A ship 's wheel or boat 's wheel is a device used aboard a water vessel to change that vessel 's course. Together with the rest of the steering mechanism, it forms part of the helm. It is connected to a mechanical, electric servo, or hydraulic system which alters the vertical angle of the vessel 's rudder relative to its hull. In some modern ships the wheel is replaced with a simple toggle that remotely controls an electro - mechanical or electro - hydraulic drive for the rudder, with a rudder position indicator presenting feedback to the helmsman.
