Hi John,
I am glad you have had such good luck with your Rocna. It, like many of the new gen anchors, are amazing at initial setting when they are clean.
The following should be read as written from someone who believes a ground tackle system, in its proper design and execution, sometimes (perhaps often) has you and your crew’s life residing in its effectiveness. There are those that say that they rarely spend the night at anchor, usually use it as a lunch hook or for fishing: to them, I would say that it is also there for emergencies, unexpected squalls and engine breakdowns, where a good system proves itself invaluable. Those of us who cruise know how important it is at least a few times each season.
I would want you (or anyone with a swivel) to consider ditching the swivel for the following reasons:
The ground tackle system is to keep your boat and crew safe and nothing in that system should compromise that goal. I believe swivels do so compromise:
1.   Attached as advertised (looking at the Ultra’s web site the installation is straight onto the anchor) introduces the possibility of the anchor getting jammed and side loads prying the jaws apart. (Google anchor swivel failures for examples.) Adding a bit of connecting chain, as Daria suggests, mitigates that issue while introducing even more shackle connections (every connection is a potential vulnerability) and the likelihood that the one favored reason for buying a swivel (clean retrieval onto a roller) would no longer work so effectively.
2.   The Ultra (and most highly advertised and hyped swivels) is made of stainless steel and ss (in my judgment) has no place in a ground tackle system that, by definition, is in and out of salt water. It is potentially too brittle and prone to crevice corrosion and there are alternatives, all better, to ss shackles, anchors, chain etc. that one sees wherever there are boats.
3.   With the possible exception of anchoring for long periods where the boat circles its anchor repeatedly CW or CCW (and I have lived this scenario a couple of times without a swivel), a swivel does not contribute to the effectiveness of one’s ground tackle. Chain twist is always relieved by an adequate snubber.
4.   The advertised strength exceeding chain does not specify whether proof coil or high tensile. Among cruisers, HT is becoming more common. I would be in its strength if the anchor end was held rigid and the pull at right angles.
5.   An anchor that comes up backward is annoying and can entail a bit of fussing, but introducing a vulnerability into one’s ground tackle system in order not to be occasionally annoyed is (again my opinion) in no way justified.

Interesting video. I have now been using my Rocna and Ultra swivel for three years. My anchoring has been restricted to the UK which is sand and mud. This combination is the most effective I have ever come across and have never failed to set 1st time. Always reversing slowly. The ultra swivel always presenting the anchor as required to the roller.

Hi all,
Please go to the swivel area of this list serve where for a fuller discussion, but for here, I will say that I know of no significant problem that a swivel solves and have been anchoring for 30+ years without one. The thought of introducing such a problematic element to a ground tackle system designed to keep you and your boat safe just to help with the occasional backward anchor seems quite misguided. I do know they have proved a weak link to a number of vessels and that I am not alone in believing that stainless steel, the material most are made of, has no place in a ground tackle system.

Hi John, Good to hear from you. I have never had an anchor that always came up facing the correct way to get it onto the roller easily. They all needed occasional tweaking. Were you correct in reporting that it “always” comes up backward? That would surprise me and be curious.
My best to you and to the SYH crew,

Hi Tim,
I am glad you have had such a good experience with your Rocna and I am not surprised you find a huge improvement over your CQR, as you clearly give homage to. BTW, I do not believe your anchor to be overweight, perhaps it is even underweight depending on your tonnage. My Spade anchor is 35kg for a 40 foot/16 ton boat which I think is about right for those who occasionally anchor in marginal conditions where gale level winds might visit un-announced.

Hi all,
There are some comments pertinent to Rocna 's and new generation anchors as well in the Anchors and Anchoring section. See particularly Simon 's report.

Thanks for the advice. Much appreciated, but like you I am not a fan of swivels and I 've been using the occasional but very quick 90 degree twist for many years, happily without being bitten yet!

Re the warning about Rocnas losing grip and dragging on wind shifts, all I can say is that after years of suffering from having to re-lay 1:4 times and many dragging incidents with my CQR, I have deployed my Rocna 100s of times over 7 years in every type of floor and conditions including many wild anchorages in the Beagle Channel where you get 50+knot williwaws screaming in at 90 degrees from previous wind angle. I have to re-lay only about 1 in 50 times now and , touch wood - crossed fingers, my Rocna has NEVER dragged. Granted it is a tad overweight at 40 kg for a 48 ft boat, but my Rocna has been a life-changer for us.

Instead of turning your chain in the gypsy(capstan), you might consider unshackling and turning the shackle. That way you do not bring a twist down below-decks that can bite you at some point in the future.
Though we are not proponents of swivels, we have been testing and using the Ultra flip swivel now for over a year. it forces the anchor to twist into the correct orientation as it passes over the bow roller.
I can give you a link to a discussion on swivels if interested.

Occasionally my Rocna comes up back to front. If it happens twice in succession I turn the chain in the gipsy through 180 degrees and end of problem for a while.
