What is the primary function of a ship’s compass?

The primary function of a ship’s compass is to determine the cardinal directions, which includes north, south, east, and west. This is fundamental for navigation as it helps the crew understand their orientation relative to the Earth’s magnetic field. Knowing the cardinal directions is essential for plotting a course and ensuring that the vessel is heading in the correct direction.

While measuring the speed of the ship, navigating through weather patterns, and tracking the ship’s inventory are all important aspects of maritime operations, they are not functions of the compass. The compass specifically serves the purpose of providing directional guidance, which is critical for safe and effective navigation at sea.
