ABSTRACT:
The personal motorcraft trailer has a lower shell which is capable of flotation and planing on a body of water. An upper shell has a lip which fits over the edge of the lower shell forming a sealed pod in which gear and supplies may be stored. At least a portion of the upper shell is openably attached by a hinge. The upper shell has two recessed areas in its upper surface, the rear recessed area being deep enough for holding fuel containers and the forward recessed area being relatively shallow and concave to accept gear such as surfboards or skis which are held in place by elastic cords stretched across the gear from hooks on the sides of the upper shell. The trailer is towed behind the motorcraft by a tongue the prongs of which attach at two clips, one on either side of the lower shell. Each prong of the tongue catches under the lip at the front of the trailer to prevent the trailer from digging into the water, causing it to flip. The shells of the trailer are molded of lightweight plastic or similar polymer to make the trailer easy to lift and transport. In an alternate embodiment for use with snowmobiles, the same structure as above is fitted with skis or rails on its bottom surface to permit the trailer to move smoothly through snow or on ice.
