I can see, now, how this could work. As long as the loop of chain is long and low enough to clear the keel. That is a good idea.

Can anyone suggest strategies to prevent it from recurring?
Thanks!
use a second anchor with a few feet of chain rode on both and it will never happen again

If you attach a snubber to the anchor chain and once deployed you let extra chain out, doesn't it accomplish the same thing?
I'm having a hard time imagining how a snubber would keep the rode clear of the keel.

Re: Anchor rode keeps wrapping around fin keel - can we prevent it?

Great idea and I'll definitely keep it in mind.

We had this happen to us while anchored on the Delaware River in '77. We anchored at 0030 off the Salem Nuclear Plant but were wise enough to set an anchor watch. At 0300 my dad woke me when the anchor line was tight as a guitar string and leading aft. We had no idea what was going on when the line suddenly parted and we were adrift in 2kt current in unfamiliar water. We got underway and sailed the rest of the night to Cape May, NJ, so it ended well. But I'm real sensitive to wind and current ever since. It's happened to us twice more over the years but we corrected the problem before we lost the anchor.

Re: Anchor rode keeps wrapping around fin keel - can we prevent it?

You all are awesome. This is exactly what I needed. Last night I wrapped soft lead ribbon around a spare zinc and slid it down the rode with a carabiner as gfh suggested (probably somewhere just under 5 lbs), and we haven't had another keel wrap yet. Thanks everyone!

Re: Anchor rode keeps wrapping around fin keel - can we prevent it?

Concrete makes a lousy weight.

The density of concrete is ~145 lbs./cu.ft.
Seawater ~64#
Lead ~709#

So if you've got one cubic foot of concrete in a pail, your net weight in sea water is about 80 pounds. If you used lead instead of concrete, you'd have a 640# weight. The lead is 8x as dense as concrete (which is largely composed of water and turns to dust when dessicated) which also means that if you use a lead weight, it will be 8x smaller than the concrete for the same weight and performance.

Scrap lead can often be had from tire stores cheaply (used to be free, but the recyclers buy it form them now) and working with it is not difficult, as long as you remember the fumes can be toxic when you're melting it.

Re: Anchor rode keeps wrapping around fin keel - can we prevent it?

I have very limited experience with kellets, but my sense is that their effectiveness at improving holding power or acting as a shock absorber is inversely proportional to the conditions that would truly require such things. A 20lb sentinel like Cap-Couillon has suggested might do more in those scenarios, but you don't need more than 5lbs just to keep your rode off your keel, and that weight is much easier to manage if that's all you're trying to do. I'm thinking of reducing mine to 2.5lbs the next time I use it, and i think it will be plenty.

Here's an interesting article with some science on the subject: http://www.petersmith.net.nz/boat-anchors/kellets.php

Re: Anchor rode keeps wrapping around fin keel - can we prevent it?

Always called 'em a sentinel myself, but same thing... Quick and easy, cheap, non rust, DIY anchor sentinel.

Empty Gal Can (Plastic.. we used an empty latex paint can)
Small bag QuikCrete or similar
Scrap of SS wire (old lifeline or such)

Mix up enough QuickCrete to fill the can (make several for Christmas gifts)
Bend SS wire into U shape and stick into can (should extent at least 1/2 depth)
Let QuickCrete cure

Weighs about 20# You can string several in severe conditions. Plastic can cushions the concrete when its rolling around in the lazarette
