We can consider the wave forces on a ship to be quasi-static. This means that they can be treated as a succession of equilibrium states.
When a wave passes by a vessel the worst hogging moment occurs when the midbody is on the crest of a wave, and the bow and stern are in the troughs
The design wave for a vessel will therefore have a wavelength equal to the vessel length.
The wave height (peak to trough) is generally assumed to be 1/20th of the wave length (any larger and the wave will break)
