Ship's Maneuverability in Strong Wind [PDF]
Journal of Navigation and Port Research, 2008 This paper deals with effect of wind forces and moment acting on the training ship SAE NURI. The results of drift angle and counter rudder angle due to wind effect are calculated by using the static equilibrium method especially with nonlinear mathematical expression, and then the critical wind velocity is found out.
