Heel in a high-speed turn is a governing factor in required stability on highly maneuverable ships. The heel towards the outside of the turn is affected by the velocity of the turn which is also associated with the turning radius.

High-speed turning is an application to estimate and display the potential conditions of intact stability on ships during high-speed turning operations. Only the ship's speed and turning radius input from the user on the vessel are needed to provide the qualitative results in a way to identify potential problems and tendencies to derive countermeasures.
