The equipment that attaches your boat to the anchor is the second part of the discussion of anchors and anchoring. Here is the article that starts the discussion:

This online newsletter from MyBoatsGear.com contains a comparison chart of the top anchors on the market: http://myboatsgear.com/newsletter/200788.asp The anchors chosen are the Rocna, Fortress, Delta, Spade and Supreme. Each of these anchors had the highest holding power in a variety of tests performed by various publications and organizations. The chart compares holding power, cost, weight, type etc. RSS feeds are available at http://myboatsgear.com/mbg/index.asp
It looks to me like the language chosen on MyBoatsGear site has been cleaned up a bit so as not to slant entirely toward Rocna as it seemed to before. The previous presentation knocked the Manson Supreme unfairly, imco.
Much of the text about the anchors is taken from web sites, therefore it's NOT impartial. Advertising copy is used to describe the named anchors.
Some of the slant still appears in the "impartial" individually rated description of the Manson Supreme where the long slot is said to be a hazard because chain will get caught in it. This is nonsense.
This shows what happens when info is copied from other sources.
In the past the text also read that the long slot weakened the Supreme shank. That opinion is no longer there (or I didn't pick it up on scan). Originally the opinion came from one of the Rocna sites.
What POSSIBLY can happen with ALL roll bar anchors: Wasi, Rocna, Supreme, is that chain might get caught/wrapped in the groove between the roll bar and the shank.
No tests, photos, complaints exist for this scenario so far as I know. And it seems unlikely. No tests so far.
Remember, the Sarca anchor adds a piece from the top of its rollbar to the shank so chain can not get caught in that space.
You will notice that the Supreme does well in veering tests - while the Rocna does NOT.
I believe the Rocna design, while quick setting, is not able
IN THE WEIGHT ANCHORS WE USE
to take a deep set.
The Supreme, because its fluke is curved but FLAT is able to penetrate deeper and therefore can be pulled by the boat into a new position while still buried.
Of course I have done extensive testing comparing these two anchors IN MY MIND. But actual on going testing is proving this conjecture.
Imco Rocnas share some of the problems of the 'cup' shaped claw/bruce anchors in that they can grab a piece of the bottom and pull out.
Of course the scoop shape of the Supreme could possibly do the same
BUT my feeling is that the design is more likely to want to dig deeper than to set shallow and pull out. The Rocna anchor has angle bends in the back of its fluke which PREVENTS DEEP PENETRATION.
[Imco the rollbars attached to the rear of the fluke may also limit penetration - along with the welding gussets (which are on the underside of the blade in both anchors) that strengthen the pipe's join to the blade. imco these projections also can seriously impede penetration.
But this is not from my actual experience.]
I think this is an important distinction, even if eyes glaze over.
The writer on the MyBoatsGear site also does not seem to write from his actual experience. It's all collected from print data.
But there is a great deal of data on gear necessary to get an anchor system together.
Much like the majority of posters on the internet. :DQuote:

Real testing by real cruisers is about the only thing I pay attention to regarding anchors anymore.
And Craig, I once did trip over my elbow while crawling below almost broke my nose;)

Maybe ole Henry David was checking on some postings too ;)
Now...back to anchors......................
Now there is a great mantra!
