We present a method for the estimation of the distribution of the quasi-static hogging-bending moment for a floating body. Starting points of this study are temporal characteristics of the sea state. The approximation is deduced from the estimation of the joint distribution of crest amplitude and crest length. The quality of the model is investigated by comparing computed distributions with empirical ones, originating from real measurements on which a Fourier snapshot-method has been applied. The question on how precise the representation of the sea state (the entire wave spectrum or only reduced parameters) needs to be in order to obtain proper densities for crest amplitude and crest length is also addressed.
