Abstract
The type of hull in the catamaran is developed by following the design criteria. A catamaran has advantages over a monohull in terms of broad layout, excellent stability, and obstacles on small vessels. The catamaran design follows the semi SWATH type design by having two hulls with a small hull front corner and modeling on INCAT wave-piercing catamaran to determine the structural response to the ship, and the wave slamming process. In the simulation analysis using fluid-structure interaction with RANS and also the strength of the catamaran structure using the FE method and large base scale. In modeling also to show the hydroelastic response to the ship structure that makes the dynamic interaction between waves and ship structure more practical. Then, the design optimization of the catamaran is directed to the addition of keel fins and the application of titanium materials.
