4 Rudder Types for Sailboats
It is harder to move a full rudder than to move other types of rudders. Water flowing by the boat puts a great deal of pressure on a full keel rudder and makes the rudder hard to move. It takes a lot of force to push the rudder against the water moving past the boat. Spade rudders. Spade rudders are for fin keel boats rather than full keel boats.
Building a Faster Rudder
A boat with poorly trimmed sails and a crudely finished rudder will miss tacks and roll like a drunkard downwind when the waves are up. On the other hand, a rudder that is properly tuned will agilely swing the boat through tacks even in rough weather, and provide secure steering that helps prevents broaching when things get rolly.
Rudder Mods for Low-speed Docking
Sailboat rudders serve as both a control device for steering and lateral plane to develop lift. When sailing straight, or nearly so, the rudder operates at a relatively steady, low angle of attack. ... Finally, the narrow gap between the top of the rudder and the flat stern section of a racing sailboat effectively creates an endplate at the top ...

Making a Sailboat Rudder for an Offshore Yacht
This design of sailboat rudder is something of a compromise between the spade rudder and the full skeg rudder. Supported at its mid-point by a half-depth skeg, it benefits by the area forward of the stock, below the skeg. This applies a balancing force as the rudder is turned making the steering lighter than it would otherwise be.
Sailboat Rudders
Sailboat Rudders. The primary purpose of sailboat rudders is of course to give the helmsman the ability to steer the boat, but a well-designed one will also provide hydrodynamic lift to windward, in the same manner as does the keel. These twin high-aspect ratio rudders on an all-out race boat are clearly optimised for their hydrodynamic ...
Four Types of Rudders On Sailboats
The boat will rest safely on its side until the tide returns and lifts the boat off the shoal. Spade Rudder. The spade rudder rests below the transom separate from the keel.

Know Your Rudder
After hull integrity, rudder integrity is the most vital component of a seaworthy vessel, yet most sailors pay more attention to LED lighting or smartphone apps than they do to their boat's rudder.

What is a Sailboat Rudder?
A sailboat rudder steers the boat. A rudder is a hinged fin or blade mounted on the stern of the vessel that turns side to side, and it's controlled by a tiller or a helm.

Sailboat Keel Types: Illustrated Guide (Bilge, Fin, Full)
The most common sailboat keel types are full-length keels, fin keels, bulb keels, wing keels, bilge keels, and lifting keels. Full keels are popular among cruisers, while fin keels are generally used for racing. Bilge keels and lifting keels are typically used in tidal waters, on small fishing boats for example.
Docking a Dual Rudder Sailboat
Put the engine in reverse gear and apply a bit more throttle than you normally would on a single rudder boat. Keep the boat as straight in the slip as possible as you begin to back up. When the boat is 3/4 of the way out of the slip, turn the wheel to starboard, shift the engine into neutral gear and allow the boat to glide backwards into your ...
