The paper presents a study of hydrodynamic parameters related to ship squat acting on sailing ship MIRCEA hull in shallow waters, using CFD methods. The vertical hydrodynamic forces obtained in ANSYS CFX were analysed in respect with various domain depths and ship’s speeds, but also used for squat calculations. In order to evaluate the reliability of previously determined squat, a comparison study was made with nine of the most common empirical formulae for calculating squat in open shallow waters, ranging from Barrass to Huuska or Eryuzlu and Hausser. Some of these methods offer good results and were often experimentally validated with scale models.
