Split fins?

And kayak paddles, or the blades on boat propellors?

If you look there is a split between the blades in the propeller isn't it? You don't see a single blade propellers too often do you?

Do you have ANY physical evidence to support this opinion or do you just plan to string together as many unrelated anecdotal comparisons you can think of?

The plural of anecdotal is still not data.

Neither side of this issue has provided nothing more than anecdotal data and personal opinion. The value of which is determined solely by the wearer.

So statistically insignificant findings with no control setting... They didn't even use the same test subject for all of the fins!

I honestly don't even care about the fin debate, pseudo-science just gets under my skin.

Well considering that water and air are both fluids the same principle applies of channeling/moving fluids around.

I'm well aware of that.

Turbochargers compress air, and still have no more or less to do with the discussion. Fins aren't airplanes and they don't work like them.

edit: my bad, I suppose you're thinking about the flapping phase (eagle), not the gliding phase. I get tired of comparisons between airplanes and fins, hence my tendency to reply without really thinking it through. FWIW, I believe the eagle's wingtips have to do with allowing them to fly quietly, not with lift in general.

Ding! We have a winner! I agree completely. No matter how many people berate people who own an opposite view, they still just rely on their opinion and conjecture.

Looking forward to you providing scientific data.

These are the fins I use, I find that I can get 15 PSI to the furlong improvement with these fins over any other fin out there. They have the awesomeness of paddles, with multiple splits to be even MORE efficient than a lowly single split.

One of these days I hope to stop worrying about fins and just enjoy diving.

Ignorance is curable, willful ignorance is not.

iztok... dude! he photo shopped the fin.... He's joking



too funny..... (now I just wonder if that's curable ignorance, or willful ignorance? )

Wow,
I have no response to that. You are correct, I don't think there
Are any single bladed props out there.
