Abstract
A sailboat hull comprised of a monolithic structure fabricated of low-density polymer foam and having integrally formed therewith an internal H-shaped structure. The H-shaped structure serves to reinforce the hull and provides buoyancy chambers extending along either side of the hull and a centerboard trunk medially of the hull. The chambers define leg space therebetween and are so proportioned that said leg space is buoyantly supported above the surface of the water when the hull is in a tipped vertically disposed position. The hull is provided with a rudder comprised of a pair of separate cheek plates vertically disposed in spaced parallel relationship to one another and held in this position by extruded aluminum pintle blocks secured between the plates. The pintle blocks extend forwardly of the plates and carry aligned pintle pins. A tiller is fixedly attached between the upper edges of the plates and the rudder is pivotally secured between the plates beneath the tiller.
