoid a collision at all costs while at sea and even the viking knew that you should not run into things.

By lighting the front and back of your boat, you could warn other boats of your presence as well as identify which way you were heading. As such there is a very specific rule in the Code of Federal Regulations Number 46 (CFR46 by common name) that spells out with detail how many, the color, the luminosity or brightness, the angle of visibility and the location of all of the lights required for navigation on every single boat, seaplane, submarine and other nondescript vessel conceived by man to date that they must show while underway in reduced visibility.

And there is no flexibility in the rules.

As such a power boat, and by extension all sailboats, MUST, without question show one green light on the starboard bow and one red light on the port bow and one all around white light or lights while operating in reduced visibility. These lights should shine at all 360 degrees of visibility with the bow lights shining at an angle of dead ahead to 22.5 degrees abaft the beam and the stern lights shining 225 degrees dead aft. A forward facing masthead light that is white in color shall shine forward to comply with the directive that all vessels must carry an all around white light. For more read here .

As you can see, there isn’t much wiggle room when it comes to lights that must be shown.

Sailboats get a little flexibility with lights

Sailboats however, are a little different when they are in fact sailboats, which is only when you are entirely reliant on the wind for power and in no way reliant on any mechanical or manual means of propulsion. And for good reason.

Back in the day when men were men and sailboats were wooden, fire was a major concern. Sails were coated with wax and other flammable substances and the wood on boats was saturated with oils and grease. Even the ropes were plant materials saturated with oils to keep them pliable and strong.

Add those highly flammable substances to a parching environment like the sea and you had what was essentially a giant floating tinderbox.

Then tell that giant floating tinderbox that they need to identify themselves to the world at large at night using oil lamps with flames because batteries and lights were not invented yet. It didn't take very long or very many ships burning to the water line for the Governments to say to the sailboats, you get to do things a little different.

As such, sailboats are given special dispensation when it comes to lights aloft. They don't have to show an all around white light in their rigging because no one wanted to set their rig on fire with oil lamps 60 feet up in their rig.

However, when a sailboat takes their sails down such as when they are powered or at anchor, they must resume the display of an all around white light or lights aloft. That became a real challenge with aluminum masts and the disappearance of rat lines on the shrouds because there was no easy way to climb the rig and check the bulbs up the mast on a regular basis. 

Red over Green Sailing Machine

I have no idea where the history of this particular light comes from, but if you ever take a deck exam with the USCG, you better remember this mnemonic. An all around red light over an all around green may be displayed on a vessel during times of reduced visibility to indicate that a vessel is operating under sail power alone. 

I won’t even speculate on how or why they came up with this particular light configuration, but if you want to use these lights as a sailing vessel, you can do so, but that means that you will need three all round lights at the top of your mast, an all around white, an all around red and an all around green, just in that order.

The red over green is to be displayed in addition to the running lights or the red and green bow lights with the 225 degree stern light. As always, when the motor comes on, so does the steaming light or the forward facing white light that is also usually about ¾ of the way up on your mast to complete the requirement of an all around white light that indicates a power vessel.

What is a “steaming light” and why are you mentioning it now?

Most sailboat electrical panels will have a switch that is labelled “steaming light” and it will only come on when your anchor light is off. This is probably the most confusing part of sailboat navigation lights so if you are confused about this, you're in good company as most people are. 

A “steaming” light is named thusly, going back to the days of steam powered sailboats where when they fired up their boilers and doused the sails, they became a power boat once again. There aren’t too many steam powered boats, let alone steam powered sailboats, but the name stuck and it is a vestige of a bygone era.

Either way, when you fire up your motor, you turn on your “steaming light” and that locks out the all around white light which is used for anchoring to minimize the number of switches on your panel and reduce the number of wires in your mast. The fewer wires, the less chance of something not working or becoming disconnected.

The steaming light and the anchor light both go up the mast, but you can’t use an all around white light while using the 225 degree stern light at the deck level because to other boaters you would look like you have two white lights from the stern and that would be confusing.

The anchor light is used exclusively for anchoring while the steaming light is used to indicate you are a power vessel while underway.

As to why I am mentioning it now in the article, is because this would have blown your mind if I started with this subject cause it can be really confusing stuff.

Aspect Recognition with Lights

Remember when I said earlier that lights can help you tell others which way you are heading as well as tell you which way other boats are heading? That is called the aspect of the vessel and the USCG tests you on this for your deck exam as well. 

Knowing that the bow lights go 22.5 degrees abaft the beam on both sides or 112.5 degrees on each side, and the stern light faces 225 degrees aft for a total of 360 degrees of visibility, you can tell a lot about where a boat is heading and who has the right of way.

