Re: Practical Sailor anchor testing
I've done a lot of instrumented anchor testing for articles, books, and my own curiosity. It's like herding cats. The short version is...
* If the bottom is good sand or sticky mud, everything holds and the data is consistent in any given location... but it will vary with location.
* If it is a difficult bottom (soft or hard), the data is all over the place. How soft is the mud? What is the density gradation? Is it layered with shells? Are there tree limbs in it? What is the pull rate (it makes a HUGE difference during setting)? Are there rest periods (big difference)? A LOT of repeat testing is needed.
But if the data is all over the place, that means that real-world performance will be too, since we are not machines and the bottom varies. Cruiser anecdotes aren't any better, for the same reasons. Thus...
The best you can do, IMHO, is read a lot of data, and then learn how to set and test an anchor properly. The truth is that you can safely anchor with most any anchor, if it is sized properly and you know how best to use it. We all have our favorites, and I'm not going there!
