Recently, the expansion of the travel market and the increase in demand for leisure sports because of the weekend travel culture following the implementation of the five-day week system, leisure activities such as fields related to hobbies are becoming a major part. In this study, floating body analysis was performed according to the wave direction of the hull to analyze the effect of the wave cycle of the leisure boat. The research target boat is a 24ft-class leisure boat with a capacity of up to 6 passengers and operating at a maximum of 25 knots. Existing boats reduce the stern trim by installing interceptors, but in this study, they were not installed in order to evaluate the effect of waves. Floating body analysis was performed to evaluate the effect of waves, and the conditions necessary for the analysis were set based on the shipping environment, and the effect of the wave cycle was analyzed. this study verified the stability and stability of the leisure boat about waves, and Based on the result data, propose a management measure to efficiently reorganize the internal structural reinforcement.
