ABSTRACT:
A trailer adapted to carry in piggy-back fashion, a removable, replaceable dolly onto which small or personal watercraft is to be loaded or off-loaded. The trailer is provided with higher pressure tires capable of withstanding such impacts and jarring as are associated with highway usage, while the dolly is provided with lower pressure tires for travel over sand, dirt, gravel, or other off-the road use. A first stop, on the trailer, limits movement of the dolly once secured; and a second stop, on the dolly, limits the movement of the watercraft. A plurality of rollers are employed to ease the dolly loading with the trailer, and the watercraft loading with the dolly.
