Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
309 words
A catamaran boat for use in combination with an engine-driven motorcycle which has a single ground-engaging drive wheel rotated by engine power and which has a single ground-engaging wheel movable on a substantially vertical axis for steering of the motorcycle, said boat comprisiNg: two spaced catamaran hulls and a deck attached to said hulls for providing buoyancy and stability to said boat and to the motorcycle mounted on said boat and to an operator of the motorcycle; a power roller and another roller mounted on said platform for engagement by the ground-engaging wheel of the motorcycle, first and second propellers mounted for rotation on axes extending generally longitudinally of said boat, one of said propellers being associated with each one of said hulls at the aft end thereof and positioned so that a substantial portion of said propellers is submerged when said boat is floating, drive means interconnecting said power roller and said propellers for rotating said propellers when said power roller is rotated; a turntable mounted on said platform for engagement by the steerable wheel on the motorcycle, a rudder mounted at the rear of each of said hulls on said boat respectively positioned aft of said propellers on said hulls and positioned to be substantially submerged when said boat is floating to steer said boat, the steering yoke secured to each side of said turntable and extending laterally therefrom in opposite directions, steering rods pivotally connected to the outer ends of said steering yoke, steering arms respectively secured to said udders and being attached to said steering rods so that rotation of said turntable causes rotation of both of said rudders in the same direction so that steering of the steerable wheel on the motorcycle causes rotation of said turntable and change in direction of said rudder for directing said boat as it moves through the water.
