A boat's steering wheel connects to the rudder, allowing the captain or helmsman to change the vessel's direction. Some modern ships don't have a wheel, instead opting for a toggle that changes the rudder direction through remote control. The steering wheel on a boat is the ship's wheel or the boat's wheel. It is a part of the helm's steering mechanics, that changes the rudder's direction to vary the vessel's course. In recent times, it is well-known as the helm rather than the steering wheel. The steering wheel or helm will be much smaller than you might think, with some modern boats having simple toggle switches. Key Features: The grip is dense PVC.
