The damping effects of bilge keels, bilge fins and paravanes on the roll motions of a fishing vessel are studied experimentally using model tests in a towing tank. A 1:26.53 scale model of a 119 ft. long New England trawler was fitted with the different devices and excited in roll by a moment generator. The roll amplitudes and resistance at steaming and trawling speeds were measured and roll damping ratios calculated. Comparisons of the effects of the different damping devices are made.
