A review is made of the development of damage stability criteria over the last 25 years. In 1952 there were only two standards for intact stability: the wind-heel and passenger-heel criteria of the U.S. Coast Guard. The former established unit wind pressure for various locations and the latter called for all passengers to be placed so that their weight centre was 1/6 of the beam from the ship centreline. After World War I the prime emphasis of the (U.S.) Navy in assessing the stability of ships was on their ability to resist flooding in case of damage. It was not until 1975 that the criteria were formalised in Navy Design Data Sheet, DSS 079-1, which embraced the investigation of heel in high-speed turns, heel caused by lifting weights on and off, and heel due to passengers and crew shifting to one side of the vessel; this work was based on work done by a Frenchman at the turn of the century. Experience and casualty records seem to indicate that the U.S. Coast Guard windheel and passenger-heel criteria are now adequate to ensure stability in large vessels that comply with them.
