In recently years, large high speed craft have been planned and constructed with hull of aluminium alloy for overall economical advantage. Increase in craft length causes relative decrease in rigidity of the hull girder. Therefore, the longitudinal strength of the hull becomes an important factor to be considered for designing large size high speed craft. In this paper, a new guide line of longitudinal bending moment of large high speed craft caused by high speed running in waves is presented. The amounts of beniding moment are explained by numerical calculations, segmented-hull model experiment and measurement on actual ships. The authers point out that special consideration should be paid on low speed, at the neighbourfood of sincronized condition of ship's motion in addition to high speed conditions apart from in case of small high speed craft.
