In preliminary ship design studies it is frequently necessary to estimate the calm water resistance characteristics of various hull forms prior to carrying out model tests. For such estimations, use is generally made of results of well-known methodical model experiments such as Taylor’s Standard Series, Series 60, and others to determine the effect of specific hull form parameters on resistance. For small, high-speed displacement vessels designed to operate in the speed range corresponding to Froude number values of 0.4 to 1.1 (equivalent to a range in V / L of 1.34 to 3.70), these well-known methodical series results are inadequate due to the limited speed range covered. Alternative methods must then be used. In this paper, all available and reliable data for the prediction of the resistance of small, high-speed vessels, designed to operate in the displacement mode, are presented. Included are the results of restricted and less well-known methodical series and averaged results of tests with a large number of non-systematic models, in both graphical and numerical form. Some basic considerations on how and when each of the presented methods can be applied are also presented.
