The marine steering system typically includes the following components: Steering wheel: The steering wheel is the primary control that the captain uses to steer the boat. It is connected to the helm, which is the mechanism that turns the boat's rudder. Helm: The helm is a mechanism that translates the turning of the steering wheel into movement of the boat's rudder. There are two types of helms: mechanical and hydraulic. Rudder: The rudder is the fin-like structure located at the stern of the boat that turns the boat when it is moved by the helm. The rudder is usually made of metal or fiberglass. Steering cables or hydraulic lines: These are the means by which the movement of the helm is transmitted to the rudder. Mechanical systems use cables, while hydraulic systems use fluid-filled lines. Autopilot: An autopilot is an optional component of the steering system that can be used to maintain a constant heading without requiring the captain to manually steer the boat. It is especially useful on long voyages. Compass: A compass is a navigational aid that can be used to determine the boat's heading. It is usually mounted on the helm or dashboard. Steering gear: The steering gear includes all the components that are involved in transmitting the movement of the helm to the rudder. This includes the helm, cables or hydraulic lines, and the rudder itself.
