ON THE PRACTICAL EVALUATION OF SHALLOW WATER EFFECT IN LARGE INCLINATIONS FOR SMALL FISHING BOATS

This paper describes the classification of characteristic behaviour of shallow water on a ship's deck, based on model tests using an oscillatory rectangular tank physically simulated with sinusoidal motion. From the viewpoint of transverse stability in small fishing boats, the author paid attention to two types of complicated behaviour, which appeared near the first and second resonant periods between the shallow water and the ship. These phenomena in large inclinations were simulated using the Marker-and-Cell method and solution algorithm for transient fluid flow in order to obtain an equation for the motion of shallow water. Tank tests using a general model of small fishing boats were carried out with shallow water on the deck in beam waves. From the results of rolling motion and transverse force of shallow water, shallow water effect on transverse stability was practically evaluated.
