I have hesitated to post this but have decided to be brave and go ahead; the issue this time is slightly different as handleability when deploying and recovering is the big issue for me.
My last boat was A Sigma 38 with an open pulpit and powered windlass which carried a CQR and Bruce anchor. We have downsized to a Finngulf 33, typically Scandanavian, with fine bow profile and double rail pupit. I have a thing about keeping weight away from the front end of any boat. When I went to buy a 15kg. main anchor for the Finngulf the only one in stock locally was a 10 kg. Delta which so far has performed well for the last two seasons ( though it has not been tested above F5-6) with 45m. of 8mm. chain plus a reel of 14mm. nylon rope. Our reserve anchor is a 22kg. genuine Bruce which I have had for many years, (originally a mooring anchor for a Trapper 300 it was then only put down once a season with 1/2" chain so it got well dug in.), it has about 15m. chain then rope.
I keep the Delta anchor and chain behind a home made removable bulkhead beam in the aft part of the bow anchor locker unless I intend anchoring again within 24 hrs. when it can stay on the bow roller. (The boat has a through deck Furlex). The chain is contained by old polythene washing up basin with a hole in the bottom to let it drain. Despite the smaller gap in the double rail pulpit I have no problem deploying and recovering the Delta by hand, however the bigger heavier Bruce would be quite a big problem so I need to replace it.
My intention is to get a 15kg main anchor to replace the 10kg. Delta, remove the Bruce and keep the 10kg. in the cockpit on board as a reserve/kedge. The issue is handling as I want to continue to keep it in the locker most of the time. I like the Delta it digs in well and is easy to stow but I am inclined to think that two anchors should be of different type and the 10 kg is only adequate, but this might be a mistake?
No one around here stocks a choice of anchors so I am dependent on 'scuttlebut' for info.
I fancy a Spade which seems to be the daddy of modern anchors but I think the UK price is ridiculous for something you can not see before you buy. I had seriously considered the Rocna or Manson but the big tubular roll bar looks awkward for getting the anchor under the pulpit and stowing though I suppose it can be used as a handle, however Rocna's response to a recent poster with a galvanizing problem seemed decidedly lukewarm ( they offered to re-galvanize rather than replace) and again you cannot examine or handle the product until you buy it (though I understand you could make a paper replica of the Rocna, the weight and balance would be hard to replicate). A 15 kg Bruce type from Lewmar/ Bainbridge is more widely available to see and handle and they are quite cheap, also there is apparently a rare cheaper version of the Spade called a Sword or Oceane though I have never seen one. The Manson is stocked in Inverness which I can reach by boat but Gael Force is a long way from the marina so I could not try it on the bow.
I used to have a Sigma 33 OOD which would have had similar weight and windage to the Finngulf, the prescribed one design anchors were a S.L. CQR with a smaller Bruce kedge though I have forgotten the weights which were probably in pounds, oddly, the smaller Bruce seemed to perform better in kelp. Danforth/ Fortress shape anchors while well regarded seem to be for the E. coast
If I already had a 15kg Delta I think I would have been happy with a 10 kg bruce reserve. On the W.Coast of Scotland where I am, most of the recognized anchorages are mud or sand, the biggest problem is the kelp in places like Canna; I tend not to anchor over rock if possible.
Would anyone like to comment again on a suitable anchor taking account of performance and handleability or should I start saving close to £500 for a Spade. I know that you have all been over this before, I have read the YM and PBO tests and all the old anchor threads which all seem to end with a guy called Smith, but my big problem is that I can only see and handle a Delta or Bruce. I have walked around marina pontoons and looked at Spade, Manson and Rocna anchors, visually the quality of the engineering and galvanizing seems to be in the above order but again I have not handled them, based on visual design rather than performance the Delta or the Spade look better (prettier) than the roll bar anchors.
I am not intending to install a powered windlass in the forseeable future; any insight based on experience would be gratefully received, apologies again if you think this has been raised too often but when you are intended to spend hundreds of Pounds on something you cannot see, you need some sort of help?

Well I dont think that you can beat a plough style in the UK.... so maybe you should consider keeping the Bruce as the kedge.... and simply upgrading the Delta to 15kg...

IME These modern jobs like the Rocna tend to have high holding power once set but are more difficult to get set than a plough style... Plus they are jolly expensive.


If your happy with with the Delta but just want a heavier one.... why not just do that???

I always wonder about the arguement of having a different second anchor as a kedge....

If the first one has set ok and you want to add a second.... were is the advantage???

How many times have you had a problem getting the first one to set... and then chosen to dig out the kedge in the hope that it will be superior... when in fact you are probably using it as a kedge because it is inherintly inferior...

