What type of compass would you typically use on a ship?

A gyrocompass is typically used on a ship because it provides a reliable means of navigation that remains unaffected by the Earth's magnetic field. Unlike magnetic compasses, a gyrocompass uses the principles of gyroscopic motion to indicate true north, which is crucial for accurate navigation at sea. Its functionality is particularly important in maritime settings, where magnetic influences from the ship's structure and surrounding environment can cause errors in navigation.

While there are various types of compasses used for different applications, the gyrocompass is specifically designed for the complexities of marine navigation. It offers other advantages such as stability in rough seas and the ability to maintain orientation even when the vessel is moving, making it the preferred choice for ships navigating across large bodies of water.
