Abstract: A vessel for carrying an RV (recreational vehicle) through the water, thereby effectively converting the RV to a houseboat. The barge-like vessel includes ramps for loading and unloading an RV at a boat ramp. The barge is powered by the drive wheels of the RV, wherein the drive wheels are each resting on two rotatable cylinders similar to a dynamometer cradle. The wheels spin the cylinders which in turn rotate the propellers so that the speed is controlled by the speed at which the drive wheels turn. Direction is controlled by a knob on a fly-by-wire type device which in turn controls the rudder. An alternative directional control includes two turntables onto which the front wheels rest. One of the turntables is mechanically connected to the rudder so that the steering wheel controls the rudder. Ballast tanks are provided at each side of the front and back of the barge to keep the barge level.

Abstract: An amphibious utility trailer to haul a load over land and/or to ferry a motorized vehicle over water. The trailer is adapted to receive marine propulsive power and/steering control from wheel torque and/or steering mechanism of a vehicle, such as an ATV. A propulsor such as a paddle wheel, propeller, or water jet propels the trailer through water when engaged with ATV wheel torque. A friction coupling such as a treadmill or set of rollers in the trailer bed removably interconnects the propulsor with ATV tires. The trailer may also include a rudder operable through a removable coupling with the ATV handlebars to steer the trailer in water. The arrangement enables the trailer to be “driven” over water utilizing the ATV and yet still provide a plain and simple utility trailer for hauling traditional items over land.
