What type of mechanism is commonly used in shipboard steering systems?

Electrohydraulic systems are commonly used in shipboard steering systems because they offer several advantages over other types of mechanisms. These systems utilize hydraulic power to operate steering mechanisms, allowing for quicker and more precise control of the ship's rudder. By using a combination of electrical signals to control hydraulic fluid flow, electrohydraulic systems provide a responsive steering capability, which is essential for maneuvering large vessels, especially in challenging conditions such as narrow channels or during docking.

Additionally, electrohydraulic systems can integrate with modern navigation and control systems, enhancing overall operational efficiency. The automation and reduced physical effort required from the crew make these systems more versatile and safer, especially when compared to more manual systems that might require greater physical input or produce slower response times. This combination of precision and efficiency is why electrohydraulic mechanisms are favored for shipboard steering systems.
