ABSTRACT:
A device for temporary application to the hull of small craft to close accidental breaches in the hull which includes a mat having a raised annular wall to surround and close off a breach from the water surrounding the hull. Suction cups are arranged on the mat around the wall to hold the mat against the hull. Reinforcing ribs can prevent pressure collapse of the mat within the wall and internal mechanical fastenings may supplement the action of the suction cups.
