Abstract
Abstract A kayak or similar water craft includes a releasable deck that allows the operator to easily evacuate the craft during an emergency. A plurality of large headed pins are preferably employed to attach the releasable deck plate to the upper surface of the hull of the vessel. The head of the pin is received in the large opening of a key hole which includes a slotted groove portion. When the pin is received in the groove portion the deck plate is securely fastened to the kayak. Forward pressure exerted by the operator causes the pins to slide out of the key holes, thereby releasing the deck plate from the craft. The deck plate is held in place by a holding handle or a clip and detent arrangement until it is ready for release. The purpose of the invention is to make it safer for water craft operators to safely and effectively evacuate a vessel during an emergency.
