In ship: Static stability
…float at unwanted angles of heel (sideways inclination) and trim (endwise inclination). Nonzero trim angles may lift the tips of propeller blades above the surface, or they may increase the possibility that the bow will slam into waves during heavy weather. Nonzero heel angles (which tend to be much greater…

In naval architecture: Heel when turning
…to reduce the angle of heel. Thus, in a steady turn, if the rudder angle is suddenly removed, the outboard heel is momentarily increased. Ships with small metacentric stability and comparatively large rudders have capsized through this cause.

In naval architecture: Situation after damage
Any heel after damage makes a ship vulnerable. Excessive heel may be disastrous, as it was for the Andrea Doria in 1956 and the Costa Concordia in 2012. In a well-designed ship, subdivision is planned to ensure that the ship remains upright, or nearly so, no…
