Abstract
A portable watercraft lift including a pair of transverse, laterally spaced apart, arch shaped support members which are each detachably connected at the top thereof to one end of an elongated connector beam member. An electrically powered winch, having a winch drum, is detachably mounted on the elongated connector beam member at a point equidistant between the arch shaped support members. Each of the transverse arch shaped support members is provided with lifting cord means and associated pulley means, and one end of each of said cord means is operatively attached to the winch drum. Each of the lifting cord means and associated pulley means are connectable as a combination to a watercraft support member for supporting a watercraft by either a lifting ring, a cradle or lifting straps. When the power winch is operated the cords attached to the drum of the power winches are pulled in from both directions simultaneously creating a lift on a watercraft. The watercraft is lowered by reversing the operation of the power winch.
