A ship wheel, also known as a helm or steering wheel, is a device used to steer a ship or boat. It is typically mounted on the bridge and connected to the rudder, which directs the vessel's movement through water. Ship wheels can vary in size and design, but they usually have spokes radiating from a central hub, allowing the helmsman to easily control the direction of the ship. The operation of a ship wheel involves turning it left or right to change the ship's course. Modern ships may use electronic systems for steering, but traditional wooden or metal wheels are still common on many vessels. The ship wheel is an essential tool for navigation and safety at sea.