One thing that's easy to remember is red means stop and if you see a vessel's red light, it means stop as you are the give way vessel and approaching the other vessel from his port side. Conversely it works with green as well as that means you are approaching from the other vessel's starboard side and you are the standon vessel.

If you see a red and green light equally low on the horizon, that means your heading dead on into another vessel's path and conversely if all you see is a white light low on the horizon, it means you are overtaking another vessel power or sail, we don’t care because it is an overtaking situation. However, any time you do see a white light aloft in addition to the red and green bow lights, you know you are encountering a power boat.

Then there are angular approaches as well, where you see white and red or white and green light low on the horizon. You know in that case you are seeing a portion of the bow lights and stern lights from the side approaches of a vessel. Based on which direction those lights are heading, you can deduce which way that boat is going in relation to your boat.

So put it all together and you see a green light and a white light low on the horizon with a red over green light aloft, you know that you are approaching a sailboat that is traveling to your port and that might make you the standon vessel. That is of course, if we didn’t concern ourselves with windward and leeward and port tacks and starboard tacks, but that is a discussion for another article. So stay tuned when we talk about sailing rules and the right of way. But for now, do good, have fun and sail far.

Steaming Light on Sailboat: A Guide to Proper Usage

by Emma Sullivan | Aug 11, 2023 | Sailboat Maintenance

== Short answer: Steaming light on sailboat == A steaming light is a white navigation light fitted on the mast of a sailboat to provide visibility during low-visibility conditions. It is typically placed near the front side of the mast and angled downwards to indicate that the vessel is under power and moving forward. This light helps other boats identify and avoid collisions, ensuring safe navigation at night or in limited visibility situations.

Understanding the Purpose of a Steaming Light on a Sailboat: What You Need to Know

Have you ever been out on a sailboat and noticed a small light at the top of the mast? You might have wondered what its purpose is or why it’s necessary. Well, that little light is called a steaming light, and it plays a crucial role in ensuring safety and navigation on a sailboat . In this blog post, we will dive into the details of understanding the purpose of a steaming light on a sailboat.

To begin with, let’s clarify what exactly a steaming light is. A steaming light is a white-colored navigation light located on the front of the mast or near the bow of a sailboat. Its main function is to provide visibility to other vessels during low-light conditions or at night. This means that whether you’re sailing in foggy weather, dim lighting, or after sunset when natural visibility decreases, the steaming light will maximize your boat’s presence to prevent collisions with other boats.

So why is it specifically called a “steaming” light? The term “steaming” refers to sailing when using an engine rather than relying solely on wind power. When you are using your boat’s engine for propulsion instead of sailing with just your sails, it is known as “motoring” or “steaming.” The steaming light got its name because it primarily signifies that the vessel has powered propulsion engaged rather than utilizing only wind power.

Now that we know what a steaming light does and where it gets its name from let’s discuss more about its importance. One major reason for having this navigation aid onboard is compliance with international boating regulations and standards set by organizations like COLREGs (Convention on the International Regulations for Preventing Collisions at Sea). These regulations ensure safe navigation practices globally and require boats to display certain lights for visibility purposes both to avoid accidents and allow other captains to understand their intentions.

When operating under engine power, displaying only proper red (port) and green (starboard) sidelights can confuse other boaters, as these lights typically indicate the presence of a vessel under sail. To avoid such confusion, the use of a steaming light in conjunction with the appropriate sidelights clarifies that the boat is motoring and not just relying on its sails for propulsion.

Another important aspect to note about steaming lights is their distinct positioning on a sailboat . Typically, they are mounted at least one meter above the deck level to ensure maximum visibility. This height allows for unobstructed illumination, making it easier for other boaters to see your vessel from afar. It’s crucial to maintain this specific positioning to comply with regulations and maximize safety on the water.

In summary, understanding the purpose of a steaming light on a sailboat is essential for any sailor or boat owner. Its primary function is to provide visibility during low-light conditions or at night when using engine power instead of relying solely on wind power. By complying with international regulations and properly displaying navigation lights like a steaming light , you enhance safety by avoiding confusion between sailing and motoring vessels. So next time you’re out on the water after dusk or in foggy weather, remember the importance of that little but mighty steaming light atop your sailboat’s mast!

Step-by-Step Guide: How to Install a Steaming Light on Your Sailboat

Installing a steaming light on your sailboat might seem like a daunting task, but with the right guidance and a bit of patience, you’ll have it up and running in no time. In this step-by-step guide, we’ll walk you through the process of installing a steaming light on your sailboat, ensuring that you have a safe and well-lit vessel on your next sailing adventure.

