A study on hull design to improve resistance performance of small pleasure boats

This study was designed to propose a non-commercial “small pleasure boat” design of a catamaran with a vessel length of less than 12 meters, with relatively simplified construction procedures and safety inspection standards compared to general ships, in order to strengthen the design and design capabilities of small and medium-sized ships. Using the programs Rhino 4.0 & Maxsurf, stability and effective horsepower were calculated for the 1st, 2nd, and 3rd stages. A small pleasure boat design was proposed by applying a line with improved resistance. In order to propose a design to improve resistance performance, the resistance performance of symmetrical catamaran type A and asymmetric catamaran type B was calculated to calculate the required horsepower (EHP) for each ship speed and compare the resistance performance.
