Polyform A-4 Buoy 20.5" Diameter - Red

The Polyform A-4 Buoy 20.5" Diameter in red is the industry standard for marking mooring fields, anchoring systems, and navigation hazards in open water. Born from decades of marine engineering, this all-purpose buoy has earned trust among commercial fishing operations, charter captains, and serious recreational boaters who depend on reliable gear marking in heavy seas. The signature blue rope hold and proven durability make it the go-to choice when conditions demand dependable visibility and secure attachment points.

Constructed from durable marine-grade materials, the A-4 delivers exceptional flotation and stability even in adverse conditions. Its 20.5-inch diameter provides substantial freeboard and high visibility on the water, while the integrated rope hold design allows secure, chafe-resistant attachment without additional hardware. At 9.8 pounds, this buoy offers a balanced profile that resists drift while remaining manageable for single-operator deployment and retrieval. The bold red color meets USCG standards for daytime visibility and is instantly recognizable in any water condition.

This buoy works best for marking tackle boxes, nets, trap lines, and anchoring systems in salt water and freshwater environments alike. Experienced boat operators use the A-4 Polyform buoy to prevent snags, mark shallow obstacles, and organize mooring fields with confidence. Whether you're running a commercial operation or maintaining a private mooring field, this time-tested design integrates seamlessly with standard rope and hardware. The red finish complies with maritime marking conventions and ensures your gear stays visible in fog, rough seas, and low-light conditions.
