Marking Anchor Chain

Couldn't agree more, we never use less 100ft of chain (unless very tight anchorage for short term). If there is any likely threat put out 200ft. I have frequently had about 180ft out in 30ft over sand. I have tested this and friction on the chain alone will hold us on sand and full astern with 80hp and a 3 blade prop. I read a table somewhere that suggested 80hp astern was equivalent to about 25-30 kts. Obviously very rough depending on windage etc. The chain is no use in the locker!

We mark with small lengths of ordinary white cord through separate links. one at 60ft, two at 120 ft etc. It was marked this way when we bought the boat, I guess fathoms may be the base. The cord lasts a couple of years.

We do have another single mark at about 15ft. This is very handy for indicating if the anchor has left the bottom and that the boat is adrift (signal the person at the helm to pay attention).

I use the commercially available colored rubber dogbones that insert inside the link. Defender carries them. I use two for each mark, so I can see it whichever way the chain is oriented, and if one pops out I don't misread the length. I lose about one dogbone a month which is quite acceptable and keep a bag of them in my pocket as I'm pulling up the anchor for rapid remarking if needed. I've used both paint and cable ties in the past and find these dogbones vastly outlive either solution.

Whatever you choose, double the marks so you won't misread the length after a single failure.
We dragged at Isleboro once due to misreading the marks and learned this lesson.

Advanced Cable Ties

The main purpose of a tie is to hold together a bundle of wires

I've often thought to name my next boat "Zip Tie" because without them, where would I be? Zip Ties are cheap, easy, and have lasted on our anchor chain to mark every 75ft for years! We have about 5-8 of them on and when I notice a few missing, I slap on a few more in the spot. They go through the windlass without fail but most importantly, for me anyway, they are a cheap and easy way to mark our chain.

Ditto on brightly colored large zip ties, with their long tails hanging/flopping about. We have a set of different colors every 20 feet. The best!

Tie wraps - several on different links at each interval (we do 25 feet intervals). Let the ends flap.
It makes them easy to see (you have to watch the chain go out).
Different colors help if you can remember what they mean.
Last pretty well. Easy to replace. Don't cost much. Go through the gypsy and the feed pipe freely.
