Abstract:
Ship Movement is an important factor in shipbuilding. In determining the  ship's  maneuverability,  there  are  many  aspects  that  must  be considered in the design, namely resistance and angle of attack of the waves. In determining the angle of attack of the waves, the test uses the  trigonometry  principle  to  determine  the  angle  of  attack  of  the waves. Where the results of the 3 maneuvers of the Heave, Roll and Pitch ships at speeds of 0 knots, 0.389 knots, 0.778 knots, 1.166 knots, 1943 knots, it is known that the displacement model ship can be used in an open area with a set scale
