What is indicated by the term "turn to" in maritime communication?

The term "turn to" in maritime communication specifically refers to a command to change course. When a helmsman or navigator is instructed to "turn to," it typically means to alter the vessel's direction in a specified manner. This directive is essential for navigation and maneuvering a ship, allowing it to avoid obstacles, adjust course for current conditions, or follow a predetermined route.

The other options provided do not align with the maritime context of "turn to." An order to begin work relates more to tasks or procedures rather than altering the ship's heading. A request for assistance indicates seeking help, which is a completely different type of communication. A signal to hoist sails pertains to sail handling, relevant to wind-powered vessels, but it does not convey course changes. Understanding the specific implications of maritime commands enhances safe and effective vessel operation, highlighting the importance of precise communication in navigation.
