An affix-type multipoint pressure sensor was developed by using the Fiber Bragg Grating (FBG) technology. In the 1st report, the measurement system of FBG pressure sensor was described and the performance was confirmed in a pressure measurement test on a circular cylinder in uniform flow. In the 2nd report, the FBG pressure sensors were stuck on the surface of the fore- and aft-body of a model ship and resistance tests were conducted. The FBG pressure sensor enables to measure the multi-point pressures on curved surfaces of a ship with the temperature compensation. The measured pressures were compared with the result of CFD calculations, and the effects on the ship's resistance were investigated. It was found from the experimental results that the FBG pressure sensor is effective to measure multipoint pressure on the surface of the model ship in resistance tests.
