In navigation, what does the term "bearing" refer to?

The term "bearing" in navigation specifically refers to the direction of an object measured in degrees from a reference point, typically true north or magnetic north. A bearing is expressed as a numerical value, representing the angle between the north and the line from the observer to the object being observed. It is fundamental for navigators to determine their position in relation to other landmarks, vessels, or navigational aids.

This concept is essential as it allows mariners to convey and understand the direction of various navigational elements clearly. For instance, if a vessel has a bearing of 045°, this means it is located 45 degrees clockwise from north. Bearings are crucial for plotting courses, avoiding hazards, and ensuring safe navigation at sea.
