When a boat is loaded onto a boat trailer, it is locked on by the automatic latching device and is held in the full forward position by the winch strap. The boat keel is now on top of the automatic latching device which compresses the spring on a T-shaped member and increases the contact surface pressure between the automatic latching device and the boat keel. Any vertical movement or bounce by the boat keel during transport compresses the spring and adds additional pressure between the two surfaces. The automatic latching device and the boat keel are now joined together in effect as a unitary unit and moves in that fashion one relative to the other wherein movement is essentially transferred to the elongated holes in the winch stand uprights. By eliminating any movement between the automatic latching device and the boat keel, surface marking of the keel has been eliminated. Further, any likely wear of the contacted portion of the automatic latching device will be less.
