WebDynamical stability. The dynamical stability of a ship at a given angle of heel is defined as the work done in heeling the ship to that angle very slowly and at constant displacement, i.e., ignoring any work done against air or water resistance.

"WebThe two types of curves may be compared as follows: 1. On cross-curves : Vertical values are righting arms. Horizontal values are displacements. Successive curves are for different angles of heel. 2. On stability curves : Vertical values are righting arms. Horizontal values are angles of heel. Successive curves are for different displacements. 4-7. " - Inclining a ship
