Hello everybody,
We know the you have to release 5:1 or 7:1 anchor chain/line depending on condition and boat.
Here is my question:
When you start dropping chain how do you know that the length you need already there (assuming that is no marks on anchor chain or line) ?
I usually do it by intuition (do not have my boat using charters) . Just curios if its a better way (speed of windlass, etc.)
If its really stupid question please answer anyway.
Thank you

The chain should in fact be marked.

But if it's not, and you want to be precise, you can do a quick test and measure how many rotations of the windless drops say 10' of chain - that's better than timing the windless because the timing can depend on how much chain is hanging down (speeds up when more chain is having in the water). Some people put a piece of tape on the top of the windless to make counting rotations easier.

That is a lucid, intelligent, well thought-out replay.
Thank you so much.

An afternoon with two cans of spray paint tied up along a shore pier and the chain is vividly marked, and will last for years. Just alternate the colors every 25 foot, and count the number of color changes as it spools out.

Bash is colorblind, so we use white primer sprayed on the chain. A small 3-link dot every 25' and then a foot-long section of white marking 50', two foot-long marks at 100', three at 150', et cetera.

I end up having to re-paint the marks every other year.

Nice thing about using white primer is that you can see the marks at night.

The hi-tech method is to use a digital chain counter.

But stumbles idea is among the best. I would add to that with - use a magic marker to write the colours and lengths on the bottom of the cover to your chain locker.

I have seen attempts to use coloured wire ties, but the windlass has a habit of eating them.

If you have three strand rope rode (warp) as well as chain, slip tags with the length between the strands.

BTW - if you are going top spray paint a la Stumble, start with a 25 length on chain on the dock and then just flake 25 foot loops of chain. Put some cardboard under the turns and spray paint them all at once.

you can tie thin threads of specra of different colours at 10m intervals

I think the OP is a charterer?

Hence (presumably) Evans' reply, which concentrated on using the gear as supplied.

Greg Fil · 18-10-2012, 13:45

You are all good. And I like your ideas. However, I am talking about situation when:
1. It's not your boat.
2. Anchor chain / line is not marked.

Thank you everybody for such a quick reply.

jackdale · 18-10-2012, 13:48

Yep - charterer. Evan's solution is great and one I had not thought of. I will be using it. Most boats I have chartered or on which I teach do have marked chain.

I have asked charter companies / sailing schools to mark chain for me.

Greg Fil · 18-10-2012, 13:57

You right they usually marked chain. But recently I was in the situation when chain was unmarked. Two times. Both times charter company. I deal with it but it's good to know what more experienced sailors do in this situation.

With experience you can get a good estimate of how much chain you have out by judging the angle of the rode when you are setting the anchor in reverse. Of course if it does set, you may have insufficient rode.

Hi,
Great advice. I have another equally stupid sounding question. For world cruising how much chain should I aim to carry. I currently have 55 metres.

100 m is a safe amount in my opinion. With coral all chain needed to be used. Coral can slice through rode very quickly.

AT 8:1 rode length, 100 meters means anchoring in a water depth of approx. 12 meters.

At 8:1 rode length and high winds, your rode will taut and you will not have a catenary. There is little benefit to using more than 8:1 as you will not achieve a catenary.

Don't forget a suitable snubber
