Introduction
The steering wheel of a boat is an essential component that allows the operator to control the direction of the vessel. It is the equivalent of a steering wheel in a car or a handlebar in a bicycle. While the term “steering wheel” is commonly used to refer to this component, there is a specific nautical term that describes it.
The Helm
In the boating world, the steering wheel is known as the helm. The term “helm” originates from Old English and refers to the steering apparatus of a ship. It encompasses not only the wheel itself but also the entire system that enables the operator to steer the boat.
The helm consists of various components, including the steering wheel, cables or hydraulic systems, and the rudder or outboard motor. These elements work together to translate the operator’s input into a change in direction for the boat.
Types of Boat Helms
There are different types of helms used in boats, depending on the size, type, and purpose of the vessel. Here are a few common types:
1. Mechanical Helms: Mechanical helms use cables to transmit the steering input from the wheel to the rudder or outboard motor. These cables are connected to a rotary mechanism that converts the wheel’s rotation into a linear motion, which then moves the rudder or adjusts the outboard motor’s direction.
2. Hydraulic Helms: Hydraulic helms use fluid pressure to transmit steering input. They consist of a hydraulic pump, hydraulic lines, and a hydraulic cylinder. When the operator turns the wheel, the pump pressurizes the hydraulic fluid, which then moves the cylinder, causing the rudder or outboard motor to change direction.
3. Fly-by-Wire Helms: Fly-by-wire helms, also known as electronic helms, use electronic sensors and actuators to transmit steering input. Instead of mechanical or hydraulic connections, these systems rely on electronic signals to control the boat’s steering. The operator’s input is detected by sensors and sent to an electronic control unit, which then activates the appropriate actuators to move the rudder or adjust the outboard motor.
Steering Wheel Design
The design of boat steering wheels can vary, but they generally have a similar structure. Most boat steering wheels consist of a circular rim with spokes radiating from the center. The rim is typically made of a durable material, such as stainless steel or plastic, to withstand the harsh marine environment.
The size of the steering wheel can vary depending on the boat’s size and the operator’s preference. Larger boats often have larger steering wheels to provide better leverage, while smaller boats may have smaller wheels for easier maneuverability.
Some steering wheels also feature additional controls integrated into the rim or spokes. These controls can include buttons or switches for functions like horn activation, throttle control, or autopilot engagement. Having these controls within easy reach of the operator enhances convenience and safety while operating the boat.
Conclusion
The steering wheel of a boat is known as the helm. It is a crucial component that allows the operator to control the direction of the vessel. The helm encompasses not only the steering wheel but also the entire system that enables steering, including cables or hydraulic systems and the rudder or outboard motor. Different types of helms, such as mechanical, hydraulic, and fly-by-wire, are used in boats depending on their size and purpose. The design of boat steering wheels varies but generally consists of a circular rim with spokes and may include additional controls for convenience.
