Ahoy there, mateys! Have you ever wondered what the wheel of a ship is actually called? Well, wonder no more! The wheel that controls the direction of a ship is called a “helm.” That’s right, it’s not just any old steering wheel – it’s a helm, and it’s been an integral part of sailing for centuries.
Before modern technological advancements, the helm was the ultimate tool for steering a ship. Imagine standing at the helm of a massive wooden vessel, with nothing but the wind and your own strength to guide it. It was a true test of skill and courage, and one that sailors took very seriously. But even though technology has taken over many of the duties of the helm, it remains a crucial part of any ship’s operation.
So, why is it called a “helm?” Well, the term actually comes from the Old English word “helym,” which means “protective covering.” The helm is essentially the protective covering that shields the ship from the dangers of the sea, and the sailor who stands at the helm is the one who guides the ship to safety. It’s a noble role, and one that every sailor must respect.
The Anatomy of a Ship Wheel
The ship wheel is one of the most important parts of a ship. It is the device used to steer the vessel and keep it on course. The ship wheel comes in various sizes depending on the size of the ship it is attached to. However, regardless of its size, the anatomy of a ship wheel has remained the same over the years.
- Hub – This is the center of the wheel, where it connects to the steering mechanism.
- Spokes – The hub connects to several spokes that radiate outwards, usually about 8 to 10 in number.
- Rim – The spokes connect to a circular rim that forms the outer edge of the wheel.
- Handles – The rim has two handles, one on either side, that the helmsman uses to steer the ship.
- Keeps – These are brackets that keep the spokes attached to the rim.
Each part of the ship wheel plays a critical role in ensuring that the vessel stays on course. The hub allows the wheel to connect to the steering mechanism, while the handful of spokes that radiate out from it allows the helmsman to grip the wheel securely. The circular rim around the outside of the wheel houses the handles that the helmsman uses to turn it. Finally, the keeps keep the spokes attached to the rim preventing it from falling apart.
The appearance of the ship wheel has evolved over the years, but its basic anatomy remains the same, as it remains an essential component of the steering mechanism of a ship.
