And from that we can potentially draw lots of different conclusions.
Oyster have got a cheap deal with the CQR distributor.
Oyster know nothing about anchors.
Oyster owners don't get involved with anchor selection.
Oyster owners dont anchor very much.
Oyster have conducted extensive research into anchors and concluded that the CQR is the best one to securely hold a very expensive boat.
Almost all Oyster owners have conducted their own research and have chosen a CQR.
Being a skeptical sort I am more inclined to believe the first two than the last two.
You forgot one possibility: Those who buy traditionally-styled boats prefer traditional anchors that were around when they were lads, not these new-fangled gadgets.

Well I should probably shut up until I've read it, but were all the other recent tests not done by well respected authorities, etc, etc?
From what I can see from the above posts, Rocna/Manson/Spade better than Delta better than CQR/Bruce...so what's new? That's been the results of all these tests all over the globe for years.

Not in my opinion. Some examples:
1. Funny how a French plough anchor outperformed everything in tests carried out by a French magazine.
2. The Hydrobubble came top or near the top in one test, never came near it again.
3. Fortress came out best at resetting on one test, whereas the experience of many yachtsmen is that it is rather poor at this aspect of anchoring.
These, and many others, suggest that for whatever reason those tests are not repeatable.

I assumed that he used the Danforth to restrain his test rig. This therefore proves that the Danforth is the best anchor if you don't want it (test rig or boat) to move.
My boat has a Danforth.

Meanwhile, those of us with a Spade just sit here feeling unbearably smug!

Lightly used? is there not a danger of it getting wet out there if it ever rains?

And don't whatever you do actually dip it into the sea, or 
into the seabed!! The nasty sand, pebbles and rocks might scratch it...or (even more ) entrap it and you'll never get it back!
Actually, I've got a conspiracy theory about all this anchor testing. My hypothesis is that PBO sales are falling and they know that anchor tests are so controversial that everybody wants to have their say. So...they need to go and buy the mag (even though they wouldn't otherwise) to ensure they are 'fully informed' when smugly looking at the rusting CQR copy in the next berth and commenting to the owner that "PBO didn't rate that very highly you know"
Or (theory number 2) that this is all part of the Rocna comeback strategy with huge sums of money being left in used notes in a brown suitcase outside of PBO's offices. Snooks will undoubtedly confirm this to us, being an honest fellow.
Anway, I'd better go and buy PBO and have a read of all this nonsense I suppose.

I use a CQR but for various reasons need to replace it. I decided on a ROCNA (I need a 33 for my boat) called the distributors - sorry sold out you can have one in August. So i had to buy something else!
Nothing wrong with a CQR but technology moves on and these new Anchors are better than than odder design. Like the CQR is better than a fisherman (in most situations) but they all work.

One finds one only takes photographs of one's anchors when they are fresh out of the purveyor's bubble wrap.

Which of course you've kept to wrap it up in at the end of every day (after it's been polished)

The only reason I have any misgivings about the Spade is that when Parcel Farce delivered it, the packaging was marked 'Fragile'. Had it been a Rocna, I'd have understood.

When I ordered a Manson Supreme a few years back it came with NO packaging whatsoever! The bare anchor appeared on my doorstep courtesy of Parcelforce with a sticky address label on it! Mind you the prices seem to have gone up a bit since then, so maybe their dealers can now afford bubble-wrap as well

Oyster will supply a CQR but should you want another type they will supply it instead.
They are evaluating different anchors and taking feedback from owners on the anchors they have and how they perform.
I know fom Oyster that evaluation of all parts used and intended for use on Oysters are continually evaluated and changed if need be. You do get feedback from Oyster on a regular basis on any problems they find with any item on the boat and value customer feedback

Looks like a Fortress to me. The text says he used three of them, although I can only see one in the photo.

This article on the test by Professor John Knox, himself an experienced sailor is seemingly unbiased, attempts with a few common anchor types, to show their performance in just two sea beds. One of course wet sand the other of wet sandy mud.
He makes the point that to have even more conclusive tests the man hours would have been impracticle for him and his assitant. He also points out that in very different sea beds, results would have been different. The ability to initially penetrate the sea bed and then the ability of anchors to stay held fast to the sea bed rather than dragging or breaking out, being the most significant variables between anchors.
Using the 6kg Spade as the 'bench mark' after 9 tests, about which others are defined, gained a score of 120kgf.
He concludes that the Ultimate Holding Force UHC = the maximum Capacity the anchor will hold without moving in the seabed, of the anchors he tested was as follows.
Best first.
Rocna 15kg = 480kgf
Spade 15kg = 420kgf
Manson Supreme 25kg = 225kgf
Delta 35lb = 186kgf
CQR 45lb = 175kgf
Spade 6kg = 120kgf
Rocna 5kg = 85kgf
Bruce 15kg = 80kgf
Delta 15lb = 76kgf
CQR 15lb(dug in by hand) = 68kgf
Bruce(Marathon)15kg = 50kgf
CQR15lb = 44lb
Bruce(Atlantic) = 43kgf
Bruce 5kg = 35kgf
Delta 9lb = 34kgf
Why he failed to test the Fortress and Danforth I question! ??
The efficiency= UHC/Weight, put the Spade just first, Rocna a close second, with the Manson third. The rest were very much behind the leaders Delta,CQR and Bruce in that order.
An interesting test I've done on the boat to demonstrate the depth and holding power of concave and convex shaped anchors..............
Take 2 similar size/shape desert spoons.
Bend the spoon of one back on its normal position by about 70 degrees, the other forward of its normal position by a similar amount.
You have two miniature anchors. When dragging the two into a bowl of sand or sugar see which one digs in deep and seems to hold best and which one tends to drag and break out.

As I can't afford to waste two spoons can u let us know the result?

PM me and I'll post a couple from my local Oxfam shop!
It's also been interesting that Spade mentioned a few months ago that their new anchor, a near direct copy of the Rocna and Manson Supreme is currently advertised a couple of pages on in the same mag'. Interestingly they are not making a 15kg version and presumably using different quality metals!

Ah - but what kind of sugar? What works in white granulated sugar may not work in Demerara. And is the sugar covered by coffee, cocoa or tea? And which model Landrover did you use in the tests?
