ABSTRACT:
A latch assembly for securing a boat to a trailer for loading the boat onto the trailer although the boat may be floating at varying water levels relative to the trailer. The latch assembly includes a first latch, provided with a retentive framework and spring loaded door, mounted on the bow of a boat and a second or mating latch, having a framework provided with an elongated and vertically oriented latch pin. The framework of the mating latch is hingably mounted to a trailer post located adjacent the front of the trailer so as to incline in conformity with the bow of a boat. The spring loaded door of latch strikes the elongated latch pin at a vertical position dependent upon the water level, boat height, and trailer level and opens and then closes to captivate the latch pin. As the trailer is removed from the water, the latch slides down the latch pin until the boat rests upon the trailer bed.
