Manus swivel
« on: January 14, 2019, 12:39:57 PM »

Thinking about putting a mantus swivel on my 5/16 chain and 32lb bruce anchor.  The rep at mantus recommended the S1.
Appreciate any thoughts about the product and size.
Thanks,
Paul

There will be lots of opinions on swivels... almost as contentious as subject as anchors.
My opinion; skip the swivel.  It's an unnecessary complication in the relatively simple anchor system.  Before buying, I would ask myself "what problem am I trying to solve?"   If a swivel solves the problem or gives you a sense of satisfaction, go for it.   :thumb:

Hi Dave, the minor problem that i am trying to solve is:  When I pull up the anchor(by hand) it wants to spin when it clears the water.  I thought maybe a swivel would solve this problem.
Stay warm.
Thanks,

Hi Paul!
The only swivel, I find out, will work for what you want to accomplish (BTW. same issue) is Anchorlift, anchor tunrer kit. I have installed and it really works with my Rocna 15 kg. No regrets. :clap. 5/16 chain. Price little steep at $183. It works! No more annoing/dangerous, reaching for chain to twist to right position!

Hi Paul,
I can certainly see the benefit of the Anchorlift that Gregory has identified in his post above.  I have a windlass so the chain generally comes up straight and if there has been any spinning of the anchor, it rights itself once it’s off the bottom.  Lifting by hand as you do would make it more difficult to ensure the chain comes up and is deployed straight in my view. However, maybe at the beginning of the season, you could lay the chain out on the dock and carefully haul it into the anchor locker making sure there are no rotations in the chain.  This wouldn’t guarantee a whole season’s worth of trouble free retrievals but it would be a good start.
If you do go ahead with a swivel, have a look at the Practical Sailor writeup in the Sept 2015 edition; especially with regard to the recommendation to not connect the swivel directly to the anchor but have a short lead to prevent side loading of the swivel.

Good luck in your research.
Speaking of shiny boat toys, the Toronto Boat Show starts this weekend and I’ve left lots of room on my credit card for boat “necessities” that I haven’t even thought of yet! :D

I got the S2 Mantus swivel with 5/16 chain and a 45lbs Mantus. I know the website mention that the S1 and S2 would be the proper size for 5/16 chain. I only decided to go with the S2 because we have plans to do extensive cruising, living at anchor every single day and the working load/breaking strength is stronger than the chain. I'm sure it would help to solve your issue, a lot of old school guys will try to tell you they are the weakest link of your chain but that isn't true anymore.
