Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
176 words
A water recreational vehicle comprising: a floatable circular tube having a geometric centerpoint defining a center axis, a longitudinal axis, and a lateral axis, a rigid housing shell mounted on said tube, two hand controlled battery powered outboard motors mounted within said rigid housing and being symmetrically positioned on opposite sides of said centerpoint on said lateral axis, two oppositely facing seats mounted within said rigid housing and being symmetrically positioned on opposite sides of said centerpoint on said longitudinal axis, clamp means mounting said motors to said housing and permitting rotation of said motors about a vertical axis in either a clockwise or counterclockwise direction, a control means on each of said motors to permit selective control of the speed of said propellers and the direction of rotation of said propellers, said tube being free from protrusions on its outer perimeter to permit easy rotation thereof about said axis when in a floating condition by causing one propeller to rotate in a clockwise direction and causing the other propeller to rotate in a counterclockwise direction.
