ABSTRACT:
A combined towing and docking hitch for watercraft. The hitch includes an elongated frame with a cable winch, a rearward yoke subframe, and a forward coupler. The coupler is adapted for mating with a complementary receptacle or receiver, mounted either on the stern of a towing boat or a boat dock. A cable or fiber web extending from the winch is attached to the bow eye of the towed or docked watercraft. The cable is advanced forwardly to draw the bow into nested engagement with the yoke. The yoke includes a pair of rearwardly diverging stabilizer arms having resilient bumpers on each end. A V-shaped roller is provided adjacent the converging region of the arms to accommodate the front bow stem of the towed watercraaft. The frame is pivotally attached to the coupler to accommodate wave-induced pitching movement, between the two vessels or between the moored watercraft and the dock.
