Skrew Mooring Installation

The Skrew Mooring Anchor is a helicoid mooring system designed for multiple applications; sailboats, motorboats, floating docks, fish farms, basins, etc. Skrew moorings are eco-friendly and do not damage the sea bed. To ensure equal weight, these helicoid anchors have a higher holding capacity than any other type of traditional mooring system, such as mushroom moorings or concrete moorings.

Advantages:

  1. - For its inexpensive price, the helicoid mooring anchors' holding power is the best.

  2. - The anchor is made of hot-dipped galvanized marine steel for a long lifespan.

  3. - Unlike temporary anchors, these do not dredge on the sea bottom and do not require a great water height ration for the mooring line. They are thus respectful of the sea beds' ecology.

  4. - The "Skrew" anchor is made from high strength steel. The rod is forged of only one metal bar with a round eye fixation.

  5. - Installation is carried out using a bar passed through the eye.
