Abstract Arctic ships move in broken ice most of the time. Therefore, forecasting the ice performance of ships when moving in a channel behind an icebreaker or in natural broken ice is relevant at the design stage. For this, theoretical and experimental studies of the movement of various models of ships in a small experimental basin were carried out. The process of modeling and testing of models of active ice navigation ships in a composite ice model is described. Test results and formulas for assessing ice resistance are given. They are derived from the analysis of model tests. Conclusions about the possibility of carrying out and obtaining reliable results of the experiment in small experimental pools are made. The resistance when moving ships in a wide ice channel does not differ from the resistance when moving ships in a field of broken ice. The jamming of ice floes between the edges of the channel and the side occurs when ships move in a narrow channel. Consequently, the “buffering effect” occurs and the resistance increases significantly.
