Navigating a ship is the act of controlling and directing its course. Steer a ship is a specific type of navigation that involves using a wheel or tiller to control the direction of the vessel. This is done by adjusting the rudder, which is a flat piece of metal attached to the stern of the ship that is used to change the direction of the vessel. Steering a ship requires skill and knowledge of the sea, as well as an understanding of the wind and current conditions.
