THE RESPONSE OF SMALL CRAFT TO WAVE ACTION

M. Isaacson, A.G. Merger

Abstract


A comprehensive study has been conducted for the Small Craft Harbours Branch, Department of Fisheries and Oceans Canada, to provide improved criteria for acceptable wave climate in small craft harbours (Ref. 3). An important part of the study was directed to model tests of vessel response to waves, and comparisons of these to field measurements and to simplified analytical predictions. The objective of the present paper is to describe these specific comparisons and present the corresponding results in the context of improving harbour entrance designs. The model tests results and theoretical predictions are adequate to show quantitatively the dependence of a sailboat's response to different wave lengths with sufficient accuracy for wave periods, heights and directions to be selected as variables in formulating the required wave criteria.
