Probably goes without saying but…Make sure your chain match your windlass gypsy.

The chain that Bob mentioned earlier “1/4” ACCO ISO G43 (G4)1/4” chain” is what I have on our Lewmar H700 windless, so it will fit yours.

Thanks for the alert. Yes, I went with chain and rode type/size that Lewmar recommended.

For those concerned with vessel weight forward and if the goal is to increase bottom
holding, another option, in stead of adding more chain*, is to increase the size of
your anchor.

* 1/4" chain weighs about 0.75 lb/ft; add 20 ' of chain to yours = 15 lbs more weight

Increase anchor size for about a 23' boat:
Rocna 6 Kg anchor weighs 13.3 lbs; holds about 4K lbs
Rocna 9 Kg anchor weighs 19.8 lbs ; holds about 13K lbs

Therefore, the difference of 6.5 lbs more anchor weight may have 9K lbs of
holding power vs an unknown extra 20' of chain holding power weighing about
15 lbs.

Aye.

50' of chain is nice to have on the Columbia if you're fishing. with that chain you can have that anchor on a short leash when parked in hog line. be sure to rig your anchor to break away. Here's a video on rigging a break away, he's using one zip tie, you need at least two to center the chain on the shank so it doesn't get hung up on the bow roller when retrieving.

I've seen this method a few times and wonder how well it works. Any chance that in heavy seas or a heavy blow that the zip tie could break off? Especially if the wind changes directions, blowing the boat back over the top of the anchor, so that the anchor line ends up pulling across the anchor and rather than the anchor resetting, the zip tie breaks?

a pair of heavy duty zip ties hold pretty good for most applications. In AK where we regularly anchored in 200' of rough water we used gangion with several wraps

My all-time favorite knot from Boy Scout days. Thank you for sharing your knowledge Bob!


Thank you.

Yes, the "taut Line hitch" stems from my Boy Scout days also.

The "breakaway" anchor rig shown in the YouTube video is intended for day use only. Unless you wish to trust your fate to the strength of zip-ties.

that's why you use gangion for heavy duty applications

I guess I'm not understanding this setup? I thought it was designed for easier breakout of a stuck anchor? If that is the purpose, then anything significantly weaker than your main rode would in theory increase your risk of failure under full strain, and (as was mentioned earlier) tend to impede a re-set of the anchor. I've seen this setup many times, but always with the warning not to use in foul anchoring weather, especially at night, when not under continuous watch.

My personal thoughts are: when do deployed anchors tend to fail? Pretty much always in a heavy-weather situation under strain, and pretty much always when one's boat is near rocks, other boats, the shore, etc.

I've heard this setup called a "fisherman's anchor"

Maybe it warrants another thread, such as: "anchor failure experiences and lessons learned" ?