You’ll need a steaming light fixture, wires (preferably marine-grade), heat shrink tubing, electrical connectors, wire cutters/strippers, crimping tool, electrical tape, screwdrivers (flathead and Phillips-head), mounting brackets or screws if needed, and a drill with appropriate bits.

Step 2: Identify the ideal location for installation Finding the right spot for your steaming light is crucial as it needs to be clearly visible from all angles while ensuring it won’t interfere with other equipment or rigging. Typically, sailors prefer placing it at the masthead or near where the mast meets the deck.

Step 3: Prepare for installation Ensure that all power sources are disconnected before beginning any work. Next, carefully remove any existing fixtures or wiring from the chosen location (if applicable). If there’s already an ample power supply nearby (e.g., an existing navigation light circuit), tap into it to minimize additional wire routing.

Step 4: Mount the steaming light fixture If your chosen spot requires mounting brackets or screws for support, position them accordingly using suitable hardware. Ensure they are firmly secured to prevent any movement due to vibrations caused by sailing conditions. Attach the steaming light fixture securely to these brackets using screws provided with the fixture.

Step 5: Connect wires and ensure proper wiring configuration Strip off some insulation from both ends of each wire to be connected. Using heat shrink tubing, slide it over one end of each wire to ensure a clean finish once the connections are made. Connect the appropriate wires from the steaming light fixture to the power supply or existing wiring and secure them using electrical connectors. It’s crucial to follow a proper wiring configuration, so refer to the manufacturer’s instructions or consult a professional if needed.

Step 6: Test functionality and safety Once all connections are securely made, reconnect the power source and turn on your sailboat’s battery. Switch on your steaming light and verify that it’s functioning correctly. Check for any loose connections, flickering lights, or signs of overheating during this testing phase. If everything looks good, proceed to finalize the installation.

Step 7: Secure and protect the wires Using zip ties or cable clamps, neatly bundle and secure all wires along their path towards the power source or existing wiring nearby. This step is especially important as it prevents any accidental snagging or damage caused by movement while sailing.

Step 8: Add finishing touches To ensure long-lasting durability and protection against environmental factors (moisture, saltwater), add an extra layer of weather-resistant insulation tape around exposed wiring connections. This additional safeguard will help shield your newly installed steaming light from any potential issues that may arise due to harsh maritime conditions.

By following these step-by-step instructions carefully, you can install a steaming light on your sailboat like a pro! Not only will you be adding an essential safety feature to illuminate your vessel in low visibility situations but also enhancing its overall aesthetics for impressive nighttime sailing adventures. So don’t let darkness dampen your enthusiasm – take charge of your boat’s illumination and enjoy safe sailing every time!

Don’t Set Sail Without It: The Importance of a Functional Steaming Light

When embarking on a sailing adventure, it’s crucial to ensure that every aspect of your vessel is in impeccable condition. From the sails to the rudder and everything in between, one essential component that often goes unnoticed is the steaming light. This small yet mighty fixture plays a significant role in ensuring both your safety and that of other sailors out on the water. In this blog post, we will explore why having a functional steaming light should never be overlooked when setting sail.

Firstly, let’s understand what a steaming light actually is. Mounted on top of the mast or at its front, the steaming light serves as an all-around white navigation light for boats under power. Its primary purpose is to help you stay visible to other vessels nearby by indicating your direction of travel at night or during periods of diminished visibility such as fog or heavy rain.

Now, you may be wondering why this seemingly inconspicuous light deserves so much attention. Well, think about it – imagine sailing through dense fog without a working steaming light! Without this beacon guiding your path, not only are you jeopardizing your own safety but also putting fellow seafarers at risk by refusing to comply with maritime regulations.

Additionally, navigating harbors and congested waterways becomes an even greater challenge without an operational steaming light. Picture yourself approaching a bustling marina late into the evening; by illuminating your boat’s foredeck with its bright white glow, the steaming light acts as a signal for others around you to be cautious and respect your right of way. This simple yet effective communication tool prevents accidental collisions and fosters harmony among boaters sharing busy waters.

But if safety isn’t reason enough to prioritize a fully functioning steaming light before each voyage, consider this: Mariners have an inherent responsibility to adhere to international maritime regulations set forth by bodies such as the International Maritime Organization (IMO). These regulations explicitly state that every vessel under power must display a white steaming light while underway during hours of darkness or limited visibility. By neglecting this requirement, you not only risk severe penalties but also jeopardize your reputation as a responsible boater.

Now that we understand the importance of a functional steaming light, it’s essential to keep it well-maintained and regularly inspected. After all, there’s nothing worse than setting sail only to have your navigation light fail at the most inopportune moment. Inspecting the wiring, replacing any worn-out bulbs, and ensuring proper alignment are simple steps that should form part of your pre-departure routine.

