Chain dimensions form

We ask for the outer width and outer length of the chain link because it is easier for you to measure. You can submit either measurements or photos through the below form. If submitting photos if digital calipers please ensure the screen is visible.

Chain marking intervals for 70m

Chain marking intervals for 61-70m chain

We would recommend you mark

  1. with red just above the anchor so when it is about to reach the boat you can position it correctly, clean it if necessary and slow down retrieval so as not to slam it up onto the boat.
  2. every 5 meters with a different colour up to 20m for shallower anchorages
  3. every 10 meters with a different colour from 20m upwards as below

  4. with a stop sign as close to the end of the chain so the markers come out of the windlass just before the chain locks tight (assuming you have it attached to the boat!)

1 2 3 4
A 5 10 15 20 30 40 50 60

You will need a 10-position chain marking set as below
