Polyform A4 Buoys 710mm (L) x 550mm(D)

The Polyform Norway A4 Buoy is a large, ultra-durable marine buoy engineered for heavy-duty mooring, marking, and flotation applications where strength, reliability, and long-term performance are non-negotiable. Manufactured in Norway to exacting standards, the A4 buoy is constructed from Polyform’s proprietary marine-grade PVC, delivering exceptional impact resistance, superior UV stability, and outstanding structural durability in the most demanding marine environments.

Built with seamless, one-piece construction, the A4 buoy is pressure-tested to ensure consistent performance under substantial load. Its thick, reinforced walls provide excellent resistance to abrasion, compression, and punctures, making it significantly more robust than lower-grade alternatives. Unlike inferior buoys that soften, distort, or degrade over time, the Polyform A4 is engineered to retain its shape, strength, and buoyancy season after season—even in high-stress conditions.

The Polyform A4 buoy is ideal for heavy-duty and professional mooring and marker applications, including:

• Mooring larger yachts, workboats, and commercial vessels between 46-60ft

• Marking anchor lines, channels, hazards, and navigation points

• Supporting heavy floating lines, nets, and marine infrastructure

• Commercial marine, aquaculture, and industrial use

Featuring a moulded-in rope hole, the A4 buoy allows for secure, reliable rigging without the need for additional hardware. This integrated design reduces potential weak points while improving overall handling, durability, and ease of deployment in real-world marine conditions.

Available in a range of high-visibility colours, the Polyform A4 buoy ensures excellent visibility on the water, enhancing safety and identification in all light and weather conditions. Whether used in busy harbours, exposed coastlines, or offshore environments, this buoy delivers dependable, long-lasting performance you can rely on.
