- I installed this Mantus Anchor swivel about 1 year ago and it has been underwater almost every single day of that year. In this video we take the swivel apart and see how it is holding up in addition to inspecting the chain it is attached to see if there is any significant corrosion and if it was accelerated by the dissimilar metals touching. This is the Mantus Anchor swivel we have: amzn.to/32PXbto

I like the way you get to the point and can't believe your followup after a year. fantastic.
You guys were one storm away, from being on the rocks in the middle of the night.
Seeing your anchor chain tells me that an inspection of it, should take place every month. If not more...
I have a 30kg/65lb. Mantus anchor, swivel and bridle; all are excellent (I also have the Mantus dinghy anchor ). At this point, I will only purchase Mantus anchor products, which are really well thought out and crafted. My Mantus holds my 50' MY in place and has never dragged. In changing winds, the anchor resets immediately. Ultra anchors are great too, but they are only SS, so very expensive.
Thanks for the review.
Bravo! Great vid & analysis. Clear and thorough. Loved your comment about dirty hands! WELL DONE - Fair Winds…
I have been wondering about this for a while.
I would have thrown that chain away for years goo, bur im impressed with the Mantus Swivel
Great review, and i already have a 30 lb something as my storm anchor and a 17 lb mantus as my regular anchor. I also use the mantus swivel. Don't forget guys to use monel wire for tying everything together. You can request extra monel from mantus when purchasing. Love the Mantus anchors. I sail a 30 ft trimaran named Quetzal. It is a 30 foot Condor performance boat.
My wife said that’s what mans hands are supposed to look like.
I would have thought you would get more corrosion on the first link. So this was very informative. That corroded chain is toast. I assume you got rid of it by now. You have to re-galvanize your chain from time to time before it gets that bad. It looks like your anchor is corroding just a bit near the stainless shackle. But the anchor is pretty thick so maybe not much of a concern.
Caught up! 👍🏻.
Interesting & enlightening ⛵⛵⛵⛵⛵
Thanks for the video. Researching anchor swivels and your experience is great to see. Not sure if you are aware of Tef-Gel but it's an amazing stainless antigalling and anti corroision lubricant. I use tef-gel liberally. I kept thinking as you were pulling the teflon tape off how I would have just coated all the surfaces with tef-gel. Admittedly the teflon tape doesn't get all over your hands like a paste but that's not an issue, right? ha you got a new subscriber.
I was going to be that guy that says Billy needs a manicure. Lol
It's the zinc with which the chain is galvanised which would 'disappear'
the teflon tape is for preventing galling of the SS, which means the threads will cold weld and then you can not get it apart.
Eric is right you must get rid of that corroded chain. It is a boat killer in its weakened state. If you cannot replace it immediately you might consider cutting the chain down to the longest length of uncompromised links and then add rope to provide a sufficiently long overall rode. Will's earlier comment about chain vs. rope is interesting but the argument for chain might have less to do with modern material strength than the chain's advantage of strength and overall weight spread along the rode's full length which has a dampening effect. Also, in crowded anchorages where most boats use chain rodes a boat using a longer length of nylon and chain is going to be a lousy neighbor. In fact it could get ugly, don't ask me how I know.
I wonder how the teflon tape would hold up as a barrier to the dissimilar metals? Thoughts?
I don’t think it’s “dissimilar metal” diameter loss, rather than link to link friction at tension. Your thoughts?
Good segment.. predicting corrosion IS an art. I never thought about it, but would some kind of sacrificial zinc attached reduce chain link loss I wonder? Maybe a second life for old zincs..
Galvanized chain is coated with zinc.
This chain is only 2 years old? What was the quality of chain when you bought it? Is it US made?
Aaahhhhhhhhhh replace it now!!
Shoestring living is no fun!
What happened to the locktite that you used on the threads when you originally installed it? The threads look clean?
ha! That's what I was wondering too...
This Mantus Swivel is money well spend (spent?? - not sure about the correct spelling, sorry) when your house depends on it. Some sturdy metal work!
A good quality stainless chain is a pretty good investment. It last a good while longer than galvanized. You can of course re-galvanize...
I believe the stainless chains don’t have as high working load like galvanized.
@@SailingPauHana Probably not, but I'm sure they would be close enough. It depends on where they come from and the grade. There is some great German chain out there for instance, but the Chinese chain is garbage.
Allyn Onderdonk totally agree. We are now in the process of researching and buying chain. China chain is trash. The chain we have now is Italian and awesome..it’s just too short.
Sailing Pau Hana Italian Stallion Chain, Yo Adrian !!! LOL 😂. I watched Gone With The Wynn’s and they bought a second grade level chain and in several weeks it was totally rusted and corroded, they even announced the name of the chain and company because they would not give them their money back or replace the chain. Buying the best chain and anchor is the only way to go even if it sets you back for a year, your boat and your lives depend on it. Good luck. Stay safe.
VonBluesman do you recall the name of the company that sold the junk chain?
For pete's sake Billy....Wash your hands!......LOL :-)
the tape is just plumbers tape available at any plumber or hardware store
I am wondering if the windlass is causing more wear and tear on your chain than the corrosion underwater.
Thanks for this excellent video! I suppose the conceptual reason for adding a swivel is to help keep twist out of the anchor chain. However in some testing done by Practical Sailor they concluded that there is "no convincing reason to add a swivel to an anchor setup" because they don't really do much. Therefore, assuming that their testing is valid, it would seem that introducing this additional element is only creating places for a failure to occur with little benefit.
They actually recommend adding a short piece of chain between the anchor and swivel to avoid side loads that cause swivel failure!
On my boat I use chain only with oversized shackles!
I prefer to trust in the Rocket science of Mantus than the peanut gallery of lazyboy armchair wanna be sailors.... the swivel always flips the anchor into the roller at the proper angle and the anchor always holds 1st time I set it!
Chain is the problem!!! Most is China junk.....
@@fredbrillo1849 no mantus doesn't....
Just opened the Mantus on a boat we recently bought. The last link is badly rusted. I expect the tight tolerance wore off the galvanizing. I also discovered the anchor will not flop over when it enters the roller only because the groove in the center of roller grabs the shank. I'll lose the Mantus and add a roller without the groove like I've had on all my previous boats.
That's generally a good rule of thumb, but here's why I went with the Mantus: There are important benefits to consider not discussed to any significant degree in the testing, which surprised me: For example, I have seen and experienced that without a swivel the chain can become twisted, so that when droping, a twist can cause the chain to get knotted as it runs out of the spurling pipe. And when weighing, a twisted chain can become folded on itself on the way up, jamming in the roller or jumping off the gypsy chain wheel. In either of those cases you now need to release a chain knot under load, often while drifting. Once this happens a few times when you're coming or leaving in a blow, it's an easy choice to consider a proper swivel, properly installed, maintained and inspected.
You should really clean your hands, don't wanna keep getting the boat dirty....
