A calibrated galvanized chain is a high-quality anchor chain specifically designed for boats, offering strength, durability, and corrosion resistance. The term calibrated means the chain links are manufactured to precise, uniform sizes, ensuring smooth operation with a windlass. Galvanization provides a protective zinc coating that prevents rust and extends the chain's lifespan, making it ideal for marine environments. This type of chain is crucial for anchoring, as it adds weight to the anchor setup, improving holding power and stability, especially in rough waters. It is available in various thicknesses and grades, with higher grades offering increased strength for larger boats and deeper anchorages. Regular inspection and maintenance help ensure its longevity and reliability.
