boat trailer winch

Abstract
An improved boat trailer winch mechanism that involves an adjustable triangular assembly comprising a first and second vertical support means attached to each other at the apex and to the tongue of a boat trailer forming the base. Extending rearwardly from the adjustable triangular assembly is a novel bow engaging mechanism capable of pivoting and adjusting such as to make contact on both sides of a boat hull. Cantilevered upward and forward from the triangular assembly is a third support member and manual winch with strap and hook closure. Preferably, the strap is directed downward to the tongue and selectively to the proper height through the rear structural member to the triangular assembly such as to insure proper tension when loading or transporting a boat on the boat trailer. Such a boat trailer winch allows the loading of a small pleasure craft onto a boat trailer without leaving the boat and risking getting wet in less time than previously known boat winches.
