Abstract
The paper studies parametric wave estimation based on the 'wave buoy analogy'. The ship motion data obtained from the training ship Shioji-maru are used for the estimation and the results are compared with estimates of the sea states obtained from other measurements and observations. Furthermore, the estimating characteristics of the parametric model are discussed by considering the results of a similar estimation concept based on Bayesian modelling. As a result, it is revealed that there is a distinct difference in the estimation of wave heights and wave periods. This is explained by referencing the concrete modelling procedure of the two approaches.
