The seakeeping performance of trimaran is crucial to its design and development. A series of trimaran model tests for seakeeping performance are conducted in towing tank. Directional spectrum theory and long-crested wave theory are introduced to the spectrum analysis method so as to analyze the motion response of trimaran. The comparison of the results gaining from two theories and those achieving from the long-crested irregular wave tests is carried out. By statistical analysis, there is a big difference between the motion responses of trimaran according to different wave theories in several operating conditions. The characteristics of trimaran motion responses under different course angles are studied. Compared with long-crested wave theory, directional spectrum theory is introduced as a more accurate approach to research the seakeeping performance of trimaran.
