Resistance of Transom-Stern Craft in the Pre-Planing Regime

Abstract

An analytical procedure is presented for predicting the resistance of transomstern hulls in the non-planing range -- specifically for volume Froude numbers less than 2.0. The predictive technique is established by a regression analysis of the smooth-water resistance data of seven transom-stern hull series which included 118 separate hull forms. The statistically-based correlation equation is a function of slenderness ratio, beam loading, entrance angle, ratio of transom area to maximum section area and volume Froude number. This equation can be used to estimate the low Froude number resistance of planing hull forms in the early stages of design.
