Abstract: A system and method using a self-activating stop device at the back of a boat trailer and providing an automatic unsecured status (US) indication to a boat driver as the boat is being driven out of the water and onto the trailer. The stop device includes a housing having a retractable stop element pivotably positioned therein and having a transmitter-detector assembly that communicates with a remotely-located receiver and indicator on the boat dashboard. As the boat is driven onto the trailer, the boat pivots the stop element down into the housing, activating the transmitter to send a signal to the receiver and illuminating the indicator while the stop element is depressed in the housing. Once the boat transom passes over the stop element, the element pivots upward acting as a stop against the transom, thereby preventing the boat from sliding back off of the trailer and shutting off the transmitter and the US indication.

Abstract: An apparatus and method for providing a self-activating stop device at the back of a hauling trailer for a boat. The apparatus is a compact, lightweight and durable U-shaped housing having a retractable stop element pivotably positioned therein. Through-holes in the housing permit the apparatus to be quickly and easily secured to bunkers or other framing at the trailer back end. The U-shaped housing's top surface can be easily aligned with the top surface of the bunk or framing while the stop element is biased in an upright position. When the boat is lifted out of the water and slid onto the bunker or framing, the boat's presence pivots the stop element down into the housing and once the transom of the boat passes over the stop element, the stop element self-activates, pivoting upward acting as a stop against the transom, thereby preventing the boat from sliding back off of the trailer.
