Chain marking sequences
The below table gives recommended sequences for marking your chain with the final column showing number of colours you would need for that sequence.
The "A" for the Anchor (Red) should be placed about 1-2 meters from 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.
The "STOP" in placed near 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!)
