Correlations between hull form factors and behaviors of hydrodynamic force acting on lateral motion ships were investigated, and response to water depth change at shallow water area was clarified. The shallow water effects to maneuverability were well known by the ship operators, however, the accidents caused by that factor will not disappear. Recent increase of ship size is significant, and the needs for attention on shallow water effects has been serious.
NISHIO et al. (2025) studied this question.
