Rocna Doesn't Fit . . . Do I Go with Ultra or Delta ?

I'll get the 33 then and upgrade the chain later. I suspect that your size recommendations, besides being a little more thorough (displacement & weight) are a little more conservative than others.

Read this re Rocna sizing:
Rocna sizing recommendations (Rocna Knowledge Base)

I think the 33 is good for your boat. No need at all for the 40 unless you plan on more distant / risky cruising in tough environments, in which case the BBB chain is definitely no good either.

After another season, I have two more data points for the anchor wars:

I was in Newport a couple of weeks ago, and the predicted a gale from the SW. I ran up to Potter's Cove with a 42' cat, and dropped my Bugel in 12' of water with 100' of chain. It set fast and hard in mix of sand and shell. The cat had a Delta (he said it was 35 kg), and after 3 tries he gave up and I helped him grap a mooring. He said he also let out 100' of chain, and his technique looked OK.

I was on a friend's boat this summer and noticed that he had a brand new aluminum Spade. His old one had started to delaminate after 10 years. He showed it to the Spade folks and they gave him a new anchor at no cost.

I finally figured out the chain is 10mm DIN 766.

Next problem is, as I now see, I have the same issue as the OP. A bow sprit with a hole in it that will accept the shank but not the hoop.

So, it looks to me like the shank will stick up in the air with the hoop on the underside of the sprit.

Now I'm not too pretty either and I can't see the anchor from the cockpit so, astetics aside, what are the down sides of that kind of installation? Is there a real danger of anything bad happening?

Is there a suggested 'fix'?

[craigsmith]

Rocna have generalized suggestions here:

Lowering the roller on extended cheek plates sounds like the most obvious and easiest 'fix' if you're willing to make mods at all. Otherwise some folk are happy with the arrangement you mention, witness the pics in the article above.

E-mail Rocna and ask them for their dimensions / patterns if you want to check the fit for sure.

We will be pleased to send you a paper template of the Ultra Anchors you are considering to see how they fit in your bow pulpit arrangement. Or we do have some pretty detailed dimension drawings on our website.

I am seriously considering the Ultra for my Jeanneau 54 to replace my Delta 44lb. Just not sure what size, 66 or 77lb. My biggest concern is wind shifts.

[Dockhead]

Try a Spade. Equal to Rocna or Manson, vastly better than Delta. High cost is the main downside; otherwise a perfect anchor. Without the roll bar, it should be easier to fit.

This is my second year with an Ultra and it has never let me down in the great lakes. Caught every time the first time.

It has held in 30mph winds and 4 to 5 ft waves in a sandy bottom, biggest test I have had for it so far.

Mine is a 58 Bluewater, weighs 54000lbs and I have a 77lb (35kg) Ultra.

Thanks for the replies. Ray Sea, have you experienced any wind direction shift while using it?

Not much more that 20 degrees, however, if it did shift more than that I am sure the anchor would reset quickly.

[GMac]

Ultra, no question..... bar the price difference which is a little in the Ouch region. They do reset very well.

A 60lber.

[Somewhere 54]

Thanks GMac. The boat fully loaded is just under 25 tons so a 60lb Ultra should be okay?

[Quickline USA]

Regarding wind direction shifts, Ultra Anchor has received ABS (American Bureau of Shipping) certification for Superior Holding Power (highest ABS gives, 4 times greater than ordinary anchors) based on testing in real conditions, design review and load testing(both laboratory and field testing). One test not included by ABS is changes in direction pull, but observed under actual conditions the Ultra Anchor actually rotates below the sea floor surface and does not have to reset. If it did surface it would reset immediately. The real condition testing for ABS Certification was under direct pull with a tug boat that under load strayed port to starboard while strain gages measured the load, not a complete reversal of direction but an indication of what happens in extreme wind shifts. I do have a commercial interest, I am the Western Hemisphere distributor of Ultra Anchors.

[Quickline USA]

We generally recomend the UA35-77 on the Jeaneau 54 DS per our "Anchor Selection Table" (anchorsizes.pdf) on our website, though some Jeanneau 54 owners have elected to stay with the UA27-60.

Randy, Does the 77lb Ultra fit the standard roller on the Jeanneau 54DS without any modifications?
