A 16 scale model of a mechanical cutting river icebreaker was designed, constructed, and test in Pennsylvania Lakes in four inches of ice. The vessel cut two cantilever beams, which were broken into regular pieces and displaced under the fixed ice at the sides of the cut channel thus producing a completely clear channel. Hull design, tool performance, and hull resistance data are presented and analyzed. Author