Remember, when it comes to sailing, “Don’t Set Sail Without It: The Importance of a Functional Steaming Light.” This unassuming yet crucial piece of equipment acts as both an indispensable safety feature and a responsible adherence to maritime regulations. So, before you embark on your next voyage, take the time to ensure that your steaming light is functioning optimally – after all, smooth seas start with being visible and considerate towards fellow sailors!

Please refer to the German Traffic Regulations for Navigable Maritime Waterways , §8 -10 and Preventing Collisions at Sea. Part C - Lights and Shapes. rules 20 - 31, and annexes I 1. - 14 for the exact wording.

NOTE: Vessels that are authorised to fly the German flag are generally only permitted to use approved navigation lights and sound signalling devices.

EU approval can be identified via the wheel mark symbol and the notified body number. BSH approved navigation lights (previously DHI) are marked with a model number (e.g., BSH/00/01/90).

However, even older lights with DHI approval that have already been installed maintain their approval, despite the changes made by the BSH.

In addition to the wheel mark symbol and German BSH approval, some lights are also approved by other countries, such as RINA (Registro Italiano Navale), MCA (Maritime and Coastguard Agency) and the USCG (United States Coast Guard). These are now recognised, provided the approval comes from the national approval body recognised in the country of origin.

National bodies whose accreditation is currently recognised in Germany:

The wheel mark symbol indicates approval of the Marine Equipment Directive (MED). This approval is valid for all EU member states, both for commercial vessels and recreational shipping.

0098 = Notified Body number (here 0098 = Germanischer Lloyd in Hamburg) 18 = year in which the mark is affixed, here 2018

• A CE mark is a symbol that must be affixed to a product by the manufacturer before it is sold on the European market. It indicates that the manufacturer is aware of the specific requirements for the product in question and that it fulfils the requirements of relevant European product directives. A CE mark does not supersede approval according to collision prevention regulations.
• Navigation lights are defined in detail by the International Maritime Organization (IMO), according to the International Regulations for Preventing Collisions at Sea, 1972 (COLREGs) Convention on the International Regulations for Preventing Collisions at Sea, 1972), in sections C and D. The following rules apply:

Which navigation lights are required on board according to IMO COL REG?

Definitions according to the 1972 International Regulations for Prevention of Collisions at Sea (COL REG 72):

1. Side lights for starboard and port

A green light on the starboard side and a red light on the port side, which shine from dead ahead in an arc of 112.5° aft to a point 22.5° abaft the beam (behind the beam) on either side of the vessel. On ships of less than 20 metres in length, the two individual sidelights may be replaced by a dual-colour combined light. This must be centrally located on the bow and stern axis.

2. Stern light

A white light mounted as close to the stern as possible and shines dead ahead in an arc of 135° (67.5° to each side). The mounting height should be aligned to the height of the side lights and should never be higher.

3. Three-colour light for sailing vessels (sailing lights)

On sail boats up to a length of 20 m, the side light and stern light can be combined into one three-colour light mounted on top of the mast. However, as soon as the sail boat's motor is engaged, the use of a three-colour light is no longer permitted. The rules for motor-powered vessels then apply.

4. Mast-head light

A white light placed over the centre line of the vessel and shines dead ahead in an arc of 225° (from straight ahead up to 22.5° more aft than crosswise to each side). The mounting height should be at least 1 m higher than the side lights. In the past, the mast-head light was also referred to as a steam boat light or steamer light, as it is only seen on ships that operate under engine power.

5. Signal light or all-round light

A light that shines in a complete circle of 360°. It may emit white, red or green light, depending on use. Examples of use: All sailboats and motorboats at anchor must exhibit a white anchor light . Ships over 12m in length must, if necessary, display vessel-in-distress lights (two red signal lights) placed at a vertical distance of at least 12 m. The distance between such lights must not exceed 1 m.

From what distance must navigation lights be visible?

The range indicates the distance from which the light can be seen. The minimum ranges of navigation lights are defined according to ship size as follows::

Best-seller Hella Marine

Note: When sailing boats are powered by a motor, the rules for motorboats apply and not for sailboats. The tricolour light may then no longer be displayed.

Displaying lights for sailboats up to 20 m

1 x red port side light

1 x green starboard light

1 x stern light

Also allowed:

1 x red all-round light on or near the mast top

1 x green all-round light on or near the mast top

1 x 3-colour light

Sailing vessels under 7 m (dinghies or small sports boats)

If, due to their design, no modern lights can be fitted, sailing vessels under 7 m in length and vessels being rowed must always carry an electric torch or lantern showing a white light, ready to exhibit in sufficient time to prevent a collision.

