ELASTIC MOORING SYSTEMS — FOR YACHTS, DOCKS, WAVE ATTENUATORS, AQUACULTURE FARMS

A BRIEF HISTORY OF HAZELETT MARINE The Hazelett Elastic Mooring System is an advanced alternative to traditional ball and chain moorings. When riding out “The Hurricane of 38” and then Gloria in 1985, on two different vessels anchored with chain, Vermont-based inventor and industrialist Bill Hazelett had ample time to observe the stresses and motions of vessels anchored with chain in extreme weather. Bill Hazelett was determined to develop an elastic mooring system that would reduce point loads on deck hardware, eliminate the jerking motion when chain becomes taut and keep the vessels pointed...

PRODUCT BENEFITS Environmental Conservation The Hazelett Elastic Mooring System, connected to a block or Helix screw anchor, floats above the seabed with a minimal environmental footprint. Hazelett Marine is involved in several eelgrass restoration projects. Point Load Reductions Securing vessels with Hazelett Elastic Rodes will reduce point loads at connection points (from docks to anchors and from deck cleats to anchors) by approximately fifty percent. Wind Load Reductions Boats secured with Hazelett Elastic Rodes stay pointed directly into the wind with a more constant, gentle pull. Increased...

SINGLE POINT MOORING SYSTEMS The Hazelett Conservation Elastic Mooring System is an advanced alternative over traditional ball and chain moorings. From the anchor upwards, our system consists of galvanized hardware for attaching to the anchor or block, hard trawl floats to keep the components afloat, one or more elastic rodes, a spar buoy, and a stainless steel swivel. We recommend Helix anchors or concrete blocks for securing to our elastic rode(s) system. We stock a custom top termination fitting for 1½" Helix anchor shafts, providing the easy connection of the elastic rode to a Helix anchor....

Shellfish and finfish need eel grass for spawning and for protecting their young. However, traditional chain mooring systems destroy eel grass and other aquatic vegetation when the chain rakes the bottom with the direction changes of winds and tides. With chain systems, water clarity is also diminished when the chain stirs up sediment, blocking precious sunlight to the plants. In contrast, the Hazelett Conservation Elastic Mooring System protects the sea bed because our elastic rodes are floated off the bottom. We have had many reports on the regrowth of eel grass and the repopulation of lobsters...

DOCKS AND 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...

Instead of chain, our spar buoy is connected to an anchor by Hazelett Elastic Rode(s). The rodes are manufactured of cast polyurethane elastics with polyethylene thimbles. The design is based on over twenty years of research and development, and all Hazelett Elastic Rodes are inspected, serialized, and load tested at our plant. We recommend Helix anchors or concrete blocks to secure our elastic rode(s) system. We currently have three top terminations for Helix anchors: a fixed type (A) for a 13A" shaft; a fixed type (C) for a 1%" shaft; and a swivel type (B). www.hazelettmarine.com • [email protected]...
