Choosing the right anchor chain<\/strong> starts with one simple step: measuring it correctly.<\/p>\n\n\n\n

Many vessel operators assume the anchor chain size printed in documents is accurate. In reality, wear, standards, and past replacements often mean the actual size is different. If the size is wrong, you may face problems like poor anchoring performance, chain jumping on the windlass, or even safety risks.<\/p>\n\n\n\n

In this guide, we\u2019ll walk you through how to measure anchor chain size step by step<\/strong>, using simple tools and clear explanations.<\/p>\n\n\n

Why Measuring Anchor Chain Size Is Important<\/h2>\n\n\n\n

The anchor chain does much more than connect the anchor to your vessel. It:<\/p>\n\n\n\n

    \n
  • Absorbs shock loads from wind and waves<\/li>\n\n\n\n
  • Keeps the anchor angle low for better holding power<\/li>\n\n\n\n
  • Works directly with the windlass and chain gypsy<\/li>\n<\/ul>\n\n\n\n

    If the anchor chain size<\/strong> does not match your windlass or anchor:<\/p>\n\n\n\n

      \n
    • The chain may slip or jump<\/li>\n\n\n\n
    • Wear will increase quickly<\/li>\n\n\n\n
    • Anchoring safety is reduced<\/li>\n<\/ul>\n\n\n\n

      That\u2019s why accurate measurement matters more than relying on nominal sizes.<\/p>\n\n\n\n

      What Does \u201cAnchor Chain Size\u201d Actually Mean?<\/h2>\n\n\n\n

      When people talk about anchor chain size, they usually mean more than just thickness.<\/p>\n\n\n\n

      A complete anchor chain size includes:<\/p>\n\n\n\n

        \n
      • Chain diameter (d)<\/strong> \u2013 the thickness of the steel bar<\/li>\n\n\n\n
      • Link length (p)<\/strong> \u2013 total length of one chain link<\/li>\n\n\n\n
      • Link width (b)<\/strong> \u2013 overall width of the link<\/li>\n\n\n\n
      • Inside width<\/strong> \u2013 critical for windlass compatibility<\/li>\n<\/ul>\n\n\n\n

        Different standards define these dimensions slightly differently, which is why real measurement is always recommended.<\/p>\n\n\n\n

        Common Types of Anchor Chain<\/h2>\n\n\n\n

        Before measuring, identify the type of anchor chain you have:<\/p>\n\n\n\n

          \n
        • Stud link anchor chain<\/strong>\n
            \n
          • Has a bar (stud) across the link<\/li>\n\n\n\n
          • Stronger and commonly used on larger vessels<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • Studless anchor chain<\/strong>\n
              \n
            • No stud inside the link<\/li>\n\n\n\n
            • Lighter and easier to handle<\/li>\n<\/ul>\n<\/li>\n\n\n\n
            • Short link vs long link chain<\/strong>\n
                \n
              • Short links are designed for windlass use<\/li>\n\n\n\n
              • Long links are not suitable for most anchor systems<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

                The chain type affects both measurement and compatibility.<\/p>\n\n\n\n

                Tools You Need to Measure Anchor Chain Size<\/h2>\n\n\n\n

                You don\u2019t need special equipment. Basic tools are enough:<\/p>\n\n\n\n

                  \n
                • Vernier caliper or digital caliper<\/li>\n\n\n\n
                • Steel ruler or tape measure<\/li>\n\n\n\n
                • Flat surface<\/li>\n<\/ul>\n\n\n\n

                  Avoid estimating by eye. Even a few millimeters can cause problems with the windlass.<\/p>\n\n\n\n

                  Step-by-Step: How to Measure Anchor Chain Size<\/h2>\n\n\n\n

                  1. Measure the Chain Diameter (d)<\/h3>\n\n\n\n
                    \n
                  • Measure the diameter of the steel bar forming the link<\/li>\n\n\n\n
                  • Avoid heavily worn or corroded areas<\/li>\n\n\n\n
                  • Take measurements at several points and use the average<\/li>\n<\/ul>\n\n\n\n

                    This is the most commonly referenced anchor chain dimension.<\/p>\n\n\n\n
