and:
Buoyancy per metre

By integration, the wave shearing force is:

Since Fis zero at x = 0, the constant is zero.
Integrating again the bending moment is:

Putting x = 70 the wave bending moment at amidships is found to
be 718MNm sagging. With the wave crest amidships the wave
moment would be of the same magnitude but hogging. The total
moments are obtained by adding the still water and wave
moments, giving:

Sagging = 797+ 718 = 1515MNm
Hogging = 797-718 = 79MNm

Had the mass of 5000 tonnes been distributed uniformly over the
whole ship length the still water bending moment would have
