Re: The new Rocna was covered with a huge clump of mud/sand/grass

I just had to post this to be the number 100! Unreal!

While I am at it, I might just reply to gmac that if you are discussing anchor designs down there just as intensively as the UK crowd then I might just give the down under a miss. I don't think I can handle many more anchor discussions. Live really is too short and there are too many bays to drop your (name deleted) anchor in and enjoy a nice glass of red wine. Trouville knows it all.
 
Re: The new Rocna was covered with a huge clump of mud/sand/grass

gosh yes! 100 posts! i just posted how i found a skirt to be aboard! And saw that this post of webcraft (soon if nor careful to fall off the edge of the world,it being flat) has got to 100 posts!

Im anchored with a 25LBs Danforth 10m 8mm chain and 30m 10mm line.WX hot and fine!and a glass of pionot gris 2005 "medaille d argent paris 2006" Stellas makeing a salad and life is fine

We love our Danforth and the CQR is there to give us total confidence.
 
Re: The new Rocna was covered with a huge clump of mud/sand/grass

You're the lucky one. Behind this year, still in harbour. Weather good, tho'.

OT - Big issue. Anchor connector hang-up in slot. Photos to follow. Advice needed. Issue is how to stop hang-up or how to un-up-hang (i.e. make anchor hang down, and not up). All will become clear with photo, later today, or tomorrow!

Re: The new Rocna was covered with a huge clump of mud/sand/grass

I tried to get one of those but had difficulty - besides, I had already bought the new Kong before you first published that excellent idea. I wonder if someone can post the product manufacturer and part numbers for appropriate sizes for various chains and anchors?

Meanwhile, here is my hang-up /forums/images/graemlins/frown.gif This is a photo taken with it hanging from the bow roller - to clear it I would need to really put some force on it with the boat hook. Not a good idea on a moving deck and I don't know that the boat hook will like it for long.

I am thinking of putting a bolt through the slot to stop the connector from going so far down....any other ideas, or comments?

PS note that the chain is pretty old but the zinc spray has make it look much nicer at the end. So far that seems like an excellent idea if only for cosmetic reasons.
 
Re: The new Rocna was covered with a huge clump of mud/sand/grass

Is it jammed? If so, perhaps the Kong isnt big enough. I'll have to keep an eye on mine:

Re: The new Rocna was covered with a huge clump of mud/sand/grass

Yes, it is a rigging link, but it has to be the correct size for the anchor and the chain, and it has to have the correct axes of freedom. I think we eventually found one here in Spain from the Livemar catalogue but they were not available at the time.

It looks like a really excellent idea - far better than any of the connectors with the caveat that there is no swivel - but we really need some part numbers to order them from a chandlery. Without part numbers it is nothing more than an interesting idea.
 
Re: The new Rocna was covered with a huge clump of mud/sand/grass

Yes, it is jammed with the weight on. It will clear as soon as I relieve the weight but that is 25kg and a long way down. As soon as the jam clears the anchor will start to swing - not what I want, it will have to be sorted. I am going over to the chandlery to get a bolt - just a galvanised bolt, nut and washers, to reduce the slot.

[/ QUOTE ]Put a few links of chain between the swivel and the anchor. There is no need for it to be connected directly to the shank. This will also remove the sideways bending load that can currently be applied to that swivel.

[/ QUOTE ]How do I then connect those few links to the anchor? Just to recap, a shackle would be too wide for my bow roller and 'ears' and in any case, one reason for going for a connector instead of a shackle is to prevent the sharp edge of the slot from lying sharp-end-on to the shackle pin. The Kong connector has a much larger diameter pin than any shackle pin of this size and it cannot lie against the sharp end of the slot.

The lateral working load of the Kong (the model in my photo above, not all of them) is 2000 kg (i.e. 2 tonnes) which should be enough to cause the stock to bend before failing itself and as the stock bends, so the lateral force decreases by the cosine of the angle.
 
Re: Rocna

Having read a bit of this blog:

http://www.morganscloud.com/gear_failures_fixes/gfanchoring.htm

and given that I hope to save some money by anchoring a lot over the summer,

I've just had a flick through the Rocna web site and very impressive it looks. at 13m and around 13 tonnes, I guess I would need a 25kg at about £360.

My only concern was that, if it digs in like it suggests, (in the video, one guy had a hell of a job getting it out of the sand), isnt there a chance that it gets stuck in the sand/mud/grass etc. such that the windlass cant pull it out?
 
