Because of their light weight I would be inclined to get a larger than recommended anchor to get a larger fluke area.

"One aspect of the Danforth anchors I've wondered about modifying is the pad that pushes the back end of the anchor up to produce the angle of attack that promotes or facilitates setting. Perhaps they'd dig deeper or set more readily. A steeper angle trailing edge could be added ......."

Eric you are on the right trail but going the wrong direction. There is a flaw in the original design of the Danforth that was corrected in the Danforth Deepset and Fortress anchors. The pads need to be parallel with the flukes.

The angled pads do help force the tips into the bottom but when the anchor is buried up to the pads they start to kick the rear of the anchor up and it won't bury much deeper.

Many years ago when Danforth introduced the Deepset anchor they made small scale models of both a standard Danforth and the new Deepset Danforth. They brought them and a large aquarium to a trade show I attended. The aquarium was full of sand and water. They would let you pull the model anchors through the sand. The standard set quickly but would not penetrate very far and it was possible to drag it through the sand. The Deepset Danforth would just keep going deeper into the sand until you couldn't pull it any more. It was a very dramatic difference.

They had production problems with the Deepset and it never really caught on. I don't know if it's still made or not.

Nice one Hendo. Trouble is out Northern Hemi cousins are at present finding it hard to source them. Rex Francis of Anchorright is trying to fix that, but not sure where that is up to.

Eric, I think you and Hopcar might have been close re the puzzling superiority of the Fortress over the Danforth types. The angle of the pads, or flanges, which is more like the Deepset design of the newer Danforth Hopcar mentioned, (though not parallel, I would think, or they would not dig the flukes in at all), but a bit flatter angle so it digs in further, and the fact that the alloy metal construction of the Fortress means it can be sharpened more where it counts without corroding, as not galv. coating dependent for its anti-corrosion properties, so does cut in better. Otherwise, as you say, there should be little performance difference, and what difference there is, should favour the heavier steel Danforth type.

Its certainly a major factor.

David: Do you have 2 chain lockers on your boat? I keep my spare (Danforth) in the starboard locker with line attached. If I had to, I could deploy the spare by hand with the use of the capstan on the windlass. This is very comforting when you consider all the anchoring I do.

Chip it looks like you're scar'in those poor dogs half to death.

The ABS connection makes it really funny.

GOOD one Chip.

Good Grief Anode, they`re not natural water loving dogs, are they?
I second Hendo and PeterB on the Sarca, loving ours. But I can understand that exporting something that heavy and odd sized is going to be a challenge.
Interesting, I saw Sarcas stocked in BCF, a few days back when I bought my kayak.

It seems odd to me that a lightweight aluminum anchor should out perform all the steel anchors of the world but they do ... including all other Danforths.

That is because "efficiency" is being compaired by the pound.

The Danforth and every other anchor needs a certain amount of AREA to grab the bottom.

A 35H or 60H Danforth should be compared to a similar aluminum anchor by its size , not the weight.

Since the weight gets the anchor down thru the weeds on some bottoms , I prefer steel to flyweight as the windlass brings it into the bow roller , not hand over hand recovery.

A Forteress would be a fine hurricane anchor , as these are usually huge, stored below , brought up before a storm and set in the best sand bottom one can find, with a special storm rode and chain and chafing gear.

For most cruisers a Danforth H , or slightly heavier CQR seems the first choice for indifferent bottoms.

Since just about the only complaint about Fortress anchors is its ability to reset if the wind changes, I would have thought differently.

Walt: I have only a single locker and its too small for an anchor and barely large enough and deep enough for one chain rode. I keep the Fortress in the Lazarette and its Brait rode next to it in a milk crate. I can have it out and over fairly quickly, but not as quickly as if it were ready to go on the foredeck.

Since this pic was taken, there is now a roller on the anchor platform in line with the bitt for the Fortress rode or our mooring pennant.

With no windlass on the boat and given our bottom type, it made a lot of sense for us. The reset issue hasn't been too bad, but we do keep an eye on it (set alarm to check anchor around time when tide changes). All that said, we would probably go with a different anchor were we in an area with grassy, rocky or coral bottom. The Tug came with a Delta, which we like, but is not as good in the mud. The Tug also has a Fortress backup.
The anchor test that tested the performance of anchors when there was a big change in the direction of pull like when the wind changes measured the fact that certain anchors stayed buried and all others either moved a bit or broke out and reset or broke out and never reset.

The anchors that stayed buried and didn't move over 12" were:
Spade 80
Super Max
Danforth Deepset II
Fortress
Bruce

If you look at the anchors listed you will note they have sharp points and edges and the angle of the flukes are more aggessive.

So now I have to modify the Danforth also. Well luckily the plant can grind down the point and edges and weld an additional piece to the Forjord Fluke and raise the height of the Danforth’s pad.

Speaking of pics, It sure would be great if you could post more of them. You have one of the best looking 32's I have ever seen and it's a Euro, which I covet.

Here is a Forfjord w mud flukes.

I thought they were owner add-ons but I've noyiced most are all the same and look professionally done so I suspect they are a factory option.
