Which of the following is a common type of ship control system?

• A. Manual
• B. Automation
• C. Hybrid
• D. Electric

Answer: (B)

Automation is a common type of ship control system. It uses sensors, controllers, and actuators arranged in feedback loops to monitor conditions like course, speed, and engine parameters and automatically adjust controls to keep the ship at the desired state. This enables autopilot for steering, automatic throttle or engine speed control, and an integrated bridge that coordinates propulsion, steering, and navigation with minimal human input. The result is more consistent performance, quicker responses to changing conditions, and reduced crew workload and potential for human error.

Manual control relies entirely on a person at the controls, which is less common on modern vessels due to the higher workload and slower reactions. Electric describes how power is delivered to actuators rather than a control philosophy, though electric actuators can be part of automated systems. Hybrid systems exist, combining automation with manual input, but automation remains the most widespread approach.
