Abstract: This report presents data on the full-scale rials of the U.S. Coast Guard Icebreaker Katmai Bay, which was tested in plate ice that varied in thickness from 10 to 33 in. (25.4 to 83.82 cm) and had a snow cover of 1 to 6 in. (2.54 to 15.24 cm). In January the average temperature was -5°C, and the ice flexural strength was 13,363 lb/ft^2 (640 kPa). In March the average temperature was -2°C and the ice flexural strength was 11,643 lb/ft^2 (560 kPa). The specific weight (density) of the ice was 0.894 g/cm^3. The specific weight of the snow was in the area of 0.32 g/cm^3. The coefficient of friction between the ice/snow and steel plate (coatea and uncoated) varied from a low of 0.02 in the dynamic case of ice on the Inerta 160 coating to 0.47 for the static case of snow on a rusty steel plate.
