The helm on a sailboat is the command center and mechanism used to steer, typically comprising a tiller or wheel connected to the rudder. Located in the stern (rear) of the boat, it allows the helmsman to control direction, with wheels common on larger boats and tillers on smaller ones. The helm often includes navigation instruments and throttles.

Key Components of a Sailboat Helm System
Wheel: A circular device used to steer, common on larger boats, often connected to the rudder via cables, chains, or hydraulic systems.

Tiller: A lever or arm connected directly to the top of the rudder stock, used for steering, typically found on smaller sailboats.

Rudder: The underwater blade connected to the helm that turns to redirect water flow and steer the vessel.

Pedestal: On wheel-steered boats, the structure that holds the steering wheel and usually houses instruments and the compass.

Steering Linkage: The mechanism (cables, rods, or hydraulics) that connects the wheel or tiller to the rudder, transmitting motion.

The helm is essentially the "command center" of the vessel, crucial for safe navigation.
