Very interesting article and also very odd - That the Fortress did so well and the West Marine carbon-copy did so poorly. It seems strange that the geometry being so similar (especially compared to how different the other makes were) and the only real difference mentioned was the sharpened edges. Even though most of the other makes don't have those sharp edges like the Fortress.
Anyone know more?
They also said that all of the anchors set when a smaller vessel was used. Like you, I find the methodology suspicious when two, virtually identical items perform so differently.
At any rate, I've had the same experience Jeff stated with my Fortress. Always holds in sand. Not good in muck/biomass/grass, unless you want to dredge with it.
I was completely clueless, but I bet you knew about adjusting the angle... have you ever tried the other angle in that muck?
I'm not Jimmyt, but I have tried my Fortress with the wrong angle in both bottom types.
At the 'mud' setting, which is 45° fluke angle, it wouldn't bite into sand. It would drag some skid marks, but not start diving.
At the 'sand' setting, which is 32° fluke angle, and is what pretty much all the Danforths and knockoffs use, it would dig into the mud, but stay shallow and just pull very deep skid marks in the mud. Never really holding.
Weed bottoms are a problem no matter what you use, but single point, plow or scoop types, fixed shank anchors seem to do the best. Better with no hoop, but I'm not sure that's a significant difference other than the effort required to clean it afterward.
You can still buy CQR anchors, and there are cruisers who swear they're the best (the
best!), but I have a hard time believing that the first small boat anchor that wasn't a fisherman style (the classic U-fluke "anchor" shape), which started life 90 years ago when Bonnie and Clyde were robbing banks, is still the state of the art, especially given the known difficulties in setting and resetting. And they're
expensive by comparison to just about anything else.
And on the subject of bottoms, the size of the anchor matters. Weeds and rocks are a problem for any small anchor. They don't get smaller when the anchor gets smaller. But plop a navy stockless anchor, like on a big ship, onto that bottom, and it won't even know they're there. The little stockless anchors you can buy for small boats are about the worst performing anchor there is, but that's because they were never intended to be made that small when they were designed. A 30,000 lb Navy anchor doesn't scale down well to a 10 lb stockless for a small boat. Well, it scales down just fine, but it won't hold in anything, and will work about as well as a lump of lead.
So both anchor type and bottom type do matter, and there is no 'one type fits all' anchor. For my purposes, and this is my opinion only, the Fortress is best suited for my sailing grounds, and for storage, since it fits in the locker along with 25 ft of chain and 200 ft of 3-strand rode. It's light, easy to handle and deploy/retrieve, easy to store, and suits the bottom types I normally see. Not as good at resetting with wind shifts as other types, though, but I never overnight at anchor on this boat.
BUT, if I had a bow roller that could store the anchor, I'd use a next-gen scoop style, like the Rocna, Mantis, or Manson Supreme, or the hoopless, specifically the Spade. Rocna and maybe others now have hoopless styles also, but I don't know how well they perform. I've had a Bruce on my big boat, but it didn't hold well in mud. Held great in other bottoms, though. Mud is always a problem, for anything but a mud anchor, and even then, my little Fortress can bury itself so deep I almost can't get it back out.
Sorry for the term paper, but the coffee is flowing and I'm bored at work.
