In this study, a roll motion estimation of fishing vessel with water on deck is investigated. Firstly, the characteristics of roll damping of a fishing vessel are investigated through the experiment. The Ikeda's method is modified for the improvement of accuracy of roll damping of a fishing vessel. Secondly, the effects of water on deck are investigated through the experiment. A database of hydrodynamic forces caused by water on deck is developed. In addition to the nonlinear calculation program of it based on shallow water theory is developed. Finally, roll motion of a fishing vessel with water on deck in beam sea is calculated. The results are compared with the measured results, and its validity is confirmed.
