A series of experiments was initiated at IMD's model ice basin to determine the experimental error that may be expected in the results of ice resistance tests. A set of nine ice sheets was dedicated to the study, in which a 1 :20 scale model of the R-Class icebreaker was tested in EG/ AD/S model ice. The test length for each model resistance test varied from one and one-half model lengths to two and one half model lengths for the higher velocities, as well as several tests through the full length of the ice sheet ( approximately 70 m). The test results were corrected to nominal ice conditions according to standard IMD procedures, and these results were then compared to determine the resistance variation.
