Abstract
A boat portage dolly for a boat that includes mounting gudgeons (30) on the transom (34), the dolly having a bifurcated carriage (20) with downwardly distending legs (22) attached to an upright frame member (24). The upright member also contains a pair of apertures (28) and an axle (36) is attached between the distal end of the legs. A wheel (40), preferably including a pneumatic tire, is rotatably mounted on the axle. The dolly is mated to the boat by placing the apertures over the gudgeons and penetrating holes in the gudgeons with a bent rod (44) that is contiguous with the inner surface of the carriage, holding the dolly in place tightly against the transom of the boat. The boat is portaged to water by lifting the bow by a single person and wheeling the vessel wheelbarrow fashion. Other embodiments change construction techniques of the carriage and retaining means.
