Maneuvering motions of fishing vessels are important in the situation of fishing operation at slow ship speed. Especially the roll motion of the fishing vessel relates to the capsizing by steering motion in the situation of small metacenter height GM due to lifted net full of fishes on deck and the movable net lifted by winch ropes. This paper deals with the surge, sway, yaw and roll motions of two steered fishing vessels, which are simulated by the component-type mathematical model of ship hull hydrodynamic forces for the North European fishing vessel L/B=2.6 and the Japanese fishing vessel L/B =4.6. By comparing the results of free running measurements with the numerical simulations based on captive model tests for hydrodynamic forces acting on the hulls, it is found that the component-type mathematical model can estimate the maneuvering motion with roll and running trim precisely.
