The International Load Line Convention mandates that hatch covers must be weathertight. Rubber gaskets, compressed by steel bars and secured with cleats, create a seal that prevents water ingress. This mechanical arrangement is vital for maintaining the vessel's reserve buoyancy and protecting cargo integrity during heavy weather.
