The second syllable "helm" is pronounced with the short "e" sound /ɛ/, followed by the "l" sound /l/ and the "m" sound /m/. Altogether, this word refers to an automatic steering system used on boats and ships.
Autohelm is a noun that refers to a device or system designed to automatically control or steer a ship, boat, or other watercraft. It is commonly used in maritime contexts, particularly in relation to sailing vessels. The term combines the words "auto" (meaning self or automatic) and "helm" (referring to the steering apparatus or mechanism of a vessel).
An autohelm typically consists of a collection of sensors, actuators, and microprocessors that work together to control the direction and movement of a vessel. These systems incorporate various technologies such as gyroscopes, electronic compasses, and GPS receivers to accurately determine the vessel's position and heading. Once the desired course or route is set, the autohelm keeps the boat on track by making real-time adjustments to the rudder or sail trim, ensuring a consistent heading relative to wind or a reference point.
The advantages of using an autohelm are numerous. It relieves the helmsman from the need to constantly steer the vessel, allowing them to focus on other aspects of navigation or operation. It can also help maintain a steady course or heading, reducing the risk of human error. Additionally, an autohelm can be particularly useful during long voyages or in adverse weather conditions where the boat's stability and safety are paramount.
Overall, autohelms play a crucial role in modern maritime technology, providing automated steering capabilities to enhance the efficiency, safety, and convenience of sailing and navigation.
The word "autohelm" is a combination of two terms: "auto" and "helm".
The term "auto" is derived from the Greek word "autos", meaning "self" or "own". It is often used as a prefix to indicate something is self-operating or automatic.
The term "helm" has its origins in Old English and Middle English. It refers to the steering apparatus or mechanism used to control the direction of a ship or boat. It can also be used more broadly to refer to any type of steering device or mechanism.
When these two terms are combined, "autohelm" essentially means a self-steering device or mechanism. It is often used in the context of ships or boats to refer to an electronic or mechanical device that automatically controls the direction of a vessel, allowing it to steer itself.
