In recent Japan the structural design of high speed craft is based on "Keikozosen Zantei Kijun" (provisional standard of lighter hull structure) set forth by the Japanese Government (J.G.) and this standard is applicable only for the craft of its registered length less than 24 meters. A 45 meters long aluminum alloy passenger liner named "SEA HAWK" was constructed with the special approval of J.G. at the Shimonoseki Shipyard & Engine Works of Mitsubishi Heavy Industries, Ltd., and delivered to the joint ownership of Senpaku Seibi Kodan (Maritime Credit Corporation) and Tokai Kisen Co., Ltd. on April 18, 1977. A full scale measurement in short term was carried out on board "SEA HAWK" running at the service area near Izu Ohshima and the test data were obtained on the hull stresses due to the wave loads as well as the vertical accelerations and the motions of the craft. In succession to the short term measurement, long term measurement was carried out during one and half months in winter season at the same area. This paper gives the outline of the measurement and the comparison about the wave loads between the standard of J.G. and processed test data.
