This report describes the full-scale testing of an auxiliary system for improving the icebreaking performance of ships. The system consisted of a set of blowers and piping installed within and on the hull in such a way that the exterior of the ships hull was covered from bow to stern and keel to waterline, with a layer of air bubbles. The purpose of the air flow was to entrain a flow of water which, in turn, would continuously wet the area of contact between the hull and the ice during icebreaking operations. It was anticipated that this would reduce the friction between the ice and the hull, and thus increase the speed of advance of the ship.
