The angle of list is a term used to describe the degree to which a vessel

Watercraft

A watercraft is a vessel or craft designed to move across or through water. The name is derived from the term "craft" which was used to describe all types of water going vessels...

 heels (leans, or tilts) to either port or starboard.

A listing vessel is stable and at equilibrium, but the distribution of weight aboard causes it to heel to one side or the other.

List refers to a ship leaning to one side under stable conditions, often caused by uneven loading or flooding. By contrast "roll" refers to the dynamic movement from side to side caused by waves.

If a listing ship goes beyond the point where a righting moment will keep it afloat, it will capsize

Capsize

Capsizing is an act of tipping over a boat or ship to disable it. The act of reversing a capsized vessel is called righting.If a capsized vessel has sufficient flotation to prevent sinking, it may recover on its own if the stability is such that it is not stable inverted...

 and potentially sink.