Re: The new Rocna was covered with a huge clump of mud/sand/grass

Richard, a lot of this stuff has been talked about here in the recent past...the "my anchor is better than your anchor" debate. I decided to buy a new anchor over the winter and we have bought a Delta partly because it had to fit on the existing bow roller.

If you take a wander along the marina you will see that the Delta and the Spade both have reservoirs for lead which is poured in to weigh down the tip. Indeed, the Spade is very Delta-like and both have a good reputation. I was able to buy a Delta from the local chandlery which was also important to me (Delta is marketed by Lewmar but, like most high tech these days Made in China!). Maybe that tells you something about the volumes that other yachtsmen are buying?

[/ QUOTE ] You can always get them out - use a bit of 'boat inertia'. Mind you, that's how I bent the CQR above.

Most important if you use inertia though, make sure the strain is taken by something stronger (and cheaper) than your anchor winch!

Seems to work fine!

Hi Lemain.. I usually 100% agree with most of your comments..

Except today where I 100% desagree.. /forums/images/graemlins/mad.gif

Although the Delta is a good all around anchor,

the only common point between the Delta and the Spade, is that both are ballasted anchors ..

The ballast of the Delta is cast seel.. (density 7,8) the ballast of te Spade is lead (density 11,8)

Weight distribution on the Delta tip: 28 %
Weight distribution on the Spade tip: 50 % ( nearly twice ..)

Angle of penetration of the Delta: like a " spreader "
Angle of penetration of the Spade: like a " Chisel "!( completely opposite )

Shape of the Delta: Plow
Shape of the Spade: Concave ( completely opposite )

I apologize.. but they are completely different anchors and in all tests where the Spade and the Delta have been compared, the Spade has <span style="color:red"> BY FAR </span> outperform the Delta /forums/images/graemlins/tongue.gif

Re: Re: The new Rocna was covered with a huge clump of mud/sand/grass

Alain, I will take your word for that...the reservoir <span style="color:blue">looks </span> as though it contains lead but I haven't tested it. Certainly the CQR is not ballasted.
 
I have a Kingston Quickset ( a sort of Delta with little side flukes) and it works very well.
It was bought to replace my Bruce which we were unable to recover after it had held The Goose solidy in 28 feet of water for three days of 10 - 15ft seas and winds gusting in excess of 40 knots of Cape San Blas (Florida). It was set on 25ft of chain and 150 ft of rode (fortunately there was plenty of swinging room) /forums/images/graemlins/ooo.gif

we also have another Bruce. a fortress which we use primarily as a lunch hook cos it's light, and a so called Danforth pattern kedge.
We have one anchor on all chain, the others on different combinations of chain and rode so we can ring the changes if, and as we feel conditions warrant.
We're very happy with our set up.

The only time I've experienced any difficulty getting an anchor to set was a CQR into hard sand on a calm day in Majorca.
Even diving on it was unable to force the point in. It just skipped along the bottom on it's side.

Solution - strung 10 feet of chain and danforth kedge from its crown and it set instantly! /forums/images/graemlins/smile.gif
 
We have now passed 100 replies on this post, let's see if we can break 200.

I have been very self assured on my postings above and stated (correctly) that I have only dragged once in five years with my trusted CQR. Maybe I was punished today for my cockiness. While sitting in the cockpit enjoying a good book I suddenly realised that the beautiful scenery of this little cove was passing by, not what you expect while anchored. Yes. my trusted CQR had broke out and I was dragging.

Having re-anchored, I tried to analyse the situation. This is a small cove with a steep gradient bottom. About 1 mtrs slope every 5 mtrs. Yesterday when coming in I was able to set the anchor "uphill" which is always very good and safe. However, today the wind changed 180 degrees and I was hanging away from the slope. My scope was only 4:1 due to the small cove and rocks all around, I needed to contain my swing. That scope proved to insufficient. The anchor broke out from the slope. Would another anchor design have held? I guess you will never know. I re-anchored on basically the same spot, but now with the anchor laid the other way and with 5:1 scope. That is now holding fine. I just have to be awake to watch the swing and make sure we don't hit the rocks on the side in this bay.

The point I think this underscores is that there are so many more variables to anchrorage than just anchor design. I still trust my CQR to the end of the world, but you have to understand how you deploy it. Just as any other anchor. A "new design" might be great, but only if you also know how to work with all the other variables you have deal with in setting an anchor. Don't expect one design to be the solution of all anchoring problems.
