ABSTRACT:
A self-leveling boat trailer adapted to be towed behind a vehicle. In one embodiment, the trailer includes a pivotally mounted tongue assembly and a wheeled undercarriage. A flotation system at the stern end of the trailer causes the stern of the trailer to float upon entry into the water. A control linkage is utilized to pivot the tongue assembly in response to the flotation of the trailer stern, lowering the bow end of the trailer, thereby maintaining the trailer in a level position. In a second embodiment, the entire support platform pivots while the tongue assembly and wheeled undercarriage are coupled to a single rigid member. In either embodiment, boat launch and recovery are improved by maintaining the trailer in a level position despite the incline of a typical launching ramp.
