Navigational Rules of the Road Renewal Exercise

Generally, the boat approaching from your right has the right-of-way. Keep in mind, however, that vessels restricted in maneuverability have the right-of-way over sailing vessels, and sailing vessels have the right-of-way over power vessels that are not restricted in maneuverability.

In order to avoid collisions, you must know the rules of the road whenever he or she is at the helm of a boat. Nobody is born knowing the rules and regulations, so the best time to learn them is before you go out on the water.
The following is a 25 question quiz on the rules of the road. These questions were taken from a Coast Guard Rules of the Road exam that a friend of mine took for their 100 Ton Masters license. The answers are high lighted in red. You should also have a copy of the "International and Inland Navigation Rules"
to study and keep aboard your boat. Remember safe boating is alot more fun.
