Description

This application provides calculations for the resistance of a planing craft based on friction coefficient according to the ITTC 1957 lines, mean wetted length ratio and trim.

Mean wetted length ratio, trim, correction terms etc. are calculated from curves based on large number of model tests conducted by Savitsky (1964)

The formulae are from Principles of Naval Architecture(PNA) Vol II, section 9.2[c]
