Freedomfins

[Erik]

The news from DEMA about Freedomfins is interesting. They are on to something I believe http://www.freedomfins.com/index.html
A few years back, I was struck with the idea that a whale's tail fin is full of the bones that we would call leg, feet and toe bones. This, combined with their muscles in the fin, allow the animal to manipulate the fin throughout the kick cycle. We obviously can't do that, but my thought was that a monofin should be strapped on at the knee, not the feet, thereby accessing stronger muscles.
If the designer comes up with a monofin, I think it would be incredible.
If the designer comes up with a more powerful (than at the moment) bi-fin, it would be a good spearo tool. The present small-ish set of bi-fins looks too small to me, given the quick movement of the diver's legs in the video.
Just my thoughts.
Peace,

Very interesting idea. I watched the video and it looks like potential, but it's not there yet. I think Erics right, blades too small. The video looked like a race between the freedom fins and what I think were split fins. No surprise the freedom fins were faster, but they look pretty inefficient and centainly slower than long fins. I'm wondering about maneuverability, especially with bigger blades.

I agree - they look more for scuba where you need a lower gear.
