This heavy-duty inflatable buoy from North East Harbor is seriously tough! Made from marine-grade vinyl that resists sun damage and harsh weather conditions. The bright red color makes it highly visible on the water for marking locations, anchoring, or mooring. Measuring 19 inches in diameter by 25 inches tall, it's substantial enough for boats up to 60 feet when used as a fender. The 1.18-inch eyelet is reinforced for attaching ropes securely. Inflation is easy with a standard ball needle or air compressor - just don't overinflate! The sidewalls should be firm but still compress about half an inch under light pressure. With a 22.5-gallon volume, this buoy has plenty of buoyancy for its size. Perfect for marking fishing spots, swim areas, underwater hazards, or as a temporary anchor buoy. The vinyl construction is much more durable than cheap plastic buoys and won't become brittle in cold weather. Whether you're a serious boater or just need reliable markers for your waterfront property, this buoy delivers professional quality at a reasonable price. It's one of those boating accessories that seems simple but makes your time on the water much safer and more organized.
