latest anchor test

One of our favourite pastimes, while lurking in the sand dunes avin a barbie

Salinia:
Is that the new Spaniel Dynamic Anchoring system?
I've got a similar one but it doesn't reliably sit, stay and hold a position and objects strongly to being used in wet conditions, preferring to return to the "anchor well", and curl up.
The other downside is that the SDA can't be left on board unsupervised as it will self deploy to chase anything that it imagines or sees.

'Skipper' has many talents. He can be seen filmed here fetching essential supplies from the anchored vessel to the shore party.

Bow roller was fitted in the UK after the boat arrived from Sweden with a naked bow (as was anticipated). So there's someone not far from the Hamble who can make and fit them. Want me to ask who?

If it's not too much trouble I wouldn't mind knowing. I was really hoping for a shop selling many varieties of the extension on their own though </hopeful>.

For those who have not seen the article a brief summarry of the results follows
Best first. ( efficiency rating is the figure given)

6kg spade 24
15kg spade 32
4 kg Rocna 21
16kg Rocna 30
7 kg Manson Supreme 12
11 kg manson Supreme 21
7kg Delta 8
16 kg Delta 11
7 kg CQR 7
21 kg CQR 8
6 kg Bruce 5
16 kg bruce 6

These tests were all conducted in medium/hard sand which seems to be a basic weakness with the survey ( as has been pointed out). The author notes this point himself and is clear that different sea beds would affect the results but maintains that the 'order of performance' would be significantly the same.
The CQRs problem was attributed in part to the hinge which caused/allowed the anchor to snake around.

No mention of the XYZ anchor "http://www.xyzanchor.com/" - video looks pretty conclusive!!!

I don't have any evidence to support this theory, but reading hundreds of anchor threads on many forums suggests that heavier CQRs and Bruces perform far better than the lighter ones, under, say, 35 lb. Many of the owners who swear by theirs, quoting months of anchoring in serious winds, turn out to have bigger boats with heavier anchors, and often with oversized chain.

I think Viv has a good point.
I believe there is a scale effect.
The anchor manufacturers believe, and advise, with an appropriately sized anchor we are equally secure. I do not think where there is weed, for example, this is necessarily true.
This is not surprising, the size and resistance penetrating weed does not change as we alter boat and anchor size.
To a 10Kg anchor a weed root may be a major obstacle preventing setting. The same design anchor in a 50Kg will not see the weed root as a similar problem. I have snorkelled over many 100’s of anchors, observing their performance.
My observations are the larger anchors set better. I have also observed larger boats drag less often than small boats.
This is true of all anchor types, but is particularly noticeable with Bruce anchors. Large Bruce anchors (say 40 Kg and above) seem to work well. The smaller anchors do not work as well especially in harder bottoms or weed.
The CQR seems works poorly no matter what the size. It rarely sets well in difficult conditions so its difficult to discern a pattern based on size.
