In this paper the damping coefficient of roll for patrol boats engaged in Major Coasting Areas (generally, represented, in N) has been investigated, and a method to obtain the damping coefficient of ship for any condition was presented, analysing results of tank experiments of nine models.The mothod is ; first a standard N for standard conditions is obtained from a chart, (the N is fuction of bilge keel size and C_〓 while d/B, KG/d_0 and K/B constant), then corrections for d/B, KG/d_0,K/B are done by properly prepared charts.where C_〓=maximum sectional area coefficient of the ship d=draft of the ship B=beam of the ship KG=vertical position of center of gravity of the ship above base line d_0=standard draft K=radius of gyration of the ship
