Amphibious utility trailer that receives marine propulsive power and/or steering control from a ferried vehicle

A land-towable amphibious utility trailer operative to generate marine propulsion from an ATV having at least one drive wheel, said utility trailer having front and rear ends respectively serving as a bow and stern when propelled over water and being adapted to enable land-loading said ATV while attached to a towing vehicle and back-down water launching of said trailer/ATV while attached to said towing vehicle, said utility trailer comprising:

• a frame defining said front and rear ends,
• a tongue affixed to the front end of said frame to enable land-towing of said trailer and back-down water-launching of said trailer while attached to said towing vehicle,
• a substantially flat and unobstructed deck mounted on a top of said frame,
• a barrier extending around a periphery of said deck that includes a ramp segment near said rear end of said frame to enable said ATV to drive-on and drive-off said trailer while attached to said towing vehicle,
• an axel mounted on an underside of said frame for carrying a pair of wheels, each being positioned on a respective side of said frame,
• a floatation system to provide buoyancy in water, said floatation system including a series of individual buoyancy segments mounted on the underside of said frame,
• a propulsor to propel the trailer through water in response to torque applied thereto, and
• a drive coupling to removably couple wheel torque of a drive wheel of the ATV with the propulsor when the ATV is positioned on said trailer.

A land-towable amphibious utility trailer operative to produce marine propulsion and to provide steering capability from an ATV, said ATV having at least one drive wheel and at least one steerable wheel, said utility trailer being adapted to enable ATV drive-on and drive-off while attached to a towing vehicle and back-down water-launching of said trailer while still attached to said towing vehicle, said utility trailer comprising:

• a frame having a front end and rear end respectively define a bow and a stern,
• a tongue affixed to the front end of said frame to enable land-towing of said trailer,
• a substantially flat and unobstructed deck mounted on a top of said frame,
• a barrier extending around a periphery of said deck that includes a walk-off gate near said front end to enable personnel ingress/egress during back-down water-launching of said trailer while attached to said towing vehicle and a ramp segment near the rear end of said frame to enable ATV drive-on from land while attached to said towing vehicle,
• an axel mounted on an underside of said frame for carrying a pair of wheels, each being positioned on a respective side of said frame,
• a floatation system to provide buoyancy in water, said floatation system including a series of individual buoyancy segments mounted on the underside of said frame,
• a propulsor to propel said trailer through water in response to torque applied thereto,
• a drive coupling to removably couple wheel torque of an ATV drive wheel with the propulsor when positioning the ATV on the trailer,
• a steering mechanism to steer the trailer in water, and
• a steering coupling to removably couple a steerable wheel of the ATV with the steering mechanism in order to steer the trailer using a steerable wheel of the ATV.

An amphibious utility trailer adapted for marine propulsion by an ATV having drive wheels, said utility trailer being adapted to enable ATV drive-on and drive-off while attached to a towing vehicle and back-down water-launching of said trailer while still attached to said towing vehicle, said utility trailer comprising:

• a frame defining a front end and a rear end that respectively serve as a bow and stern when underway over water,
• a tongue affixed to the front end of said frame to enable land-towing and back-down water-launching of said trailer,
• a substantially flat and unobstructed deck mounted on a top of said frame,
• a cargo barrier extending around a periphery of said deck that includes a walk-off gate near the front end of said trailer to enable personnel to ingress/egress during a water-launching event of said trailer while attached to said towing vehicle and a ramp segment near the rear end of said trailer to enable said ATV to drive-on and drive-off said trailer while attached to said towing vehicle,
• an axel mounted on an underside of said frame for carrying a pair of wheels, each being positioned on a respective side of said frame,
• a floatation system to provide buoyancy in water, said floatation system including a series of individual buoyancy segments mounted on the underside of said frame,
• a propulsor to propel said trailer in water, and
• a wheel torque coupling disposed on a bed of the trailer to removably couple drive wheel torque of the ATV with the propulsor in order to propel the trailer through water.