1 x Electric light or a torch with white light

Motorised vessels over 12 m

Lights used must be either / or:

1 x white masthead light fore

1 x dual colour light

Motorised vessels under 12 m

Alternatively, motorised vessels under 12 m can exhibit the following lights:

1 x white all-round light

Motorised vessels under 7 m and 7 knots maximum speed (small motor boats, dinghies or inflatables):

Motorised vehicles under 7 metres and with a maximum speed of no more than 7 knots can display the following navigation lights: all-round lights, portside and starboard lights.

The following applies in accordance with German Traffic Regulations for Navigable Maritime Waterways (SeeSchStrO): If, due to their design, no lights can be displayed (e.g., dinghies), sailing vessels under 7 m in length and 7 knots maximum speed must carry an electric hand-held spotlight or a torch to prevent collisions in the dark.

Left: 1 x white all-round light, 1 x red port side light, 1 x green starboard light

Right: 1 x hand-held spotlight or torch

Best-seller Aqua Signal Conventional

Best-seller Aqua Signal LED

Provided no engine power is used, the rules for sailboats apply. Motor-sailing vessels must display a large black cone pointing downwards when sailing during the day or at good light.

For vessels travelling under sail or at rudder during darkness or at reduced visibility, the rules for carrying lights for motorised boats automatically apply. This then depends on the length of the boat.

By day with a black cone, tip pointing downwards.

Torches % Spotlights

How must navigation lights be mounted on board?

Navigation lights must be securely mounted perpendicular to the waterline. Mast-head lights and stern lights should both be placed above the keel line.

At anchor during daylight? This must be displayed with a black anchor ball.

If the vessel is anchored outside of an area of water known by the River and Shipping Police Authority as an anchorage and berth for small vessels, this must be indicated as follows:

A black ball by day, 1 x white all-round light at night

Anchor Lights

If your boat is unable to manoeuvre*, this should be indicated as follows:

Stationary: 2 x red all-round light, 2 x black ball, one below the other (during the day)

Moving: 1 x red port side light, 1 x green starboard light, 1 x white stern light

* A vessel is described as if, due to exceptional circumstances (e.g., rudder failure or engine malfunction), it cannot manoeuvre as prescribed and therefore cannot avoid another vessel.

How do I indicate correctly that my sailboat or motorboat has run aground?

If your boat has run aground, this should be indicated as follows:

2 x red all-round light, 1 x white all-round light, 3 x black ball, one below the other (during the day)

Manufacturers that specialise in navigation lights such as Aqua Signal or Hella Marine supply a wide range of internationally approved navigation lights which work with conventional (with BSH bulb) or with permanently installed light-emitting semiconductor components (LEDs). The bulbs required for operation are an integral part of the approval. Replacement bulbs must also be certified so that approval / your insurance protection is guaranteed. Ships under 20 m: Stern and anchor lights require BSH-approved light bulbs with 10 watts, all other navigation lights 25 watts.

All series listed above with BAY15d sockets could alternatively be operated with a high-Power LED . The big advantage in doing so is that the LED is suitable for multiple voltages (10-30 V) and consumes just 3 watts during operation. Since the light colour, range of light or beam angle can vary depending on the housing, this light is NOT yet internationally approved.

Spare Bulbs - Conventional & LED

Energy consumption on sailing ships is, as ever, a topic of significant interest. This is especially true for blue-water sailors who like to sail longer distances at a stretch. The arguments for converting to LED technology are as follows:

• High energy savings due to the low power consumption
• Long lifespan (over 10,000 hours)
• MultivoltTM technology (10-30V) with greater tolerance to voltage peaks
• Compact and light housing constructions
• Waterproofed, hermetically sealed housings
• Maintenance free

When switching completely from conventional navigation lights to LED lights, lights with the BSH seal of approval / EU wheel mark meet all the requirements in terms of light colour (no risk of blue tint), range of light and beam angle, and that you are travelling in accordance with KVR.

Navigation lights with LED technology

Replacing your navigation lights is often easy to do as manufacturers usually use the same mounting points for LED lights or have an adapter plate for further use of existing drill holes:

Steaming light

• Robert Melotti
• January 5, 2010

The white, forward-showing light carried by a powered vessel by night or in bad visibility. In the Collision Regulations this is called a ‘Masthead Light’ (though not required to be carried at the masthead) and it must show from dead ahead to 22.5 degrees abaft the beam on each side. A vessel of less than fifty metres length may show one such light: those longer must show another similar light farther aft and higher up. A boat under sail does not show a forward white light.

