Nowadays, naval architects have been facing a great challenge to obtain an optimum<br />

resistance prediction related to inherent geometrical configuration of the catamaran.<br />

This project presents an optimization numerical analysis using Design of Experiment<br />

(DOE) approach incorporated with ANSYS Fluent to obtain optimum resistance<br />

prediction with respect to a several geometrical configuration of the rounded<br />

catamaran hull form. In this computational simulation, Froude number, various lateral<br />

separation ratios (S/L) and longitudinal stagger ratios (R/L) have been taken into<br />

account. The results revealed that the optimum resistance for various S/L ratios were<br />

in the range of Froude number from 0.47 to 0.66. In addition, the optimum resistance<br />

falls within the range of 0.47 < Fr ≤ 0.66 with various R/L ratios.<br />
