A problem I've had with no windlass after a bit of a blow is getting the sodding thing out again.
Sailorman, sorry to hear that. A couple of simple performance notes which might make a difference:
• Be sure to permanently install the Mud Palms which were included in the box, as they will lift the back end of the anchor up so that the flukes take a more aggressive angle into the sea bottom. The Mud Palms typically solve any setting issues in common sea bottoms.
• Be sure that you do NOT have the anchor set at the 45° angle, as this angle is only to improve the holding power in very soft, silty, soupy, mud types of bottoms. If the bottom is a harder soil as you described, then the anchor is likely to skip along the bottom and not set at the 45° angle.
Please let me know if this helps!

Hi Ed,
In a word, sharpness. The shank and flukes of the Fortress anchors are precision-machined to be sharper than heavier, dull-edged steel anchors like the Danforth, which typically results in faster and deeper penetration into a sea bottom. Kind of like a razor cutting into something vs. a dull knife.
That said, there are certainly sea bottoms where a denser anchor with a narrow single fluke might have a better chance of penetrating, such as grass, weeds, or rocks vs. the two big flukes of the Danforth/Fortress types.

Dear brian
all fitted as per the instructions with the exception that i deemed it seaman like to use duralac on the ss boltsfor obvious reasons.
i never "chuck-out" loadsa chain but pay it out carefully.
the first time i uesd it set at the second attempt then held.
The next time single handed it failed to set at all. i went out into the river & changed to the trusty Bruce went back the the same anchoring spot & the Bruce set first time.
Brian
what do you suggest i do with this anchor that fails to set
Sailorman, it is a bit baffling as to why the anchor is not setting given it's sharpness, once again, unless:
• The clay bottom is hard as a brick, so the much denser Bruce can get some penetration into it.
• The boat is falling back too quickly and not giving the anchor much of a chance to dig in.
I might try setting the anchor initially with a shorter scope, like 2:1 or 3:1 to insure that the shank isn't somehow sinking below the flukes from the heavy weight of the chain. In this case, the flukes end up pointing upward instead of downward into the bottom.
This typically cannot occur when the Mud Palms are installed, as they force the flukes downward, but please give it a try and let me know.
Thanks,
Brian
just prior to changing back to the Bruce i did exactly that.
will try again,well before the 90 days![]()
Don't be overly concerned with the 90 days, I will work out a refund with our local distributor / retailer where you bought it beyond then if necessary.
Some good, some negative posts, for my tuppence worth they are great anchors.
If it isn't setting then I would take a look at your anchoring technique, they ain't the same a big heavy Bruce or plough anchors and they do require a different approach to anchoring. The chain hits the bottom quite a bit before the anchor and it doesn't set if you try to anchor as you would with a big heavy anchor. Let it out nice and slow allowing the anchor to 'bite' then lay the chain out as slow as condition allow, have a brew and then go astern and dig it in; should hold now.
We carried an FX11 as a kedge and used it loads of times with great results,only having a problem retrieving at times. We bent or main anchor (20Kg Delta) in Ibiza so used or spare Fortress FX37 as our main anchor for the rest of year. Admittedly it's on 10mm chain right through, but after getting used to a new technique of anchoring it held us without any problems.
We again used it in the Canaries in soft sand or ground where the Delta doesn't hold, no problems at all even during wind shifts and gusts you associate with the Canaries.
In the river Gambia (3rd biggest river in Africa), plenty of tide/current up to 5 kts at times and very soft mud, our Delta was a waste of time; the Fortress was brilliant. Held first time every time, never pulled out, never dragged. The biggest problem we have had with it is getting the thing back as it sets so well.
Our little FX11 held us once in squall hitting 45kts at times for over 30 mins no problem, the Delta went walkabout!
Fortress anchors, they do what they say on box.
Brian - bit cheeky to ask perhaps but would you mind recommending the right size for me? Given all the replies (I'm the OP) I am almost certain that I will be trying the Fortress: even if, say, something else held better under some circumstances, it's not that great if it's so heavy I can't use it. I'm going to make a cardboard model of it to make sure I can stow it on the foredeck, but I don't anticipate it being too much of a problem. It's unlikely that it will fit on the bow roller as I have a bowsprit, but the same would apply to lots of other anchors, and at least the Fortress is flat and I should be able to pick it up - I think it will tuck away under the inboard end of the bowsprit.
My boat is 31 feet LOD, but it's old (1930s and wooden) and heavy - I think about 8 tons. The FX 11 says it suits boats up to 32 feet, but that probably means of average weight. I'm assuming the FX 16 would be the best bet, though a previous poster says your sizing is very conservative.
Robspop, I would recommend sizing up to the FX-16 if you are likely to encounter high winds (30+ knots) and poor holding bottoms like soft mud. There's not much of a weight gain either from the FX-11 to FX-16 to strain your back, just a hair over 3 lbs / 1.5 kg.
I can send you a drawing with dimensions if you like for a cardboard model. Just send an e-mail with your address to brian at fortressanchors.com

Brian
