Anchor swivel - Red or Blue Loctite?

You can buy the Crosby G-209A Shackles in lots of places.

This is why we post this information on the CF so everyone can be SAFE.

Defenders Marine carries them.

So my question is how many of you actually have special shackles that are as strong as your chain? I use 3/8" HT chain and it seems like to get anything to fit other then the fancy swivels gives me less strength at that point. I do understand all the concerns but even if the swivel breaks at some fraction of it rated strength due to some particular pull angle, etc it seems that it still is comparable to the usual shackles you can buy in the usual places.

Jim to get the really big shackles to fit you just use the Dremel to widen out the holes in the chain link! Duh! ;-). Lol JK.

For what it's worth in the no swivel camp. I do that have my windlass installed yet but will have my internal debate the first time I come across these alien induced twists. Do you find the more often you traverse the Bermuda triangle the more you get these twists? What about UFO sightings and the discovery of twists soon after? Maybe these are the nautical equivalent to crop circles! Lol

Try this with a steel anchor and chain:

DOH! Exactly the idea I had in mind!

Thanks!

I remember ordering chain with a "connecting link" on each end that allowed the use of a larger shackle. Is this not available on the G70 chain?

~ $15.00

I used Defender since they sold them. I assumed it was a reliable source of info: I see I didn't get the "A" rated shackles in my search. Thanks for the link.

Stupid easy to heat it up with a cheap propane torch too to remove it.
I have one of those swivels, I am very un-impressed with it. I replaced it with a Mantus swivel, which I am real impressed with, I am sure there are other good ones too, just not the one you picture.

Are you sure you are taking about a Wasi and not something else??

The Wasi has small grub screws to stop pins unscrewing. It is completly reliable and very strong. For example, a side load on a wasi will always bend the shank before splaying the forks on the swivel. Its stronger than the chain.

Its not cheap and costs maybe more than 200 Euro, however it is Lloyds certified which does say its been well tested.

I took the chain off my secondary/kedge rode over a year ago, replacing it with a 20-foot over strnegth Dyneema leader, as a part of some testing. There are a few advantages, unrelated to strength:

• Lighter to row out.
• No chain to scrape the decks.
• Sets deeper than chain.
• Fortress anchors set better in very soft mud without chain (the chain drags the shank down into the mud, tilting the flukes up--this is why they sometimes suggest an initial light set at short scope).

Though we worship chain, perhaps it isn't always needed.

• A kedge is not subject to cutting.
• Dyneema can be over strength.
• Dyneema can be covered with a free-floating chafe guard, making it very cut resistant.
• Anchors set in a V do not saw on the bottom, hence little cutting risk.
• I primarily only use a second anchor in very, very soft mud. No cutting.
• The cover makes the Dyneema easy to cleat for break-out.
• Chain catenary makes very little difference to a Fortress anchor once well-set in mud--the anchor is well underground, along with 10 feet of rode.

So far, no wear. My main rode is all-chain and will stay so.


Although it looks as though the cover could slide up, remember that chafe is coming down the rode as the anchor sets. The cover has no tendency to slide up the rode--there is nothing to pull it. At most, it bunches up around a friction point, providing more protection. The upper end is not attached, so it floats. The cover is 20 feet long.

Turns out Blue Locktite was the right choice for a bad reason. After a 7 day passage from New Zealand we anchored just off the wharf in Lautoka, Fiji as directed by Port Control to wait for Customs. Long story but they never came and we needed to move. The anchor was stuck solid in old port junk. I eventually had to get out the Hooka and hand dig the thing out. The swivel took a beating in the process. The forward tangs of the swivel bent. It didn't fail, but it isn't usable any more.
