In keeping with our commitment to marine sustainability, our recommended method of anchoring is with ground anchors and elastic rodes. This combination is the most environmentally friendly method available. The footprint of the anchors on the seabed is minimal, thereby causing the least possible damage. The elastic rodes are always taught and never touch the seabed – unlike chains which scour the seabed killing all growth within their scope .

| Helix Mooring Systems introduced Helix anchors to boat owners, harbormasters, and marina managers in 1992 as an alternative to traditional mushroom, deadweight, and pile anchors. In contrast to traditional anchors, these environmentally sensitive Helix anchors offer high holding and long-life. |
| High-Holding |
Our anchors derive their holding from the soils into which they are screwed. The Square Shaft anchors are installed with the aid of hydraulics to screw the anchor through resisting soils. Our anchors have been repeatedly tested by Mother Nature and tugboats with load measuring equipment.
The results of the first test (performed in Vineyard Haven, Massachusetts, under the watchful eye of area harbor masters, a marine industry reporter, and a representative of Boat/US) are typical of all the load tests performed. |

| Sizing of Anchors |
| Helix anchors can be sized according to your holding requirements. Typically, the soil and holding requirements dictate the number of helices and length of the anchor. Each helix plate acts as a separate anchor, using the soil above it to achieve holding power. |
| Long Life |
| Our high-load marine anchor is built on a solid, square shaft measuring 1 ¾” on a side. It is protected with hot-dipped galvanizing, and the termination includes a 1 1/8” shackle which encircles the shaft and connects to the anchor rode (elastic rode, chain, rope, and cable have all been used successfully). |
| Environmentally Friendly |
| Because these anchors don't drag around the harbor bottoms and can be effective with shorter scopes, they are preferred in environmentally sensitive areas and have been recommended by some state agencies and scuba-diving tour companies. |

| Hazelett Rodes |
 |
Hazelett Marine Elastic Rodes are in use in many parts of the world for anchoring docks, buoys, and marinas.
Many years of research have gone into their development to produce a product which is not only eco friendly, but can withstand the rigours of the marine environment.
The requirements for anchoring any structure are calculated carefully and the number of rodes and their placement is decided accordingly. It is possible to add more rodes to an assembly to ensure the correct elasticity, stability and strength for each installation.
Rodes can be placed individually or in multiple assemblies of 2,3,4 or 5 depending on the conditions.
They can be placed using concrete blocks or ideally in conjunction with Helix Anchors.
Majestic Jetties & Marinas is the regional distributor for these products and will be pleased to provide full information and quotation on request |
