Eagle Wave Attenuators

Wave Attenuators protect 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 and allowing you to better enjoy your time on the water.

A Wave Attenuator system is made of two special types of extra thick, double-flanged shells bolted together and to the underside of a dock. The top shell is a sealed float filled with expanded polystyrene (EPS) for buoyancy. The bottom component is an empty shell with holes that fills with about 1100 lb of water during installation.

When a wave strikes, the water in the lower shell cannot be quickly expelled, causing it to act like a thousand-pound weight. This momentarily increases the stability of the dock in wave action without requiring additional floatation to maintain freeboard.

Unlike concrete weights that permanently decrease buoyancy, the water-filled lower shell has neutral buoyancy. This provides a huge advantage as it does not compromise the freeboard or require the extra cost of offset floats.
