Permafloat Wave Defenders

Wave Defender® protects your dock from rough waves caused by boat wakes and wind. It reduces your dock’s rocking and rolling motion, thereby reducing dock wear and tear. Wave Defender® stabilizes your floating dock just as well as commonly used heavy weights but without requiring additional floatation to maintain freeboard.

It can be used with both new or existing docks, allowing you to relax and better enjoy your time on the water. Wave Defender® attenuates waves and may serve as a breakwater to protect residential and commercial floating docks.

The system is made of two special types of extra thick, double-flanged, Permafloat® shells bolted together. The top shell is a sealed float filled with expanded polystyrene (EPS) for buoyancy, while the bottom component is an empty shell that fills with about 1100lb of water. When a wave strikes, the water in the lower shell acts like a thousand-pound weight, reducing dock motion without permanent buoyancy loss.

Manufactured using tough, 100% virgin, superior grade polyethylene with UV inhibitors, these shells are 0.200 inches thick—much thicker than standard floats. The filled float has a buoyancy of 1,088lb when fully submerged.
