The paper surveys the situation with regard to the three-dimensional extrapolation of ship form frictional resistance from model to ship. It is suggested that current three-dimensional extrapolation methods be adapted to the two-dimensional method recently adopted by the International Towing Tank Conference at Madrid (I.T.T.C.-1957 method). The consequences of the application of three-dimensional extrapolation are reviewed, particularly as regards the effect of roughness on skin friction resistance, the resistance of shaft appendages and the effect of restricted water on the magnitude of the frictional resistance. Diagrams and tables are given to facilitate the application of three-dimensional extrapolation.
