Influence of outrigger position of a high speed trimaran on the resistance and wave wash was investigated by the tank tests changing 9 outrigger positions of the trimaran model. The trimaran is composed of the center hull with L/B = 8.0 and B/T = 3.57 where L, B and T denote the length, breadth and draft respectively, and the outriggers with l/L = 0.375 where l denotes the outrigger length. The objective of this research is to provide a useful design data to quantify the resistance and the wave wash characteristics of the trimaran. The optimum location of the outrigger to minimize the resistance depends on ship speeds. The measured data will allow naval architects to balance hydrodynamic performance with other design considerations in the conceptual designs of high speed trimarans.
