N2 - Numerical investigation of pressure distribution between two catamaran demihull was carried out: inside and outside of the configuration. The investigation was conducted using a commercial CFD code (CFX) on the slender model with the ratio of length to width (L/B) is 11.16 and the configuration was made based on different space to length ratio (S/L): 0.2, 0.3, and 0.4 together with different speed of ship. It is apparent that the inside pressure distribution is different from that of outside one, indicating that there is flow interaction between the demihulls. The interaction, which is later expressed as form factor (1+k) values showing that the catamaran form factor is higher than that of the demihull, i.e., 1.42 c.f. 1.26, which demonstrates an increase of approximately 13.6%.
