Aquatic vehicle converter

An aquatic vehicle converter that employes a motor or engine powered multi-wheeled land vehicle to propel and steer a boat body, comprising:

• a boat body having two longitudinal hulls separated by a deck, and comprising propulsion and steering systems;
• a propulsion interfacing system that interfaces a driven wheel or wheels of the land vehicle with the propulsion system of the boat body, said propulsion interfacing system employing the rotation of the driven wheel or wheels of the land vehicle to rotate an output shaft in each hull that are used to power the propulsion system of the boat body, and wherein the propulsion interfacing system causes the rotational speed of the output shafts to be greater than the rotational speed of the driven wheel or wheels of the land vehicle by a prescribed speed factor;
• and
• a steering interfacing system that interfaces the wheel or wheels of the land vehicle used for steering with the steering system of the boat body, said steering interfacing system employing the rotation of the wheel or wheels of the land vehicle in the yaw direction that are used for steering to turn the aquatic vehicle converter using the steering system of the boat body.
