In canal and seaway the ship speed must be reduced and it has been a subject for many research studies. One of the most important phenomena connected to this issue is the increasing of ship draught when passing in the restricted water which is called squat. This study deals with the squat thorough systematic model testing. Two models from Series60 body form have been tested in a set of canal depth, width as well as different model speed. The change on their draught has been recorded at fore and aft of the model. The test results have been manipulated, validated and regression formula has been developed for prediction of squat at ship fore perpendicular. The formula has been compared with the other existing formula where a good agreement achieved. The advantage of the new formula is the coverage on wider range of parameters affecting the ship squat.
