Many human powered boats have been developed, including designs with rigid hulls and paddle wheels or screw pro-pellers, bicycle-type frames on rigid and inflatable pontoons, and flotation wheels on a bicycle frame. Ultimately, a reclining bicycle frame mounted on hydrofoils, supplemented with pontoons and using an air screw propeller is the design that currently holds the human-powered speed record on water. This invention addresses the failings of a type of human powered boat which allows a conventional bicycle to be supported on and used to drive a collapsible boat. The entire boat can be stowed on the rack above the rear wheel. It has two inflatable pontoons and a light, collapsible frame. The rear wheel rides on a split roller which, through a series of miter gears, drives a screw propeller. The front wheel is connected to a hinging swivel which in turn is connected to the forward rudder and/or propeller housing. This invention allows the user to bicycle to a lake, inflate and assemble the boat, boat across the lake, disassemble and stow the boat and continue bicycling again. Additional features, such as a reverse drive, combined forward and rear steering, and hinging couplings on the forward rudder and rear drive assemblies to minimize damage from submerged logs are included in this invention. Finally, a series of performance boats with rigid hulls and with the same forward rudder and/or rear drive assemblies are shown. While this application is primarily about human powered boats, the configuration of a motorcycle is essentially the same as a bicycle. Many of the features disclosed could apply to a motorcycle boat, albeit necessarily stronger to support the additional weight of the motorcycle.
