“Breadth of the ship” means the extreme width from outside of frame to outside of frame at or below the deepest subdivision load line.

“Bulkhead deck” means the uppermost deck up to which the transverse watertight bulkheads are carried.

“Cargo area” means that part of the ship that contains cargo tanks, slop tanks and cargo pump-rooms including cofferdams, ballast and void spaces adjacent to cargo tanks and also deck areas throughout the entire length and breadth of the part of the ship over the above-mentioned spaces.
