A Study on the Bilge Keels

Part 2. Full Sized Model Experiment

Abstract

In the present paper an empirical formula (1) for the fin resistance is obtained after analysing the results of the rolling experiments on the action of a full-sized bilge plate. And a method of approximate calculation of the rolling resistance to actual ships by the bilge keels is found by adding the above-mentioned fin resistance to the surface resistance calculated by the method given in the first report.
