Buoy Rules and Safety
Approaching Buoys
When approaching a buoy, always reduce speed and exercise close attention. Always use the chart as your primary reference. Treat buoys as confirmation information, not the sole reference. If you detect an unusual buoy position, trust the chart and use other tools to confirm your location. Never assume that the waters are safe just because you cannot see a buoy. Proceed slowly and remain vigilant for danger. Conspicuous, highly visible buoys help identify channel markers and danger zones, especially in busy or poorly lit waters. Many ports choose durable, custom-made buoys to improve safety and reduce maintenance costs.
Responding to Diver Flags
You must know what diver flags look like and what to do when you see them:
- The Diver Down Flag is red with a white diagonal stripe. It means a diver is in the water.
- The International Code Flag Alpha is blue and white. It also signals divers below.
- When you see these flags, keep at least 300 feet away in open water and 100 feet in narrow channels.
- Slow down, change course, and watch for bubbles on the surface.
Tip: Always reduce speed and stay alert near diving areas to protect everyone in the water.
Essential Safety Tips
Follow these top safety tips for safe navigation:
- Use charts as your main reference, not just buoys.
- Slow down if a buoy is missing or out of place.
- Learn light signals and horn sounds for nighttime travel.
- Report any buoy problems to the Coast Guard.
- Take a boating safety course. Training helps prevent accidents and teaches you the rules.
Choosing high-visibility buoys can reduce accident rates by up to 25%. Stay informed and plan your route before you leave the dock.
Following buoy rules helps ensure the safety of others. Always pay attention to and remember the meaning of the buoys. Accidents often occur when crew members are unaware of the rules. In Minnesota, the number of accidents has decreased as more people have learned the rules. Choose navigation equipment from reputable, trustworthy companies. Understanding and following the rules will make sailing more enjoyable.
