Object and purpose of research. This paper studies towing resistance assessment method in deep open water for icebreakers, supply vessels, and cargo vessels with high ice class. Materials and methods. The method suggested in this paper is based on the regression analysis of model test data obtained as per the form-factor scheme. The paper also suggests full-scale extrapolation formulae for wave resistance coefficient
