  • Patent number: 4890570
    Abstract: A wind propelled sailing craft. The craft includes a frame with fore-and-aft beams interconnected by transverse beams. A deck is attached to the frame where the operator will sit on a trampoline. A sail-like structure is attached to the frame and extends upwardly from the deck. A pair of elongated hulls are disposed laterally of each other and include a pair of fore-and-aft spaced upwardly extending pedestals to pivotally receive one of the fore-and-aft beams of the frame. Each hull has attached at its tail end a rudder. A rudder bar is attached to and interconnects each of the hulls and the rudder attached to the opposite hull. A tiller is pivotally attached to the transverse beams of the frame and tie rods interconnect the hulls and the tiller. When the pilot moves the operator bar of the tiller, it acts to simultaneously move both hulls and both rudders to turn the craft.
