Abstract
Abstract My structure permits inverting a boat by one person for loading onto or unloading from the top of an automobile. In my structure a bow pin is attached to the bow of the boat and rotates in the yoke of a bipod supported on the ground. The transom or other end of my boat has a removably attached unit with dolly struts and wheels and a rotatable clevis. A trailer hitch attached to the rear of the automobile supports a vertical mast on which is rotatably and slidably mounted a guide having an integral tang. The tang is inserted into the clevis. The boat is cradled and adapted to be inverted between the bow pin and yoke on one end and the clevis and tang on the other end. The boat is adapted to be pivoted and raised or lowered on the mast for loading and unloading on top of the automobile.

Claim 1
Independent Claim
182 words
A structure for inverting a boat for loading on an automobile comprising a bow pin attached to the bow of a boat, a bipod having legs for positioning the bipod on the ground and having at its upper portion a yoke, said yoke adapted to receive and rotatably hold said bow pin of the boat, a clamping unit removably attached to the transom of the boat, a clevis rotatably mounted on said unit, a trailer hitch attached to the rear portion of an automobile, a vertical mast attached at its lower end to said trailer hitch, a guide means slidably and rotatably mounted on said mast, and having aN integral tang, said tang positioned within said clevis, and means for holding said tang within said clevis, means for raising the rear of the boat to half beam position so that the boat being cradled by said bow pin and said yoke on one end, and said tang and said clevis on the other end may be inverted 180* to bottoms-up position, said unit having means for holding the boat against further rotation.
