I wait for my Bruce to let me down, so I can then use my FX55 that remains neatly stowed in its lovely red bag. Heck I'd like my Bruce to get stolen so I could install a SARCA or Rocna or Manson so I could join the current decade. But alas, to no avail. the Bruce keeps on soldiering.

I think the tests on hand have revealed enough to kind of sort out the basic differences of most anchors. I've got a sack full of favorites and a few I wouldn't bother with. But there's only one that I drag out when it's really going to blow. My favorite of course. And of course one could say that's not totally objective and be correct. But I may have come to have that favorite through objective observations and experience. Marin's experience leading him to the Rocna as he relates it sounds very logical and even objective. And now he's probably upset that the Rocna isn't perfect ..... all our favorites are perfect of course .. until they are not. In this case Marin predicts that ahead of the dawn of reckoning. Interesting that we're all being so objective and choosing different anchors. Yup anchoring and anchors must be Voodoo.

I've seen quite a few tests typical of this one. What do you choose to believe? This test shows the Claw and CQR doing so poorly one would question if using one of these anchors is actually safe. Then you read about very experienced trawler skippers on this forum cruising SE Alaska for many years regularly using these anchors.

What input should you rely on?

By the way if you're presenting this test in support of your favorite anchor it would help your cause if you'd provide at least a hint of what this test is and who conducted it.

Windmill, that chart doesn't reflect my experience. The anchors I deployed always worked.

I never owned a Ronka but did own a Manson-many Danforths-Fortress-delta-genuine CQR-genuine Bruce-aluminum spades(2)-and an ultra. I can remember only a few anchor failures in my 50+ years of gunk holing. In Annapolis harbor on short scope in a thunder storm. my Bruce with all chain holding a 40 ft Pilgrim(fair amount of wind age) had moderate but not dangerous dragging. The application of a little motor thrust until the peak winds subsided handled that situation. I experienced two full blown anchor failures with Danforth and Fortress where 180 degree clocked wind in T storms broke anchors loose with no reset plenty of room and good anchor watch so no real problem. Both times anchors in relatively soft mud and Barnegat B and Chesapeake). My CQR on short scope all chain I suspected minor drag on occasion. With all those anchoring's not a perfect score but pretty dam good for 50+ years. I know its not just the anchor its the effort I put into picking my spot and my judgment on the set which I repeat or back up with the #2 anchor if in doubt. Yes as said by others I think too much emphasis on the anchor type its only part of the equation.

I've never said our anchor is perfect. I said-- and still say-- it's the best all-round anchor on the planet. And based on all the user testimonials I've read over the last eight or nine years, I have a whole lot of company around the world.

Claiming it's perfect would be stupid. No anchor other than a Cat D-10 buried in the mud can be perfect. The fact our anchor isn't perfect is why we carry a totally different type of anchor on board, a Fortress in our case.

But based on the user testimonials we've berm reading for years, and on direct testimonials we've heard from people in our marina who've used the same anchor in extreme conditions in open anchorages in the southwestern Pacific, we remain convinced that when we bought the first of our anchor brand sold in the PNW we bought the best all-round anchor available today.

In our opinion, all other anchor designs are inferior for recreational cruiser use in the sizes most of this type of boat uses. And in the eight or nine years we've had our anchor, we have seen no reason whatsoever to change our minds.

Perfect? Of course not. Better than all the other so-called all-round anchor designs? Absolutely. It's why we kep ours locked to the boat: we can't replace it.

This personal reaction runs deep in all scientific endeavor. If results don't seem right retest take a new tack accept when and if the proof is overwhelming. Apparently I am not yet overwhelmed by the fortress findings regarding the spade types.

Ah. Got it.

Yes, testing methodology/technique/execution can be difficult to design, fund, control, and evaluate.

I tend to see the "glass is at least half full" results, so I've been looking at the results as a positive for Fortress (in this case) and not as a negative for other brands.

Greetings,
Mr. 42. "...glass is at least half full...". Maybe someone started with too big a glass.

Speaking of glasses, maybe anchors are like wine glasses, one for every type bottom or situation....

Yes Marin I probably over expressed myself on my post. The Rocna isn't perfect as time has shown and I won't claim any of my seven or so anchors to be perfect either. But all of mine and all of yours are perfect in our minds as none have ever failed. My first XYZ failed with big time setting problems and it's now in a small land fill in Alaska. But if we have no anchor failures when we hang up our prop for the last time we can then say they are perfect. But for now if several anchor tests find an anchor that performs below the pack that hook is at least suspect at best and probably worse.

But it's hard to believe anchor tests that show the most common anchors having extremely low performance. The only way I can explain that is to point out that anchor tests subject the anchors to extremes .. such as 5000lbs of tension on the rode. Most of us probably go for years w/o even coming close to those extremes. We went on a 2000 mile trip w our Albin 25 using a smallish Claw and probably saw no more than a 15mph breeze as the weather was very nice and of course had no problems w the anchor. I've never been in a gale w anything but an XYZ and reach for that anchor when over 40mph winds are predicted or I think may happen. And how much tension was on my rodes in the three gales I've been anchoring out in? Perhaps I'd have been fine w any of my other anchors. I've talked to fishermen that do fine w a Dreadnought anchor. One commented "It does fine in 50knot summer gales but drags in the 60 knot winter storms". I have a Dreadnought sized for my boat and consider it the lowest holding power anchor I have and would not put it out in a gale but until I've done it I won't know. Most any anchor seems to work fine for most of us and the reason may not be that they all have good or high performance but that we don't make high demands on them. That's the beauty of the anchor test in that they DO put high demands on the anchors.

