Chain and Rope Splicing

How to Guides

The chain splice securely attaches a three-stranded rope to an anchor chain using a modified eye-splice to allow the rope to follow the chain over the windlass and into the chain locker without tangles.

This method of joining is designed to minimise chafe between rope and chain, but as a matter of prudent seamanship, it should be checked regularly and remade if there is any evidence of wear.


To prevent chaos, burn the three ends and wrap the rope at the correct length. For seven tucks, measure at least 21 times the rope's diameter and wrap the rope with tape or a Constrictor Knot tied in twine. Unravel the strands back to the tape or twine.

Practical Aspects

As when making the Eye Splice, keep each end as neat and tightly wound as possible - at least for the first three tucks. After the first tuck is completed for all three stands, the wrapping tape (or the constrictor) should be removed so that the splice can be tightened against the chain. Remember to twist each tail tightly before pulling on it!


  1. Tape the three strands of the rope together using masking tape.
  1. Unravel enough rope for approximately five to seven tucks.
  1. Pass the strands into the chain - one strand one way through the chain and two strands the other way.
  1. Splice each strand back into the standing end of the rope.
  1. Repeat for the second set of tucks, and the third and fourth.
  1. Use five to seven sets of tucks for security.

And there you have it - a successful chain and rope splice ready to use with your anchor and windlass!
