Anchor Chain Cable in Peter I Island, Propeller Performance Optimization - Anchor Chains

Anchor chain cables are heavy-duty chains used to secure ships to their anchors, providing stability and strength. They are designed to withstand harsh marine conditions, including corrosion and high tension. Typically made of high-grade steel, these chains ensure reliable mooring and anchoring for vessels.
