So, why talk more about it, at least before a new generation of anchors appears to be tested against the better ones?
Good point. I just posted the below on a different forum in response to a "new" generation anchor manufacturer. This holding power test pitted "new" vs. "old" generation anchors:
The 40,000 member Swedish Cruising Association has been conducting anchor holding power tests off of their coast for over 20 years. They take boating very seriously over there, as 1 in 7 Swedes owns a boat.
Below is a link to a page with the results of a test that they conducted this past summer in a clay bottom near their shoreline:
As you will note, the new generation Ultra and Rocna anchors only achieved 2 stars out of a possible 5.
The other roll bar anchor, a Bugel, which I guess is an old generation anchor since its design has been copied, achieved 3 stars, as did the old generation Danforth anchor.
You might find the results of the other anchors tested to be of interest as well. I am working on an English translation and I hope to provide one shortly.
