The swivel in its various forms has come under scrutiny here before, a good deal of the comment was negative, especially regarding so called "anchor connectors". Before ceasing to be a TF member, Australian anchoring exponent Djbanji expressed the view they were essentially unecessary except for long periods of anchoring with directional reversals, and that they can, and do fail and ought be removed from a rode.
Even so, I`m sure publicity about a new Mantus product will inspire some interest.

If properly attached and of common design they are not any more prone to failure than anything else in boating.


I disagree that chain twist only occurs during long periods, it can happen everytime the chain twists in the chain locker while falling in and goes back over not under strain.


Without a roller grove it seems to happen every time I anchor.


I am definitely looking into a groove though not sure my roller can be cut so a whole new one may be required on an outdated system.


Its tough here if you always think you are correct or an expert in an area that has so few "correct" answers.

I must say, I persevered for years with a swivel, because it was there, and even bought one of those expensive ones with recessed bolt heads, but it was when it came time to end for end the chain, to bring out the nicer galvanised half never used, I found those recessed bolts cease up so hard the Alan key just stripped out and in the end I had to cut a link to get if off.

I then thought I'd test the theory that if aligned properly, with all the vertical links (ducks) in a row, from gypsy to roller, and a grooved roller, which I have, the anchor would come up the right way, so left the swivel out, and low and behold, every time since, (crosses fingers - hard to do when typing), which is quite a few up-anchors, the thing has come up the right way round..!

There's an additional complication when using a combination rope/chain rode: on retrieval, the chain re-loads itself onto the roller and gypsy however it wants to. Which in turn means the anchor will be returning "backwards" a big percentage of the time.

The swivel we have -- a relatively large, articulated/multi-directional Kong -- solves it by itself maybe about half the time. Looks like the Ultra swivel would solve it better, not inexpensively.

I also use the Kong swivel and haven't had any problems with it. I have it between the main all chain rode and a short length of chain (6 links) that attaches to the fortress shank with a shackle.

Even with the groove the chain occasionally gets a 90 deg twist in it, usually because it's coming in at an angle when retrieving the anchor. We have learned to be more patient, and to use the thruster to keep the chain coming in straight. Then no problems with it becoming twisted. So that 5% is when we are not being careful.

Yea that's one place I'd like a thruster .. at the stern.
While anchoring and backing down in a breeze.
