I am looking to replace my 15kg Delta style that takes some distance to set in hard sandy and drags through soft mud.

Has anyone either of these sizes on a Beneteau 343 or similar?

If the 20kg fits would it be useful to have the storm anchor on the bow or would it just look silly?

I am not near the boat so cannot test a template until the summer.
Thanks
Andrew

Big as will fit - you will never wake up in a blow with a 20kg and wish you had fitted at 15. However I suspect the pulpit/bow roller may be too close to the bow to fit either so an extension my be needed
 
We had a 15kg Rocna on an Elan 362 (circa 6 tons), used in the Scottish West Coast. Used extensivlely and never dragged in the time we had it (unlike the Delta on the replacement boat, which is now replaced by another Rocna)
 
For what it's worth, on a similar sized boat, I also had problems getting the 15kg Delta to set & replaced it with a 15kg Rocna, which I have used before on a previous boat.
It sets first time & has always held well on W. Scotland anchorages.
I went for the 15kg rather than 20kg as it fits my locker and bow roller. It's also light enough for me to take off the bow roller without too much strain, when I leave the boat for a few weeks on it's swinging mooring.
 
Interesting we have a 15kg delta on our Beneteau 345 on the scottish west coast.

Extensive anchoring all over the west coast ...never dragged once in 6 years...... touchwood

Wonder what we're doing different?

I really couldn't say: but the Delta sometimes bounced along the bottom for a good way before setting (& resetting) & so I guess I just lost confidence in it.
Over the past 25 years I have dragged quite a few times (always with a CQR: on my boat, charter boats and friends boats), and often had to reset. The only time the Rocnas let me down was when I impaled a scallop dredge on the tip. I still rate the Spade's fast setting and holding power, but the galvanising is poor and they don't fit my boat.
Each to his own...
 
The Rocna is a good anchor. Here's some test data (kg holding powder per kg of anchor)
Knox 42
Spade 32
Rocna 30
Manson Supreme 20
Delta 11
CQR 10
Bruce 9

Easy to see why you want to change from a Delta style (which might not even be a genuine Delta?)

I think we'd have to know a wee bit more about the test conditions before swallowing these figures from Knox anchors. :rolleyes:

Two key issues here. Obviously depends on your age / strength and design of pullpit but I found that removing my 15kg Manson ( a better made version of a Rocna) put me at risk if the boat was moving about a lot, and I doubt |I could have held a 20kg one out at arms length manouvering it under the pulpit into the roller. So I went instead for the Fortress which has served me brilliantly.

Nothing wrong with the holding power of the Rocna I first had or the Manson or for that matter the Fortress. But the latter is less likely to send me to the chiropractor.

By the way all these were on a Starlight 35 which is between 7 and 8tonnes. No way do you need 20kg on a 34ft Benny.

Did you not keep it permanently on the roller then? Like you I suspect I would struggle with and above 15kg if I had to manually handle it.

Regarding Delta versus Rocna - I suspect most Rocna owners have struggled to anchor so have upgraded (and that's not a value laden statement). Upgrading would shoot a long way up my priority list too if my Delta ever dragged in anger which it has never done once set. I would enjoy an anchor which set a meter away from where I dropped it, not 2-3 but that doesn't yet justify the much higher cost for a better anchor.
 
The 15kg is still giving plenty of oversizing, the 20kg would be overkill and do your back in. I helped a friend install a 20kg rocna on a Moody 422 and it was a handful but is a Mitch bigger boat and plenty of space on the foredeck.

We have a Jeanneau 342 with a 16kg Kobra which, touching all wood available allows me to sleep at night on the west coast.

At the end of the day, it all comes down to what you have confidence in and only you can make that call.
