I am sure NCC320 will say I am biased here. but why not test a more realistic set up.
---------Not this time. I agree. While I think Mantus has a great product from all I have seen or heard about owner/user results, I think they are missing the boat in convincing people of the value of their product.
Typical suggested test: 25 lb. anchors (or 35), 20-30 ft. 5/16 chain, 5/8 nylon rode, set at 7:1 scope, and again at 5:1 scope. Also, veering pull to 90 degrees after set. Record maximum pull (holding force), as well as distance to set.
While the above would be a better test, in the interest of time, for a quick and dirty test by hand with the 9 lbs. anchors, repeat those earlier shallow water tests with a 6 ft. piece of chain between the rode and the anchor. No one that I know anchors without at least a bit of chain connected to the anchor. And include Manson Supreme and Rockna, as well as the others (danforth, spade, bruce, delta, CRQ, and maybe Fortress). That's your current competition, and the old anchors that people have to be convinced to discard.
Both Chef and I have bought a Mantus (because of the disassembly feature) as a spare/storm anchor, so we basically believe in the product.
This link mentioned by Mantus as basis for the tests he presented:
Claw style (Bruce knockoff), Rocna, Mantus Supreme were compared. As a Bruce owner I was gratified to see that, of the three, Bruce was the top one. In too many of these anchor tests by other anchor manufacturers and by supply houses selling anchors, the tests always show the Bruce being horrible, but lots and lots of people swear by them. Same with Danforths, but they are everywhere. So one can kind of see that if performance were plotted vs. cost, more expensive and newer are always better....no bias here? or maybe a little bit? or even a whole lot, after all, they want us to buy something.
Mantus, many of us believe yours maybe tops, but some additional testing would go a long way in reassuring us.
