Setting and penetrating are quite different things Marin. One is dependent on the other of course.

The issue of convex vs. concave is purely physics or geometry or whatever science it is. A concave survace concentrates material--- be it mud, air, or dirt in a ditch-- by forcing it toward the center of the suface. In the case of an anchor, a concave fluke surface will concentrate the bottom material toward the center of the fluke, which will increase the fluke's resistance to the direction of pull. It's why the concave surface of a shovel picks up and holds more dirt than the convex side.
A convex surface sheds material.
Peter-- The quote I included in my post was from Djbangi in his post 501, not psneeld.
Sorry I cannot deliver you free anchors, if I did you would have to ban psneeld, seems all too difficult to some so we will carry on regardless supplying anchors direct at your distributors cost to offset freight, it may seem odd to operate this way, then again customers are so passionate about anchor technology there seems to be no length with some as to how far they are prepared to go, then again the landed cost with our discount works out pretty good for most.Regards Rex.

Yes.One thing occurs to me that I have not heard considered, but I may have missed it here or in a different thread.
It seems reasonable that the deeper the anchor gets, the more compact the substrate will be, and therefor the better the holding. Between a concave and convex shape, might the convex shape while being set and shedding material, be able to dig deeper? Could that be an advantage?
Considering the lamentable Aussie costs of production and shipping distances I`m amazed Muir markets competitively in USA, they have trouble doing it here. But they are quality,they provide back up service, and within reason, quality & reliability can beat price. My Muir Cheetah (with its new 1200w motor) and my Super Sarca get along fine.Rex, I wish I was in a position to be your US distributor. I think your anchors would sell.
I think it would be a no brainer for Imtra Corporation. They already import Muir Windlasses from Oz, have the warehouse facilities and are already established as a distributor in the USA.

If the roll bar contributed to setting, after the anchor......What a load of rubbish some people suggest
My best guess is that the recent growing trend in anchor purchases moving toward New-Gen spade types has alarmed the people at Fortress and any close look at boating magazines regarding what's on the bows of boats will confirm that trend. Look at what's on my bow. It is not perfect but it has so far shown itself to be an all around good performer even in soft mud.
