Resistance and Motion Test for Catamaran Hull with Hydrofoil

This type of catamaran hull has a small resistance value but has a wider platform area for superstructure. However, the catamaran has a distance between the hulls that is passed by the flow of water. In this case, the distance between the hulls is used for the placement of the hydrofoil. The placement of the hydrofoil between the hulls does not interfere with the ship docking process. However, problems encountered with such laying force the spanwise size to be along the distance between the hulls. So that the value of the angle of attack and the placement of the airfoil are crucial because based on the simulations that have been carried out, especially for high speeds, the ship experienced an "accident" or experienced excessive trim. This is evidenced by the value of the pitching angle which goes up and down and is not stable.
