Model tests of propeller performance in bollard conditions, in deep and shallow water, were carried out atShip Design and Research Centre in Gdańsk. Corresponding calculations of propeller performance with ac-count for finite dimensions of canal cross-section were carried out at Wrocław University of Technology byusing their own theoretical model of propeller – hull interaction. The calculations were carried out in modelscale, at the same water depth as in model tests. For given hull form, propeller geometry and canal cross--section the HPSDK computer code was used to calculate wake fraction, as well as propeller thrust, torqueand efficiency. The distribution of pressure on waterway bottom and ship sinkage were also determined
