What is the wheel of a ship called?

The wheel of a ship, also known as the ship's steering wheel or helm, is a device used to control the direction of the vessel. It is typically located on the bridge or the wheelhouse of the ship, where the steering is carried out.

Here are some key points about the ship's wheel:

1. Purpose: The primary purpose of the ship's wheel is to steer the ship, allowing the helmsman to change the course of the vessel as required.

2. Design: Traditionally, ship's wheels were large wooden structures with multiple spokes radiating out from a central hub. However, with the advent of modern technology, many ships now use smaller wheels made of materials such as stainless steel or aluminum.

3. Size: The size of the ship's wheel varies depending on the vessel. Smaller boats may have compact wheels, while larger ships require larger wheels to accommodate the force needed to steer them.

4. Mechanics: The ship's wheel is connected to the rudder through a series of mechanical linkages or hydraulic systems. When the helmsman turns the wheel, it transmits the motion to the rudder, which then moves to change the ship's direction.

5. Steering Ratio: The steering ratio determines how much the rudder moves in response to the wheel's rotation. The ratio can be adjusted as needed, allowing the helmsman to have precise control over the vessel's maneuverability.

6. Ergonomics: Modern ship's wheels are designed with ergonomic considerations to ensure ease of use and comfort for the helmsman. They often have a rim that is easy to grip, with suitable finger grips and a smooth rotation mechanism.

7. Backup Systems: In case of any mechanical failure, ships usually have backup steering systems in place. This can include emergency tiller systems, hydraulic pumps, or even remote control systems that allow steering from alternative positions on the ship.

8. Digital Advancements: With the advancement of technology, some ships now utilize digital steering systems instead of physical wheels. These systems incorporate electronic controls and joysticks, allowing precise and automated steering.

In summary, the ship's wheel is an essential component for steering a ship. Whether it is a traditional wooden wheel or a modern digital console, it provides the helmsman with the means to control the ship's direction and maneuver safely at sea.
