SAILING GLOSSARY

Radar

Radar is a device that uses radio waves to detect objects around a boat and determine their distance and direction. It can be used to detect other vessels, obstacles, land, or structures, even when visibility is reduced by fog, rain, or darkness. In navigation, it is a complementary tool to other instruments and visual observations. In short, when you can’t see much anymore, it’s reassuring to know that something is still keeping watch!
