Full-scale testing was performed during this past winter on the air coating system, which was conceived to improve the performance of ships operating in broken ice and mush ice. The Great Lakes ore carrier Leon Fraser was modified to accept this system after model tests had been used to optimize the design. A relatively mild winter resulted in insufficient build-up of broken ice in the channels to effectively test the system. The data which was obtained indicated that a potential exists for the air coating system to reduce resistance in broken ice and mush ice. Measurements were also made of ice forces on the hull structure caused by impacting sheet ice and by hitting ice floes. Results of these mesurements have lead to the development of predictor equations for calculating ice forces.
