Docks & Wave Attenuators

Docks and wave attenuators anchored with chains tensioned at high tide will wander at low tide when the chain becomes slack. When wind and waves build, chain-anchored structures will jerk violently as the chain becomes taut. Peak loads at the windward chain-to-dock connections can cause them to fail.

Docks and wave attenuators anchored with Hazelett Elastic Rodes (or a combination of elastic rodes and chain) are tensioned at low tide, so they stay put at low tide.  As the tide rises, the elastics stretch. Docks and wave attenuators secured with Hazelett Elastic Rodes have a more gentle motion, reduced point loads, and are easier to walk on in rough weather.
