• b) two side steel plates comprising holes for mounting to a bow roller assembly of said trailer, an additional hole in each said side plate for receiving and mounting the "J" shaped rod, and a further hole in each said side plate for attaching a triggering device;
• c) a bent steel plate forming said triggering device, said bent plate defining two parallel flanges connected by an intermediate portion of the bent plate, each flange including a respective flange aperture connected with the further hopes of the side plates via intermediate fastening means;
• and
• d) a standard compression spring operatively connected to said roll pin and one of said side plates for biasing said "J" shaped rod to a boat engaged position,
• wherein said bent plate is movable from a position wherein said bent plate holds the "J" shaped rod in a cocked position disengaged from said boat to a position wherein said "J" shaped rod is free to respond to the bias of the compression spring and engage the boat eye bolt.
