RYA Radar

Cruising boats increasingly have radar on board. The International Regulations for the Prevention of Collisions at Sea state that if you have a radar, you must know how to use it. Radar is probably the most versatile of all electronic navigation aids, but the best results are only obtained when you know how to use all the functions correctly. It is not an all seeing eye, and can easily mislead those who do not understand its controls, allow for its limitations, or interpret its picture.
