Abstract
This article uses the model test to investigate the effect of static trim angle on the hydrodynamic performance of a Semi-Planing Catamaran (SPC) named AUT-SEM00. First, the resistance test results in calm water at different speeds for static trim angles of 0.00 to 4.00 o are presented. The best static trim angle, hence the lowest resistance, is 2.0o at a speed of 3.78 m/s, which leads to the dynamic trim of 2.5o. Then, the model test in three regular waves in a range of static trim angles is conducted, and the results are analyzed. It has been seen that the best static trim angle, in comparison to the other trim angles, depicts up to 9% less resistance. Additionally, it is shown that the static trim angle does not significantly affect pitch motion and vertical accelerations. As far as the regular wavelength is concerned, the pitch and accelerations on the Center of Gravity (CG) and Fore Perpendicular (FP) rapidly increase as wavelength increases. There is a strong correlation between vertical acceleration and pitch motion, where both have the same tendency concerning the wavelength.