CG regs for Steaming Light on 32 ft sailboat

• Add to quote

My 15 year old Hunter 326 does not have a steaming light but does have side and stern lights...as well as an anchor light. I am under the impression a sailboat this size does not require the steaming lite....previous owners obviously thought so too. Question is if I am under power at night should I use the anchor lite at the top of mast as a steaming lite?  

Did it have a "Steaming light" previously..?  

I'm no expert, but with the addition of the anchor light, you would be showing two white lights when viewed from astern. My 40 year old Bristol has a steaming light and I use it. Ken  

I believe, if the boat is under 12 meters (39ish feet) a single all around white light can be substituted for the forward facing masthead (steaming) and aft facing stern lights. If you think about it, when removing the forward and aft facing white lights, the all around is going to look the same from every angle.  

If you put in the query you will find that you are fine ! Regs require steaming on 20m and over !  

CarbonSink is correct. Being rather confusing to anyone overtaking you, I should think that puts the burden on you to make sure the overtaking vessel is not hampered. Rather a daunting thought, should that vessel be running at 15 to 20 knots, or more.  

You would simply extinguish the stern light, to avoid confusion. A stern light is not required, I believe, if you use an all around white light, for a boat of that size.  

Minnewaska said: You would simply extinguish the stern light.. Click to expand...

Your boat would have been built with running lights (sidelights and a sternlight) and a switched steaming light. Hunter often has a rocker switch - when set to power the steaming light is on, when set to sail it is off. Trying to use an an anchor light in place would be an all around bad idea. You would need to switch the stern light so you could turn it on when under sail, with the anchor light turned off.. Finally in close quarters in a crowded harbor, a running light located at the top of the mast is asking for trouble...it might meet a strict reading of the rules, but the insurance companies will give you 100% of fault just the same.

Interesting discussion. I would have bet money a masthead light (the term "steaming light" doesn't appear in ColRegs) was required on a boat that size, but as usual Minnewaska is correct that a vessel under 12 Meters (~39') can show an all around white plus side lights. I do believe the Regs require one or the other and that displaying an all around white at the masthead and a stern light would not be legal as it would create the impression of a head on situation with a large vessel (upper and lower masthead lights) with no side lights. If the boat was built to this reg, I would expect the stern light would be on its own switch to allow stern and sides under sail and all around white plus sides under power?  

I believe you have two choices Under Power: Under 12 meters and under 7 knots, you can show an all around white light. or You can display an all around white light and side-lights. ( with no stern-light) How you accomplish that with switching, is up to you.  

COLRegs specifies requirements that a vessel operator must meet, but it does not attempt to prohibit every possible dumb but conforming idea that a creative human might think of. No regulations limited to a few hundred pages can do that. Should the PO follow the woeful advice offered here, consider his discussion with his insurance company following the accident: Insurance: the other boat says they hit you because your stern light was out and they did not see you. PO: Sure, I turned the stern light off, but I had my anchor light on instead. Insurance: Why would you do that? PO: Because ColRegs doesn't say that I can't do it? Insurance: Are you kidding? You get the 100% fault. Remember accidents can involve more than just boat damage, people get injured also. Perhaps another thread on the question whether the PO's action in the described situation would qualify as willful negligence in a criminal case. See Fatal boat crash: Wrong man charged? | abc7news.com  

Insurance: the other boat says they hit you because your stern light was out and they did not see you. OP: Sure, I turned the stern light off, but I had my all-around white light on instead. I also had my sidelights on. Insurance: Why would you do that? OP: Because ColRegs Rule 23 (d)(i) reads as follows: "A power-driven vessel of less than 12 meters in length may in lieu of the lights prescribed in Rule 23(a) exhibit an all-round white light and sidelights." I was under power and my Hunter 326 is 32 feet in length, which is less than 12 meters. https://www.navcen.uscg.gov/?pageName=NavRulesAmalgamated#rule23 Edit: fixed cut and paste and added link  

If it were me, I'd have a Steaming Light installed. However, Steaming light, anchor light or stern light, not much is going to save someone from an idiot going 50 miles an hour up your butt.  

Understand that Hunter shipped the boat with an installed steaming light. The OP just needs to repair it, or install a replacement fixture it the OEM has been ripped from the mast. Sent from my SM-G965U using Tapatalk  

My understanding is that the masthead light with sidelights is legal. However, as some have said, I was never comfortable having the stern light off for fear of being hit from astern by someone not noticing the light at the top of the mast. My solution was a masthead light with separate fore and after sectors. At anchor, both on, steaming at night, only front on (with other nav lights unchanged).  

