Show Written by: John Maguire Buoys are navigational devices that float on top of the water. Boaters will find and use buoys on rivers, lakes, intercoastal waterways, and the open ocean throughout the world. Some buoys are equipped with lights on the top, but others do not have lights. Buoys also come in different shapes. A buoy with a conical top is known as a "nun," while a buoy with a flat top is called a "can." Another type of navigational device that may be found on the water is known as a beacon. Beacons are permanently fixed, usually to the floor of the body of water. Beacons may have lights, but some do not. Those beacons without lights are called day beacons. When navigating the water in a boat, whether it's a large sailing yacht or a small fishing boat, you need to learn the nautical information communicated by buoys and beacons. This information is provided to keep boaters safe from harm and to help them avoid potential issues that might lead to accidents or property damage. What Are Buoys?

Types of Buoys and Their Uses
Navigational Signals From Buoys
How do you follow red and green buoys?Basically, red marker buoys should be on your right (starboard) as you return from open water. Conversely, green channel markers should be on your starboard side as you head out into open water. The red marker buoys also have a triangular shape.
What are the 5 types of buoys?These road signs on the water are made up of five buoy types- cardinal, lateral,isolated danger, special and safe water marks. These buoys and marks indicate where safe water lies and where you should navigate safely within a channel. Always refer to a local chart to identify where potential hazards may be.
What does red and green mean on the water?A green can buoy means pass to the right, and a red nun buoy means pass to the left when moving upstream. A diamond shape with a "T" inside it on a buoy means "keep out."
