Abstract: The desirability of performing self-propelled model tests of icebreaking ships is outlined. Scaling relationships for modelling icebreaker performance are dis­cussed briefly. Model test techniques employed by the U. S. Coast Guard at the Naval Undersea Research and Development Center are reviewed. The results of the tests of models of the Wind class icebreaker and a new hull form are presented. Correlation between model and full-scale is demonstrated by comparing the results of full-scale and model trials of the Wind class icebreaker. The model test re­sults revealed-theoretically predicted differences in absolute icebreaking resistances and also showed effects of hull form variations.