I've read stuff about air drag over the years and suspect that most or all the predictions are not true. But it would seem to me that if one was to predict error it would be less drag rather than more. I've never had to increase rpm in 40 knot winds.

So I suspect the unknown factor in anchoring may be the low level of performance we actually need to keep our boats off the beach. I wonder if I tethered my Willard on a line in a 40mph breeze how hard it would be to hold it? After doing that I may come to the conclusion that the 13lb Danforth that came w my boat was plenty big enough.

I've noticed for years that bigger vessels have comparatively small anchors. And lots of them (perhaps most) are not high performance anchors. Perhaps that's the reason anchoring usually goes quite well .... we don't need much of an anchor. If we started using smaller instead of bigger anchors we may be very pleasantly surprised how well it goes. Perhaps a 10 or 12lb Supreme would do fine on Willy.

Unfortunately, this chart included a false pull with a >5,000 lb tension spike which inflated the numbers of the Rocna 35, as noted in the test report below, and this information was not used or reported by the other magazines who attended the testing.

The other two charts from the Sail magazine story are below as well.

My recently purchased 28' Cape dory came with a 7.5 kg Stainless Trefoil (Bruce clone) on the rollers...
Seems a might small to me for serious and regular anchoring out. For years (on the Chesapeake), I used a 22lb Bruce on my (15,000lb) Bristol 35/5 and never had an issue...
I rooted around in the attic for old boating gear and came up with an FX11 and FX16 fortress. I'll be adding both these to the on board inventory and suspect I'll be covered well!!

I knew the regular Spades had a short scope problem but this is the first time in a test that I've seen that the Rocna did well at short scope. Not in chacter but a welcome sight to see.

But here the same trend seems to prevail. The newer anchors do well, as generally expected (probably) and the older anchors that huge numbers of very experienced skippers do use currently do terrible. Not just poor but terrible. Most every test looks like the results have been cooked to make make an advertiser happy. So much so that I wonder and wonder. How can these newer anchors do so spectacularly and the old standbys do so so poorly.

And here the short scope performance indicated by the Wasi is really super. Wonder how they arrived at that. Makes me think of one of the new Spades that looks very much like a Wasi.

Could anyone post a link to this entire Sail Magazine test?

Eric-- I think your post 131 is very well thought out and is probably spot on.

Every time we go out we pass the Vendovi Anchorage which is one of the places tankers hang out waiting to load or unload at the Anacortes refineries. Their anchors weigh tons, but in comparison to the size of the ships they seem ridiculously tiny. Yet they hold those tankers in the same windstorms that come blasting through Bellngham Bay with 50-80 mph gusts.

So far our rollbar anchor has performed flawlessly in every bottom in which we've used it. We hope and expect this performance will continue. But... if it should let us down in a big way under conditions we think it should have done well, which is what our Bruce did one too many times, it will get the same treatment as the Bruce. We will go in search of something more reliable and our current anchor will go off to the landfill.

There is another write up of the same data in Yachting Monthly here:

http://www.manson-marine.co.nz/Ancho...hly%202006.pdf

When looking at anchor tests you really need to read a large number to gain some perspective. This link from Manson lists some of the independent tests and is a good starting point :

Most anchor tests, in those Manson links etc, are conducted in sand - and largely come to the same conclusions - that the newer anchors are better - in sand.

Few anchor tests are conducted in mud (except Practical Sailor) and very few in thin mud. I do not think there are any in weed.

The Fortress tests cannot be extrapolated to a medium to hard sand seabed, but might have relevance in very soft sand. The Fortress tests cannot be extrapolated to weed.

But the Fortress tests are indicative of performance in thin mud - and it is difficult to refute the results - as no-one else has bothered (possibly because their anchors have never been tested in thin mud).


I note that despite the volume of criticism of Fortress tests - no-one can come up with a better protocol. It is shame we can be so negative.

I'm not sure why they ran the test...they could have polled a bunch of experience cruisers who probably would have said the Fortress would do well...I was one that predicted it as well as others here....

While I doubt it was true that Fortress started with the premise...yet the test was almost guaranteed to make others look really bad...even if the fortress didn't look too good either. Anchoring in soft mud isn't high on my list of things to do..but nice that fortress proved it's merit IN THIS CASE.

Good in mud doesn't mean anything more than that...doesn't mean good on my pulpit 24X7...unless I only boat over thin mud.

Throw in the debate of reversing and yawing and yanking..sure there are variables...but not many I know would have bet against the fortress in that test..whether it is relevant or not.

There's a lot of going back and forth here and I don't see people understanding other's positions....by reading a bit between the lines.

Apparently you didn't read post #12. As others have stated, most of us can likely get whatever anchor we have on our boat to set in most any bottom. The more important question is what will happen when wind and / or current reverses. IMO, without this part, the test isn't terribly useful if you like to get a good nights sleep on the hook.
