Model Tests on Two Models of WTGB 140-Foot Icebreaker

The results of resistance tests in level ice and broken ice channels are presented for two models of the WTGB 140-ft icebreaker at scales of 1:10 and 1:24, respectively. No scale effect on the resistance in level ice could be detected between the two models. From the test results an empirical predictor equation for the full scale ice resistance is derived. Predicted resistance is compared against, and found to be 25 to 40% larger than, available full-scale values estimated from thrust measurements during full-scale trials of the Great Lakes icebreaker Katmai Bay.
