A review of methods of calculation of added resistance for ships in a seaway

Wilson, P.A. (1985) A review of methods of calculation of added resistance for ships in a seaway Journal of Wind Engineering and Industrial Aerodynamics, 20, (1-3), pp. 187-199. (doi:10.1016/0167-6105(85)90018-2).

Most recent studies of performance and assessment of auxillary wind powered ships have been based primarily upon the calm water resistance of the ships 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 via 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 sets out to review the present day methods that are used to calculate ‘added resistance’ as it is often termed. This will allow, hopefully, designers and practitioners of wind powered vessels to discriminate between the different methods that are now available.
