Several important factors such as the metacenter point, the center of gravity and the center of buoyancy that is prevented from rolling unexpectedly need to be considered to create stability in the ship. In this paper, a fast single craft that can move at the maximum speed of 120 kilometers per hour is investigated and analyzed in terms of design and dynamics stability. According to the results of simulation, the drag and lift coefficients are 8.96×105 and 1.46×106 in the motion of single craft respectively. Also the results are desirable if the lift to drag ratio be more than one (Accordingly this ratio is calculated 1.62 in this paper). In the analysis of the movement of the vessels based on the drag and lift coefficients as 2.48×105 and 8.39×105 respectively, the ratio of the two coefficients is 3.38 which indicates the accuracy of the results.
