Abstract: An automatic boat to trailer latching device. The invention is designed primarily to facilitate one person boat to trailer recovery operations, particularly in less than ideal conditions, such as choppy water surface, cross winds, and after dark or predawn recoveries. The invention allows operation of the boat to trailer latching mechanism without requiring constant vertical alignment of the boat and trailer, without requiring longitudinal alignment of the boat and trailer during the approach and permits one person to complete the operation either in the boat, or behind the boat, in daylight, or darkness, in positions where the actual latch mechanism cannot be visually observed. The invention is a boat to host trailer latch assembly generally comprised of an elongated vertically extended latch bar adapted to be secured to the prow of a boat and a latch structure adapted to mounted on the forward end of a boat trailer.