We have a Fortress style as a kedge.... and I have never used it.....


BTW.... if you ever want to sell your finngulf.... please give me first dibs.

Anchor choice

We sail our 25' double ender on the west coast of Scotland and changed from a CQR which in wild conditions had rolled over, and reset but we had lost ground and had to reanchor. We got a Spade, must be about 7-8 yrs ago when PBO did their 2 edition test on all types available then.
We went for an alloy version for the next boat size up, which was the weight of a steel on for a 25'.The performance has been absolutely top notch, the only problem so far was in Eriskay where the seabed had the consistancy of cold custard; the soon vacant buoy settled that!. we have since got a smaller alloy spade as a kedge which is easy and light to work with. Spades are not cheap but we consider it's been money best spent on Feshie in the 12 years of ownership.

If you want to keep the weight out of the ends of the boat , the first thing to tackle is the 150kg or so of chain that you carry. Particularly in Scotland where swinging room is usually a bit less of an issue, you could help yourself a lot by having (say) 20m of chain and 30m or rope for the main anchor.

Recently been up your way in a 13 tonne boat using a Fortress as main anchor. Bit first time every time and was light to handle. Withstood some serious wind. Only issue was the kelp where it always dug through and held but wanted to bring a lot of it back up when weighing anchor.
 
If your existing 10 kg Delta has always held you for the past two years and it is easy to handle why do you want to change the set up?

We have a similar set up on our Moody 31 and yes we have looked at Spade anchors in the chandlers down here but I am not convinced they are substantially better to justify the the high cost. Note the difference in size recommendations between the Rocna and Spade in our boat range. Rocna 10 kgs and Spade 15 kgs.

Two anchors

Since I got above thirty feet all my boats have carried two anchors but Ithese days I regard the second one as a reserve anchor rather than a kedge, In my racing days we had a light kedge on mainly rope which we could drop and lift again without losing too much way when trying to beat a foul tide but I don't do this any more. Perhaps I don't need a second anchor at all?
The Bruce is just too large and heavy to be of practical use in this boat in any normal situation but I envisage that if I lost the main anchor, say by another boat dragging over it; which has happened, I could manhandle it over the side from the cockpit where it is stowed in a locker.
I intend to follow the suggestion and look into the alloy Spade, but what is the advantage over galvanized steel of the same weight, I suppose the bigger volume would increase resistance but then make it bulkier to manhandle?
 
Kelp

I've said it many times on these forums, but I will say it again - the Spade is remarkably good in kelp. We always anchor first time in Canna Harbour - 'nuff said.

We have had CQRs, Bruces, Fortress and Spades on Rival Spirit.

Without doubt the Spade and the Fortress out anchor both of the others, CQRs and Bruces hold once set but setting can be a real drawn out process. On balance, the Spade is the most useful as it is more easy to stow and probably sets more easily than the Fortress.

Personally, I'd go with the steel version of the Spade purely because the additional weight should enable it to bite. We have had some probs with the Fortress which is lighter in weight and sometimes has difficulties setting, which the Spade does not suffer from.

The Rocna for one has an efficiency factor of approx 1.5 compared to the Delta, which means that you may reasonably expect a 10 kg Rocna to compare to a 15 kg Delta in the vast majority of sea-beds. That's from independent testing, not some invented marketing logic. This may stray from official recommended sizing, but if you are happy so far with the 10 kg Delta anchor, then this may inform your decision to up-size, or not, along with the switch to a superior type.

Whatever you do, don't make the common mistake of comparing different manufacturers' sizing charts. They are all done according to different criteria. Here is Rocna's info: www.rocna.com/kb/Rocna_sizing_recommendations

I had seriously considered the Rocna or Manson but the big tubular roll bar looks awkward for getting the anchor under the pulpit and stowing though I suppose it can be used as a handle, however Rocna's response to a recent poster with a galvanizing problem seemed decidedly lukewarm ( they offered to re-galvanize rather than replace) and again you cannot examine or handle the product until you buy it (though I understand you could make a paper replica of the Rocna, the weight and balance would be hard to replicate).
All Rocna anchors have a lifetime warranty against defect, plus the majority of resellers will support a no-questions-asked money back guarantee. If there is any problem with the anchor it will be replaced, you need not be concerned with that, and you will be quite able to ensure the anchor fits and works on your boat without risk. Regarding the latter, the patterns you mention are available just for convenience - e-mail Rocna asking for them.

Would anyone like to comment again on a suitable anchor taking account of performance and handleability or should I start saving close to £500 for a Spade.
Look into feedback on the Rocna re kelp and weed. It is sure to out-perform the Spade in all respects, particularly kelp etc.
 
