APPROXIMATE METHOD FOR STABILITY ARM EVALUATION AT INITIAL SHIP DESIGN STAGES

In this paper a simplified procedure for static and dynamic stability arms calculation at equivolume inclinations is presented, employing the three-parameter Lewis forms technique for reconstruction of the cross sections in a semi-fixed (rotational) coordinate system, the sectional data being obtained by preceding optimisation full form evaluations. The easiness of the procedure, unburdened by excessive inputs makes it applicable for the purpose of preliminary ship design.
