Anchor design is a really tough business...
Of course you CAN steal someone else's design, but if you change ANYTHING, it's not the same anymore.
Anchor design is VERY empirical, and requires a lot of testing and refinement. It's a constant job of "back to the drawing board." Not only for performance testing, but also strength, weight distribution, etc, etc.
Just because it LOOKS kinda like a duck, doesn't make it a duck...
I have trusted my
boat, and quite literally my life, to a
Rocna, and a
Mantus. To a "storm", not so much...