Anchor choice

C'mon guys, I would like to read some independent response to Craig above.
Surely the Spade on which the Rocna is based is not as inferior as he says, it looks much neater than the Rocna which is one ugly piece of engineering, though I admit the Delta shank as copied on the Rocna works well on my narrow roller. However, if I did decide to go for a roll bar anchor I would buy a Manson, at least they have taken the trouble to find an outlet in Scotland. I don't like the slot in the shank but have never heard of it causing a problem?

Have you used a Manson or Rocna? I have used Bruce, CQR, Delta, Fortress, Manson Supreme. I have to say that (I think) you are totally wrong, they set on the first spot they touch. In 3 years I have never had to do a reset. I would never go back to any other type.


Oh Bugger - I have just fallen for a trole!!!!!
 
If there is any problem with the anchor it will be replaced, you need not be concerned with that

As the subject of the earlier referenced rusting Rocna, that option was not offered to me by your production manager, just re-galvanising, which will be a long drawn out and tedious procedure for me when I get back to Italy (and the anchor) in September.

However, it is still the procedure that I prefer, because my testing with further impact points to establish the rusting cause, showed the galvanising just flaking away leaving bare steel; this convinced me that the galvanising was not effective - can I be sure that a replacement would be any better?

Hi - as you see from Craigs post, he has a habit of slagging his opposition. In my opinion the Manson, is a tidy piece of engineering, compared with the Rocna, which is why I bought it. As for the rock slot, Manson say that the Anchor shank is way over strength, so the metal lost is irrelevant.

Rocna is now produced in China, and there are rumours that it has a cast iron fluke welded to a steel shank (not a good idea apparently). I have aksed Craig to clarify this on a number of occasisions, and he has not replied, so I can only assume its true. Craig - perhaps you should clarify this for us please......

You should be able to trial fit the anchor at the chandlers perhaps????

I'm independant in this matter. But having had a galv plant in my last factory, you cant be sure that re-galv will work. There are some steels which contain tramp elements picked up from the scrap and which wont reliably galvanise. It's a rare occurrence but not unknown. More likely your galv problem is just poor galvanising in the first place (dirty spots on the steel surface most likely) and if properly cleaned and re-galv it will be fine.

In your place I would insist on replacement. The anchor as supplied was faulty.
 
The French magazine "Voile & Voiliers" did an anchor test in their July issue where they wanted to test the new generation of anchors against the traditional ie the Brittany and CQR anchors. They used a lifeboat with more than 3 tons pull and in addition they filmed the results underwater. Most of the new generation were there but a notable absentee was Rocna (my own favourite). They tested anchors around 15kg on different types of bottom (hard sand soft sand mud gravel) and also pulling at different angles 0° up to 180°. They then measured the break-out average of all of this. Spade had the best results of the steel anchors at 1237 kg with the comments (For) "By far the best holding in sand" (Against) The tip is less pointed. Perfectible on hard bottoms, high price €520 " There was a special mention for the Kobra 2 1160 kg (For) Excellent conception, hooks rapidly and precisely, price €174 Certainly the best quality / price ratio. THE good surprise. (Against) We're still searching.

Incidentally CQR had the worst results at the highest price. 285 kg €890. This result surprised them because of previous better results and wondered if it had anything to do with the manufacturing of this particular model.

FWIW

John

Incidentally the aluminium anchors produced excellent straight line holding but were liable to be twisted on high lateral traction. The Fortress 10.5kg American anchor held to 2250kg €670 but was cumbersome and difficult to store.
 
How do you work that out?

Look into feedback on the Rocna re kelp and weed. It is sure to out-perform the Spade in all respects, particularly kelp etc.
I find it hard to see how the Rocna can do better than set first time every time anywhere and never drag, which is what our Spade does.

I don't see the point of Rocna getting into a p*ssing contest with Spade - I am sure they are equally effective, it is more whether you want the roll bar or not. Otherwise, competition would seem to rest on matters of price, manufacturing quality and availability.

Barnacle, talk to the distributor, a satisfactory outcome will be found for you.
Easier written than done. I bought my 15kg Rocna anchor from the then only European distributor available to me in Switzerland, Rosch Marine of Zaandijk, Netherlands, in November of 2007. They are no longer in your list of distributors. At that time there were no Italian distributors where my yacht was moored.

But why should I do that? I have already written that I have no confidence that a replacement would be any better and to ship back to Holland from Italy would involve me in more shipping costs above and beyond what I have already paid, together with Swiss taxes, import costs and duties.