We, who sort of understand running lights and what they are supposed to symbolize (which puts us in the minority after dark, I'm pretty sure), are getting all wrapped around the axle about what is and isn't a 20-point white light showing forward when our sailboat is under power. I have, on small no-electricity sailboats when out after dark, used battery-powered red-green bow light combo forward, and a dive light with a taped-on "dome" made out of wax paper or other translucent stuff, and lashed onto the top of the tiller or rudder, as a sort-of stern light. When little outboard gets put into gear, I will typically add a similar jury-rig flashlight white light onto the mast, jammed under a tight spinny or jib halyard, as an "I'm under power" forward (steaming) light. None of these are visible three or five miles, more like a mile I would think. But it's something, I'm usually close to the harbor, and it's good practice. What's the point?? If I see just red and/or green, or both, somewhere ahead, I think "sailboat"! If I also see a white light higher up, but not atop Mount Everest, I think "powerboat"!! And if I see just a white light, I think "okay, some kind of boat, going away from me, or a small dinghy or whatever with a single white light. An anchor light way up on the masthead as a "steaming" light, at least at close quarters, looks weird to me. I wonder if it's a sailboat at anchor, or if I see red or green, if he's sailing and using the masthead light to see his telltales, or what? Or, is he anchored and forgot to kill the red/green? Or just confused about lights and figures "more is better"? It's easy to overthink, more so at night. True of more than just sailing ;-)  

I believe you are correct. We have a three way switch. Off; sailing w R/G and W stern light; steaming w R/G and all around masthead with stern light off. Of course, under 7 meters, we could be legal with a readily available lantern.  

Sail a lot at night. Nice to landfall the next island at daybreak. Also of course on passage. Something Capta said perks my interest. From the deck of my boat I can’t see another sailboats running lights once they’re a few miles off. If there’s a sea running they need to be even much closer. But if they have their masthead tricolor it’s rarely an issue. So coastal we use the deck lights but offshore the masthead. From what Capta says we may have this backwards. Now I figure ships will spot us on radar and AIS (if anyone’s looking) so issues of course and vog are moot. But rather the issue is small craft. A lot of cruisers may not have AIS or their radar may not be on. It’s them I want to see and want them to see me. Been with people who scan the 360o every 10 to 15minutes especially when offshore. Want to give them several chances to see me. I’ve had occasion to vhf call multiple times and finally get a response when doing a busy jump(Gorda-st.martin when it’s been awhile to get a window). We wanted to go to Marigot, they seemed to be heading for the Dutch side so we would cross. Finally saw a head peak out the companion way. He saw me then veered off for a bit allowing me to cross his bow without tacking or luffing until he passed which was gentlemanly. I was burdened being the overtaking vessel. We were both on port tack. Now his deck lights weren’t seen until we were close and even then were blinking. So think the tricolor may be safer overall in some circumstances.  

If you want to be seen by a particular nearby boat/tug/ship who's not that far away, a big bright flashlight shone onto your mainsail or jib and waved around, will be way more effective than any of your wonderfully correct running lights. Most vessel to vessel tangles at night are not caused by misapprehension of nav lights. Rather, it's by "*&%#, I never saw him"---/or/---" he never saw me"...  

Sidelights are red (port) and green (starboard) and shine from dead ahead to 112.5° aft on either side. Stern lights are white and shine aft and 67.5° forward on each side. (Thus, the sidelights and stern light create a full circle of light.) All-round lights are white and shine through 360°. Masthead lights are white and shine from 112.5° on the port side through dead ahead to 112.5° on the starboard side. They must be above the sidelights. Sailboats under power are considered powerboats. Sidelights may be combined into a single "bicolor" light. Powerboats less than 20m (65.7') in length need to show sidelights, a stern light and a masthead light. Power vessels less than 12m may show a single all-round light in lieu of the separate masthead and stern lights. Sailing vessels less than 20m in length need to show sidelights and a stern light. These may be combined into a bicolor light and stern light, or a single tricolor light at the top of the mast. Sailing vessels under 7m must have an electric torch or lantern available for collision avoidance. Oar-driven vessels can show either the sailboat lights, or use the electric torch/lantern option. When anchored outside a special anchorage, power and sail vessels under 20m must display an all-round light. Vessels under 7m are exempt, unless anchored in a narrow channel or anchorage, or where other vessels usually navigate. Sailboats with sails up during the day, but which are also under power, must fly a black "steaming cone," with its point downward, where it can be seen. When under power they must follow the rules of the road for powerboats. Notes Boats under power under 40' can substitute a single all-round light for separate stern and masthead lights Boats under 65'7" can substitute a single bi-color light for sidelights Sail boats under sail under 65'7" can substitute a tri-color light for separate sidelights and stern light. See our Anchor Ball Click to expand...

