Boat chain

mooring

In the Nordic ice conditions, the cheapest and most popular mooring way is to use a combination of concrete anchors and mooring chains. Only a sufficient water depth (1 m) and the right chain length (five times the water depth) are required. Chain mooring is designed for securing the vessel horizontally, while retaining its ability to move up and down with water. Anchors are designed as self-anchoring, and their mounting loops and reinforced concrete are resistant to seawater and to the strong hits from rocks and ice. The size and quantity of anchors is selected based on the type of substrate and the size of the pontoon. You can increase the anchor’s force by adding extra weights that are attached to the middle of the chain.
