Help Please, Anchor weight Beneteau 411

[Neeeil]

Hi I am looking to upgrade the ground gear on my 1999 Beneteau 411 and was wondering if anyone could advise me about the weight of anchor I should use?
I have spent hours looking at all the feedback on Anchors and think I will go for a Rocna, when i look at their graph of suggested size my boat falls between a 25kg and 33kg anchor.
The windlass is Leroy Somer Electric Windlass )I don't know the model) my 411 weighs 7.8 tonnes and is 12.6 meters long
I would be grateful for any help
regards Neil

I always go for the largest in the recommended size range. (Or even the next one up)

I think you are looking at least the 25 from the Rocna range

or something like a Fortress FX 23 at 7 kg. (though I am not too keen on the adjustability function, preferring to chuck something over and know that you are going to stop.)

Hi,
We replaced the Dufour standard issue 16kg Delta with a 20kg Rocna earlier this year, the boat is a Dufour 40, and is quite bit lighter than your boat, however she tend to shear around at anchor a lot when the wind picks up. The 20Kg Rocna is just about the biggest that would fit and looked OK from the Rocna sizing chart.

The Delta held well when it set, but was often difficult to make it set because many anchorages on the West Coast of Scotland have kelp to some degree. The Delta would get dragged across the seabed and quickly “clog up” with kelp which prevented it from setting. The anchor would then have to be raised and cleared of kelp, before having another go at anchoring. The Rocna sets very quickly, and we’ve only had one problem anchoring with the Rocna this summer, where the seabed was obviously solid rock form the scrapping noises coming from the anchor and chain.
So a 20kg Rocna may well do, but I’d go for the 25kg version if it fits.

You are in a tight anchorage. It is night. It is raining. The wind is squally and the boat is shearing around.

At this point NOBODY says " Our anchor is too big, I wish we had purchased the smaller one. ".

According to Benneteau themselves, the 411 weighs in at 7.8 tonnes not 13.93 which is rather more likely since even a Moody 42 ( not noted for high tech light construction) displaces just 10 tonnes. I would have thought you would be fine with the 25kg

Seems you have been tuned in to this, or many other sailing fora lately!

Rocna has scored a serious own goal by moving production to China and knowingly using steel below it's own spec. Talk of law suits, etc.

He need a Genuine S&L 45Lb C.Q.R end of story

Thank you everyone for your comments, checked the boat weight and Bosun is right I had the weight all wrong 7.8 it is this, should make things easier, I am currently using a Danforth type anchor, which came with the boat, it has no markings on it but it's very like the Fortress, however like Ian Edwards Delta I think it skips along the bottom before setting.
We had a close call in Loch Tarbert on Jura when we dragged the anchor in a howler, when we managed to recover and reset the anchor, I put on a mask and fins and checked .
The bottom was hard sand, small stones with kelp patches, it had dragged before setting and packed under it was a pile of kelp not enough to stop it setting but enough to prevent it from burying itself properly.
I am pretty sure this is what had happened the night before even though we had a very positive bite when we set the anchor it was only partially set, eventually it broking free with the boats movement, dragged and picked up more kelp and we were in trouble.
I think I will sleep better with a quick setting anchor something that will set before picking up the kelp, but I am still going to dive and check it whenever I can.
Not sure I like the sound of the Rocna cheap steel! I looked at the XYZ web site www.xyzanchor.com their promotional video and blurb is pretty convincing has anyone any experience of these anchors?
cheers Neil

I think I have answered my own question about XYZ anchors all their feedback seems to be based on soft bottoms not ideal for the west coast of Scotland

The best hi-tec anchor alternatives to Rocna seem to be Spade, Manson, Bugel.

My 411 came with a 27kg Bugel ( similar to Rocna but cheaper I think).
It is without doubt the best hook I have ever had. Used mainly in the Ionian and has held well in 30plus knots in mud, weed and sand.
I`m sure i t is heavy enough and my Lofrans 1000watt tiger pulls it up no problem.

One of the best defences against kelp, is a fish-finder. Mine gives a very clear indication of the cleanness of the bottom. But what would I know, I use a Bruce!
