Influence of outrigger position of a high speed trimaran on the maneuverability was investigated. 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 ι/L=0.375 where ι denotes the outrigger length. The captive model tests were conducted at F_n=0.35 in towing tank of Hiroshima University to capture the hydrodynamic force characteristics of the trimaran with 3 different outrigger positions. Baesd on the force characteristics, maneuvering simulations were carried out. We found that with shifting the outrigger position rearward, the turning circle becomes large and the course-keeping ability is improved. The change comes from increase of lateral resistance at the stern part.
