Thank you Bill! Indeed... I love my cheap Bruce knock off aka claw
A quality danforth has very good holding power but I find that they don't always reset on a wind or current change as they often clog with mud and weed..
I ve been using a claw for 5 years on the boat I run... Originally I put a 110lbs version which would run out of holding power at about 35 to 40 kts. 3 years ago I replaced it with the next size up, 176 lbs and it has held me up to 60kts... (70' enclosed flybridge boat = high wind age)
I have used it just about everywhere from the cape cod area all the way down to the Bahamas, in all kind of bottoms. We anchor a lot, probably an average of 10 to 15 times a month and I think it failed to set on first attempt just twice in the past 3 years. It is literally drop, set, check and forget it.
That said, I think there is no such thing as a bad anchor... Yes, some anchors don't do well in some bottom, for instance a delta in soft mud doesn't have much holding power but usually the problem is not the anchor, it is the retarded captain who is incapable of multiplying the depth by 6 or 7...
And with the claw costing a fraction of them fancy rocnahs, spades etc... I know Bill will be along shortly to tell you picking an anchor based on price isn't a great idea

and he will be right, but in the case of the claw the cost if just an extra bonus
