A REVIEW OF THE METHODS OF CALCULATION OF ADDED RESISTANCE FOR SHIPS IN A SEAWAY

Most recent studies of performance and assessment of auxiliary wind powered ships have been based primarily upon the calm water resistance of ship's hull. This resistance is then used as a first estimate of the power required to drive the ship in a seaway. Some allowance has been made to this estimate for weather and seaway by means of a weather margin'. For many years theoreticians have produced methods for the calculation of this weather margin of a ship in a random seaway due to the induced rigid body motions. This paper reviews the present day methods that are used to calculate added resistance' as it is often termed. <CMO>.
