The purpose of this research is to compare and analyze the advanced speed of ships with different rudder controller in wavy condition by using a simulation. The commercial simulation tool named AQWA is used to develop the simulation of ship which has 3 degree of freedom. The nonlinear hydrodynamic force acting on hull. the propeller thrust and the rudder force are calculated by the ad... https://danddcollectiblers.shop/product-category/pitcher/
