There's a saying: "Everything that's old is new again."
A couple of years ago someone posted a hand drawing of a wing-like fin that is positioned forward, ~waist-level of the body, and uses the larger muscle groups (quads, gluts) to work it. It's a rather unique concept from the olden days (the '70s) and I'm sure everyone here is always on the look for a way to squeeze out that last bit of efficiency.
I've finally found the patent for it after digging around and am posting it here for the more mechanicallyintrepid amongst us.
Who wants to dive with one? Better yet, who wants to build one??
Enjoy!
