what do you call the steering wheel of a ship

The steering wheel of a ship isn't actually called a steering wheel! While it looks similar in function, the correct term is a helm. This article will delve into the history and mechanics of the helm, exploring why this specific terminology is used and what other related terms you might encounter.

The Helm: More Than Just a Wheel

The helm is the primary control used to steer a ship. While modern ships often utilize sophisticated electronic systems, the fundamental principle remains the same: the helm's movement translates into directional changes for the vessel. Think of it as the brain of the ship's navigational system, receiving commands and directing the rudder.

A Brief History of Helmsmanship

Early ships relied on simpler steering methods, such as large oars or rudders controlled by ropes and levers. The evolution to the wheel-like helm we're familiar with wasn't immediate. The transition to a wheel-based system significantly improved control, particularly on larger vessels. The introduction of the helm made steering more efficient and less physically demanding, enabling the precise maneuvering of larger ships.

Types of Helms

While the visual image of a large ship’s helm often brings to mind a traditional ship's wheel, modern ships utilize various helm systems.

Mechanical Helm: This involves a direct mechanical connection between the helm and the rudder. Smaller vessels often use this simpler system.
Hydraulic Helm: This system uses hydraulic pressure to power the rudder. This allows for easier steering, especially in larger ships.
Electro-Hydraulic Helm: This is the most common type in modern, large vessels. It combines the power of hydraulics with electronic control, allowing for automated steering features and enhanced precision.

Related Terminology

Several terms are associated with the helm and the process of steering a ship:

Helmsman: The person responsible for operating the helm.
Conning: The act of directing the ship's course. The captain might "con" the ship, giving instructions to the helmsman.
Rudder: The underwater structure that actually turns the ship. The helm controls the rudder.
Steering Gear: The entire system of components involved in steering, including the helm, linkage, and rudder.

Why "Helm" and Not "Steering Wheel"?

The term "helm" carries a richer history and more precise nautical meaning. Using "steering wheel" is technically incorrect within the maritime context. While visually similar, the term "helm" encompasses the entire steering mechanism and its function, not just the physical wheel itself.

Conclusion: Mastering Maritime Terminology

Understanding the correct terminology, such as referring to the ship's steering apparatus as the helm, is crucial for clear communication within the maritime world. So, next time you see a ship being steered, remember that it's the helmsman at the helm, controlling the rudder and guiding the vessel safely to its destination. Using the correct term showcases knowledge and respect for nautical traditions and precision.
