Re: Rocna vs. CQR dimensions

Well eventually I took the plunge and dumped the CQR in place of the Rocna40 and hoped it would fit the bow roller of my Jeanneau 54DS (2008). Now absolutely delighted, it fits perfect and indeed the safety pin passes through the bow roller and the Rocna. Previously with the CQR the safety pin only sat above the CQR shank. Have only had 3 opportunities this season to use the Rocna and I feel much more secure. I am bringing up much more mud/weed with the Rocna than I ever did with the CQR so its clearly digging in much better.
Only downside with the Rocna40 as opposed to the CQR is that I wanted to fit a removable Selden Bowsprit using my port bow roller but because of the hoop this limits the amount of room available so it looks like I will have to have something custom made that sits on the outside of the port bow roller, other than that very happy with my decision.

Thanks for the input. I still haven't pulled the trigger here. As mentioned above, I did swap out the chain this season. That was a great idea. It expanded our anchoring options tremendously.

Where are you located? What year 54? What engine? Would love to swap some notes with another...... PM if you like.

Re: Rocna vs. CQR dimensions

I have a friend who mounted his Selden pole to extend THROUGH the Rocna's hoop. Worked great.

Re: Rocna vs. CQR dimensions

Can't remember where I saw it but they mounted the bowsprit on the hull just below the toe rail. Was a brilliant solution to the problem.

That last part may be unwarranted, I'm more focused on how they will hold up in the long run.
Interestingly enough, an acquaintance of ours and a staunch proponent of the Mantus anchors, came to anchor near us off St. George's a few months back. I believe we saw them anchor ten times before they were happy. Not a criticism, just an interesting observation.
With our Rocna, we've never had to do it more than once in that anchorage or any other.

Funny thing, these are cruising boats who have come a long long way from the ol caribe, and most of the rest of the world, I'll tell you the predominant type of anchor is still the CQR on this little outpost. I'll post a little video when I get a better wifi signal..of what boats that have probably been out here a bit longer. They must not have been close enough to a lot of hype. Sure, go ahead get one, i would too if they weren't double the price...but i have no doubt it works for me and quite a few others.
I bought my first GENUINE CQR in 1971 and used them consistently all over the world until 2012. It was a great anchor, all around out performing every other anchor I tried.
Reading on the forums and elsewhere on the web, my response to "new gen" anchors was pretty much dismissal. New gen, shmoo gen. My CQR was fine.
Then in 2011 I saw a boat anchor successfully in Admiralty Bay in the 'drag chutes' on the south side. Ever wonder why there are no boats anchored in some areas, when the rest of the anchorage is chock a block? Anyway, I hopped in the dink and asked him what anchor he used; Rocna.
I began to pay attention and everywhere we went the Rocna was doing the job better and with less reanchoring than any other anchor.
In 2012 we were offered a nearly new Rocna at a small percentage of retail, so I figured for a couple of hundred bucks it was a good experiment, and if it wasn't any good it would make a good paperweight.
We dove on that anchor nearly every time we dropped it the first year and it set itself (I NEVER back down on my anchor unless anchoring Med style) within ONE anchor length nearly every time, occasionally actually moving a whole ten feet before setting!
In three plus years of being anchored all but maybe 25 nights, this anchor has NEVER drug, had to be reset or given me any sleepless nights (winds to 65 mph) on any bottom we dropped on, in the Windwards or Leewards.
Sure there are still a lot of CQR's out there, and the Rocna's are expensive, but everywhere we sail there are lots of CQR's for sale at ridiculously low prices. If only I wanted one.

Re: Rocna vs. CQR dimensions

Capta, why do you never back down on your anchor?

I always do and this summer what felt like a firm set was actually kelp, discovered by backing down hard.

Perhaps I misspoke. I will back down very gently if there's not enough wind to lay out my chain.
I found out long ago that I often unset an anchor on it's way to a good set, by backing down on it. The good anchors are designed by guys much smarter than I to do their job properly, without too much help from me.
To be fair, there isn't much kelp down my way and when last I anchored on the left coast, there were no CQR or Rocna type anchors. However I would suspect that even if my Rocna did pull through the kelp, it would pretty much set the second it could do so. If you turn up the heat, stop the rain and warm the water, We'll sail on up and you can show me your beautiful world.

Re: Rocna vs. CQR dimensions

I would encourage people to "power set" their anchors.

In light wind if you just drop your anchor without any reverse force it will look like this Bruce, although with care you can lay the chain better than this skipper:




In most cases of steadily rising wind the anchor will set very nicely on its own. This is particuarly true of modern anchors like the Rocna that set very reliably. However, leaving the anchor to its own devices has some problems.

The first is if the substrate is not ideal. This take the form of isolated debris.

This Delta has been dropped with very little force. It is still totally unset on its side. With some rising wind it will move backwards, rotate upright and dig in, but what about the tyre? Will the anchor fluke catch on this preventing it setting? A "power set" would have revealed the problem.




Sometimes the anchorage is unsuitable because of natural problems. Many anchors struggled at this anchorage. This is a Kobra that was slowly dragging in only light wind:




The other problem is if the force on the unset anchor increases very rapidly. Say with little or no wind and then a thunderstorm.

Ideally anchors like to set with gradually increasing force. While they will often set satisfactorily with a sudden high load but this is much more difficult for an anchor.
