Mantus Anchor Swivel Break

Now that the Mantus swivel has been in wide use for a while, have we seen any examples of that particular swivel breaking?

This is not a "have a swivel or not" question, just wondering if all the banter about anchor swivels breaking vs. actual examples of the Mantus (in particular) breaking.

Re: Mantus Anchor Swivel Break

Misleading title. 🙃

That said, we have one (nit yet installed, in box with disassembled anchor) and would like to see any responses.

Re: Mantus Anchor Swivel Break

Would like to see some actual cruisers with the Mantus Swivels in use.

They look over built, compared to the other swivels on the market.

Re: Mantus Anchor Swivel Break

I have used mine for one season so far, no issues.............But that's just one season, fingers crossed. And yes, misleading title.....should be more like "Any Mantus swivel issues?"

Re: Mantus Anchor Swivel Break

How about a recent report of any respectable swivel breaking.

Would you recommend a small length of chain, maybe one foot separating it from the anchor with this swivel?

Re: Mantus Anchor Swivel Break

I made the title specifically misleading It worked!

We have a Mantus swivel that we have been using for about a year now. We have been anchored since October, with no time spend in a marina. So far, we have no issues with the swivel except that its really important to use several separate seizing wires lengths instead of one big one. We used two separate ones when we first installed it and one broke, maybe it got caught on something. We switched to using four individual lengths and we examine it carefully after we bring it up. I would think that a better solution would be a bolt that runs through where it can sit flush with the swivel casing.

NO.

The Wasi Swivel is far stronger than any shackle on the market. One of the major reasons of having a robust swivel is to eliminate all shackles on your rode. This swivel allows for you to concentrate your maintenance on the chain, not the shackle.

Are you sure that's stronger than a shackle? Considering that long lever arm? I would be pretty surprised -- do you have any actual data?

Even Kongs, considered by many to be the best, have been reported to break.

The swivel is likely to be the weak link in your ground tackle. I like the looks of the Mantus one though.

Why put data? Your observations have your mind made up.

Re: Mantus Anchor Swivel Break

I don't think I could break my Mantus swivel, reason is the way its constructed, you just about can't get a side load on the thing.
The next weak link is the pin, which on the Mantus is oblong to give the most possible area.
If it has a downside, It may be that it may not fit through some rollers, its not a small thing.

On edit, who was it that said, give me a long enough lever and a fulcrum and I'll move the world?

My mind is always open to facts, and I was the first one to say that I do NOT have any data.

Yeah, it certainly wouldn't fit through my bow roller, so my curiosity is strictly of the idle kind.

But I don't need a swivel at all since switching back to Spade from Rocna. The Spade is ballasted and really well balanced, and comes up the right way around. My previous 121 pound Rocna was balanced to come up backwards, and was not usable without a swivel. On my boat anyway. YMMV.
