Rocna Vulcan 15kg vs Spade S80?

[geem]

The OP is asking about the 2 different anchors, but I did need to include old but good test results that include the S80 and Rocna Vulcan. The latter has lost in my opinion, but drifting off topic slightly, why do you show an interest in any anchor that can break or bend ??

Also the 180 degree veer test should not be ignored, unless you always set 2 anchors to cover the fact the modern spades are a real disaster in a 180 shift:

Pity that test did not include the Rocna Vulcan, but at least in includes the S80 spade.

I was once told by a very good trick cyclist in the USN when I was contracting for them as a test pilot, that when an adult who is either not very intelligent or who has been brain washed will never, ever change their minds once they have formed an opinion about an important subject, (We were talking about a lecture I was doing about Afghanistan and the US mining industry). A few weeks later after I had finished testing a new aircraft, he called me back and I had to admit he was correct, as the best I ever got from a member of the audience who attended my lectures and was presented with all the facts to prove they were wrong and the Brits were right about the causes of that war, was one USAF pilot saying, "OK, but it's my side, right or wrong". It's very like that with anchors, you can present all the right data about performance and failures, but no one in any forum will change their minds and admit their main anchor is no good in a storm, or if compared with another type.
I don't know who wrote the Morgan test article, BUT they are very intelligent indeed, as when presented with the 180 veer test results actually published what is in effect an appolgy to the old timers like myself, who really did know how good the CQR and Bruce anchors are.

No they didn't

You seem extremely confused.

First there is no such thing as a "modern spade" anchor. Spade is a brand and is a different design from other anchors.

There is no test that you have included that compares the Spade with the Vulcan - partly because the Vulcan did not exist in 2009.

You are totally wrong about the performance of anchors when the wind shifts - the YM test clearly shows that the CQR is extremely poor in this respect , but the new generation anchors are far superior. This is one of the design objectives of the new style anchors - initial setting, higher holding power for a given size and re-setting after a wind or tide shift are the properties where nearly all new generation anchors including the Delta which is the simple successor to the CQR are superior.

As to bending shanks, Jonathan has already explained the background to that issue and that is a red herring.

BTW I am an oldtimer myself but perfectly able to examine the science and the empirical evidence that shows pretty conclusively that the old style anchors from the past are inferior in every respect to modern designs. Indeed it would be really depressing if it were not so, given the amount of intellectual energy, money and hard graft that has been expended in developing them.

Some might think that @TNLI is just singing the praises of CQR's because he has one to sell Seriousy good used genuine 35lb CQR in Poole.

But then, I have an old one for sale in there too so keep going TNLI...

Posted on another thread but more relevant here

Spade has been certificated by Bureau Veritas as a VHHP anchor same as SHHP from Lloyds. I'd buy the Spade, its the design on which Rocna is based but the less focussed ballast demands the back up of the roll bar. Vulcan - I've never tried one.

Now the question is, is your storm anchor in one of these pictures ??

You have no idea how any of that damage was caused.

I suggest you check the name and manufacturer of the anchors. You are maligning a manufacturer - and its not their anchor.

It was caused by a light breeze down under in good holding!

I will visit Specsavers online to see if they can read the labels, but off hand it looks like some kind of copy of a Bruce, as a Lewmar Bruce has been bent, so very unlikely it's one of their good anchors. The slightly bent corroded Manson has a very distintive copy designed to trip the anchor when veered through 180 degrees, (See the slider cut out in the shank), one stupid design concept. The Rocna is one of the few anchors with a roll bar, the yellow paint clearly identifies that one as a UK Spade Ltd S80, (A good anchor), The Excel is obvious and the genuine CQR looks unbent. All of those anchors were from yachts in an Australian marina.

And your point is?
I saw an anchor get bent on the bow of a yacht in a marina in Portugal. Another boat ran in to it side on and bent the anchor. Lots of damage to both boats and a very bent anchor. Nothing to do with quality of the anchor and not something you would experience in normal use. You are showing photographs of what may be similar incidents.
How an anchor survives in such a collision is not relevant to normal use.

I just noticed that one of your 'broken anchors' is actually a disassembled MANTUS. You have is labelled as a broken Excel.
Are going to persist in posting incorrect and totally misleading information? You lose even more credibility than the very little you already have. You seem to be on a mission to slag off every reputable anchor manufacturer on the planet. As far as you are concerned the only decent anchor ever made is a CQR. That myth was busted many years ago. Anybody who has done a reasonable amount of research on anchors and owns a new generation anchors know that you are spouting utter nonesense.
My only reason for responding to these ludicrous posts to ensure that any newbies researching anchors doesn't stumble on your posts and start to be taken in by your grossly inaccurate and misleading posts

He's trolling.

It’s a very odd thing to do, why would one? What’s the point? There are few enough hours on the planet as it is without wasting some…….

I think Spade are exclusively made in Tunisia. I find the idea something of a joke that a French designed anchor, managed by a French business would have any made in the UK. It was a significant slap in the face for Lewmar and a major coup that Spade had the Shannon boats equipped with Spades. I have nothing against Lewmar - but they took their eye off the ball - and those Spade anchors are prominent on the foredeck an d will be there for years.

He states few or no modern anchors are Classification Society approved - most are approved (or have been approved)

He offers 6 photos of bent anchors without bothering to find out how and why they were bent.

Last I heard genuine Bruce anchors have not been made for years by Bruce - if you buy a new one - its a copy

Lewmar transferred production of CQRs (and Deltas, designed by Simpson Lawrence and their Bruce copy) to China. The Chinese CQR copy only have a passing resemblance to the original. Their Epsilon (Lloyds approved as SHHP) also made in China

He spruiks Danforth - I wonder if he actually has a genuine model.

One of the reasons we have a Spade anchor is that it was recommended to me by my old CO years ago when we met up at an anchorage off Houat in S Brittany. I remember him explains that they’d got a new anchor and ‘it sticks like glue’. Why am I telling you this? Paul went on to become chief executive of the RNLI. I’ve no idea if his personal experience of Spade anchors on his own yacht and the RNLI’s subsequent adoption of Spade anchors is a coincidence or not, but I thought you might be interested in the trivial anecdote highlighting a coincidence. I’m assuming the RNLI did their own testing before buying.

It’s one of the great mysteries of the internet. Almost all forums have a pet troll or 2.

For the sake of completeness. Two genuine CQRs. Given sufficient force any metal object will bend or break, depending on material properties.
