Boat design is a compromise. so too is rudder design. if solar navigator is to glide through the water using minimal energy, her rudders should induce the least possible drag..

Forward rudders in the america's cup races of 1987 the american yacht usa featured (canard wings) a radical underwater design, where the two normal tasks of the keel (to lower the centre of gravity and to produce a side force), were split on different devices.. On a sailboat, as the rudder is moved to one side by means of the tiller or steering wheel, the force of the water striking one edge of the rudder turns the stern in the other direction to turn the boat. different types of rudders have different advantages and disadvantages. the type of rudder is often related to the boat’s type of keel.. For a traditional long keel sailboat with a full length keel, the rudder area should be equal to 0.068 x waterline length x draft. for a long keel sailboat where the keel is less than full length ; 0.058 x waterline length x draft..
