The angle of list is the degree to which a vessel heels (leans or tilts) to either port or starboard at equilibrium—with no external forces acting upon it.{{cite book|first=Peter|last=Kemp|title=The Oxford Companion to Ships and the Sea|isbn=0192115537|year=1976|page=[https://archive.org/details/oxfordcompaniont00kemp/page/488 488]|publisher=Oxford University Press |url-access=registration|url=https://archive.org/details/oxfordcompaniont00kemp/page/488}} If a listing ship goes beyond the point where a righting moment will keep it afloat, it will capsize and potentially sink.{{Cite book|last1=Barrass|first1=Bryan|url=https://books.google.com/books?id=4E4FZ988AtYC&dq=ship+roll+stability&pg=PA366|title=Ship Stability for Masters and Mates|last2=Derrett|first2=D.
