Abstract
This paper follows the previous one published at PACON 90. Analyzing 78 towing test data in still water of high speed craft 2.5 m length models by so-called principal component analyses, a presumption of resistance performance including total resistance coefficient, change of trim and of draft is proposed by using eleven non-dimensional hull form parameters including length, width, height of chine at midship, initial trim and so on. Results by two kinds of empirical formulae are favorably compared with the test data. Five more new models were tested to reconfirm those formulae, and we obtained reasonable correspondencies. Both formulae, therefore, are adequately clarified as applicable, defining two kinds of applicable ranges inside such as either the tolerance ellipse containing 95% data or the Cramér’s concentrated ellipse containing 75 % data.
