Information Buoys: Squares provide information such as places to find food, supplies, and repairs. They also give directions, distances, and other non-regulatory information.
Hazard Buoys: Diamonds warn of hazards such as rocks, shoals, or turbulent waters. Always proceed with caution and keep a safe distance. Never assume that every hazard will be marked by a buoy.
Control Buoys: Circles indicate a restricted boating area such as no wake, idle speed, speed limit, or wash restrictions. You must obey the restriction inside the circle.
Keep-Out Buoys: Crossed diamonds indicate areas where pleasure craft are prohibited such as dams and spillways.
A special purpose buoy is primarily used to indicate an area or feature, the nature of which is apparent from reference to a chart, Sailing Directions or Notices to Mariners. ( UKHO NP 735, 5th Edition) Buoy in general: A buoy whose appearance or purpose is not adequately known.
Control Buoys: Circles indicate a restricted boating area such as no wake, idle speed, speed limit, or wash restrictions. You must obey the restriction inside the circle. Keep-Out Buoys: Crossed diamonds indicate areas where pleasure craft are prohibited such as dams and spillways.
BOATS KEEP OUT: This buoy is signified by a cross in the center of an open diamond. Boats Keep Out buoys mark areas where vessel operation is prohibited. Typical areas for these buoys are swim beaches and dams. DANGER: This buoy is signified by an open diamond.
An information buoy is white, with an orange square symbol on two opposite sides, and two orange horizontal bands, one above and one below the square symbols.
Special marks may be used as lateral marks. If they have a can-shaped or cone (triangle) buoy, pass them as you would a lateral mark: can: port mark. cone: starboard mark.
They are white with two horizontal orange bands and an orange circle on two opposite sides. Inside the orange circles will be a black figure or symbol indicating the restriction.
In order for the buoys (and your boat) to stay in one place, a complicated and robust anchor system lies below. There are three types of anchors commonly used in the Florida Keys to secure the buoys to the seafloor: pin anchors, u-bolt anchors, and Manta Ray® anchors.
Ocean buoys measure a whole range of weather variables such as wave height, swell period and direction, wind speed and direction, air and water temperature, and barometric pressure.
Hazard buoys or markers indicate random hazards such as rocks and shoal. A hazard buoy is colored white with an orange diamond on two opposite sides and two orange horizontal bands. Not all shallow areas or submerged hazards are marked by a hazard buoy.
Isolated danger buoys are pillars or spars that are black with a red horizontal band. They are located on or over an isolated danger, such as a rock, and may be passed on either side. Navigable water is located all around an isolated danger buoy.
An isolated danger buoy serves to mark an isolated hazard that has navigable water all around it. The dangers may be natural in origin, such as shoals, or man-made, such as shipwrecks.
Compare the above experience to a basic, anchored buoy. A buoy still bobs up and down like a float but there is no fear of it drifting to shore or away from its starting point. It is designed with slack in the chain that holds the buoy, but for consistency in it's purpose, the buoy must stay close to its anchor point.
Green or red reflective material is used only on marks which, if lighted, would exhibit a light of that color. Yellow reflective material is used on special marks and on Intracoastal Waterway marks. No significance is attached to white reflective material.
There are two international Buoyage Regions A and B where the lateral marks differ. In Region A starboard buoys are green and port buoys are red. In Region B the colours are reversed, starboard buoys are red and port buoys are green.
The IALA Buoyage System is a worldwide standard sea mark system used in navigation to mark the edge channels. These road signs on the water are made up of five buoy types- cardinal, lateral,isolated danger, special and safe water marks.
