BREADTH MOLDED - is the breadth of the hull at the widest part, measured between the outer surfaces of the frames.
BREADTH REGISTERED - or extreme breadth is the breadth of the hull at the widest part measured between the outer surfaces of the shell plating.
DEPTH MOLDED - is the depth measured between the top of the keel, or lower surface of the frame at the center line, and top of the upper deck beam at the gunwale, or to the top of the second deck beam in a shelter or awning deck vessel.
