This report presents the results of resistance and propulsion tests in level ice of a roughened 1:20 scale model of the Canadian Coast Guard R-class icebreaker. The test conditions were the same as those previously reported for the smooth model. The present test results and those with the smooth model are compared, as are the results obtained at all facilities participating in the comparative study proposed by the Committee on Performance of Ships in Ice-Covered Waters of the International Towing Tank Conference. Keywords: Icebreaker; Ice resistance; Model tests; Propulsions.
