In this paper, large bow and stern bulbs installed on the center plane of a catamaran are suggested, and their wave making characteristics to reduce the wave making resistance acting on the catamaran in high speed range are discussed by means of model experiments and numerical analyses based on the panel method. Wave making characteristics of bulbs are investigated by using the panel method PAFS (Panel method Applied to Free Surface flow), in which Morino's panel method for lifting bodies is extended to the problem of free surface flow. According to the simulation results based on PAFS, at Froude number 0.5 which is around the last hump of wave making resistance coefficient curve, about 40 to 45% reduction of wave making resistance can be expected for the present catamaran model.
