Abstract
Abstract A portable boat dock consisting of a modified "H" shaped platform adapted to reside substantially underwater, the platform having attached to it two upwardly protruding arms with cradle members attached to engage opposite sides of a boat to be docked. The platform lower portion consists of a pair of spaced apart angled legs adapted to penetrate a distance into the lake bottom to secure the platform. Holding the platform upright is an attached elongated tongue, the tongue also operably attached to a front holding stake driven into the ground at the shoreline of the lake, the stake also containing a ring to receive a rope from the bow of the boat to secure the boat. The invention may be easily placed into the lake and removed by utilizing connecting pins which permit separation of the platform from the tongue and from the front stake. Various lake depths are accounted for by telescoping legs and various sized boats are accommodated by spreading or narrowing the angle between the upright cradle members.
