The Complete Guide to Buoys
Whether you're piloting your pontoon, skippering your sailboat or somewhere in between, knowing the different types of buoy markers and how to read them can help you navigate safely. This complete guide to buoys aims to give you a better understanding of how buoys and maritime markers are used to navigate, moor and regulate, why they're important and what the colors really mean.
Buoys - What are They Used For?
A buoy is a buoyant device that floats on the water’s surface, commonly used to help boaters navigate safely from place to place. Some buoys give you a sense of direction, like what side of the channel you’re on, while others communicate no wake zones, shallow water, bottom hazards and so on. Buoys can also be used to mark areas of interest, such as national parks or swimming areas
Nun and can buoys exist for the sole purpose of communicating information related to direction. A green can buoy marks the port (left) side of a channel while a red nun buoy marks the starboard (right) side of the channel when navigating in the upstream direction. If you see a buoy marked with three bands of alternating green and red, it is a bifurcation buoy. This type of buoy marks the junction point of a divided channel.
Used by boaters to secure their vessels, mooring buoys are often used in place of traditional anchors so as not to damage fragile marine ecosystems or seabeds. Additionally, mooring buoys help give boaters a visual guide when docking alongside others, minimizing the possibility of collisions. By way of heavyweight chains or ropes, a sinker is attached to the buoy and placed on the seabed, keeping the vessel in one place.
Like road signs on the highway, regulatory buoys communicate rules and alert boaters to hazards ahead. These buoys are a critical maritime tool that keep people safe while navigating open water. Often, regulatory buoys are white with orange bands or symbols and display a cautionary message for boaters. You might see these markers indicate things like no wake zones, no swimming, PWC areas, speed limits and more. Sometimes, they will have flashing lights to draw extra attention.

Specially designed for the commercial fishing industry, low-drag buoys make the retrieval of crab pots faster and safer. Low-drag buoys ease the strain on both the crew and gear, a much needed advantage in what is commonly considered the most dangerous job in the world.
Commonly found in oceans and lakes, these high-tech buoys measure and monitor things such as air temperature, wind speed and direction, wave height and more. The buoys then transmit the data collected to satellites for real time data analysis.
A life buoy, sometimes referred to as a life ring, is a flotation device that can be thrown or dropped to someone in the water. The line attached is then used to pull the person to safety. This life-saving device adds buoyancy to the distressed individual, preventing drowning.

A: Cylindrical can-shaped buoys mark the edge of the channel on your port side (left) when entering from the open sea or heading upstream.
Q: What does a red cone-shaped buoy mark?
A: Also known as Nun buoys, red cone-shaped buoys mark the edge of the channel on your starboard (right) side when entering from the open sea or heading upstream.
Q: What does a regulatory buoy with a diamond symbol indicate?
A: Watch out! This buoy signifies danger, marking areas that are hazardous for boaters. You may find these boat buoys in areas of submerged rocks or shoals.