Keep a dive light in the cockpit to shine on the sails but mostly for checking trim. The shining on the sails bit is fine if you have nothing else to do and the other idiot is looking at your sail when you’re shing the light. I’m not going to be doing that for hours on end and often have other stuff to do. Nor am I going to wake someone up to do it. So don’t think that’s a practical answer except in certain limited circumstances. In the example above passed at least 1/2 dozen sailboats and was passed by another 1/2 dozen. Also several of those small tramps with the deployable ramps up front and two cruise ships. In those circumstances putting the spreader lights on briefly makes more sense. Light rules be damned become a fish boat for awhile and light up the world. Still like opinions on: When’s best to use your deck lights? When best to use the tricolor? BTW- get a steaming light. What’s legal and what’s wise are two different things. Same as what’s legal and what’s just.

I will add that the steaming light on the Hunter 36 that I used to teach on was at the very top of the mast, and shined through an arc of 225º. If one flicked on the anchor light, then the same fixture illuminated a 360º arc. I hated that setup because you couldn't see if either of these lights worked from the dock during daylight. I believe that the anchor light actually powered up two incandescent bulbs, thereby drawing twice the power when you were at anchor.  

This has been a rather... ...amazing "discussion". It's almost as bad as a stand on vs. law of tonnage discussion. Follow the rules or avoid the Salish Sea, please.  

I don't claim a ton of night sailing experience but the night experience I do have has been in the presence of a lot of other sailboats. For the most part I've witnessed deck level nav lights or masthead tri-color, properly displayed with judicious use of white light on the sails from time to time. I've also see a lot of dorked up stuff like sailing with the anchor light on presumably to illuminate a masthead fly. I've also seen careless handling of billion candlepower spotlights to illuminate telltales, but lighting up the cockpit of every other boat within 3/4's of a mile. In my experience the most difficult vessels to pick out nav lights I've ever encountered have been tugs and cruise ships that were displaying so many white lights on deck it took many minutes of observation with binos at night before being able to pick out the nav lights. In the case of the tug, I couldn't see the red or green until I was seeing both, fortunately at some distance and because he was changing course to exit the bay.

Not that it has too much to do with the discussion, but anytime I've been anchored in an area where I felt at all at risk of being run into at night, I would leave my foredeck and cockpit courtesy lights on in conjunction with the anchor light. Lit up the boat like a little floating city and made me worry a little less when woken up by the sounds of motors approaching.. LEDS are great...  

The " Rules" seem to have stood the test of time. 46 years, I believe that they're pretty well thought out.  

Your test of time is a test of enforcement, not law, morality, value or any other version of right and wrong. You can make smoking in a no smoking area a felony, if you have the enforcement.

Whats the Steam Light

• Thread starter Tom O'Callaghan
• Start date Jul 29, 2000
• Hunter Owner Forums
• Smaller Boats

Tom O'Callaghan

I have yet to figure out what the "Steam" switch on the electric panel does. It seems that all it does is light the mast light the same way the "Mast" switch (on the opposite side of the same toggle switch does. Can any one 'enlighten' me.thanks  

Steaming Light Tom,The 'Steam' switch on the panel is for the 'Steaming Light' on the mast. When a sailboat has it's engine on, whether or not the sails are up, it is considered a power boat for navigation rules. When underway at night with the engine on you have to light the 'Steaming Light' to indicate that.Dick  

Thomas Tongue

Anchor light Sounds like the "mast" position on your switch is the "all around/360" anchor light. But just like you, from the deck of my 26 I can't see the difference between the two. Perhaps if I were to skinny up the mast at night and look.......or maybe I'll be content with the assumption that the light is being thrown the right way!Tom/DFW  

mast/steaming lights The next time your mast is down, look at the light fixture on the top of the mast. The fixture has 2 lens and lights, the forward facing light is the steaming light(used whenever the motor is in use at night) in addition to the running lights. The rear facing light is the mast light. the mast light and the steaming light are used in combination to give a 360 degree anchor light. Hope that helps.  

Windvane I use the steaming light to illuminate my windvane at night. Anyone else?"Festivity" H26 1996  

Mike Pajewski

Steaming Light is required by the COLREGS The rules of the road (COLREGS) require a power boat to display a 225 degree white light at least 1 meter above the red & green running lights. When you are using your motor at night or in reduced visibility, you should turn the steaming and running lights on. Sailing vessels require no masthead light at all. This is how other boats can tell if you are a sail boat under sail or a power boat. This changes your right of way status. If you have the steaming light on and you are sailing, power boats do not have to give you the right of way.Mike PajewskiH26 "Loon"
