C4 Mono-Flap (progress)

[spaghetti]

I've found this pic of step 2 of the C4 monofin under development. As you will see from the pic below, it's so much different from the first prototype we've discussed about some months ago in this old thread. http://forums.deeperblue.net/monofins/75404-c4-monofin.html
Now step 2 is still a prototype under testing (the guy in the pic is ex world champion Gaspare Battaglia), still with mustang-type footpockets, still 100% carbon.

Interesting!!!! but damn its ugly! but no doubt by the time one is ready for production it will be a good fin, cant say i have ever seen C4 release a bad product so it'll probably work great, but still.....looks only a mother could love.

I'd dearly love to know the reasoning behind that shape (serious quesion, not being facetious. Well, not very). Presumably they studied the physics of the dolphin kick and realised it's not the same as a bifin kick with twice the power. I can't see how a blade that length (even this shorter version) can be tuned to the appropriate amplitude/frequency, maybe Nata can fill us in. Given their materials expertise I'd expect C4 to take the opposite approach and try to build a blade wider and shorter than conventional monos.

i agree Mullins the logic doesnt seem to be there, mind you i could be wrong (wouldnt be the first time) they are good at bifins maybe they are a bit set in there ways as far as design is concerned (hmmm opening myself up for some punishment with that comment)

i'd like to see a wider shorter blade with a rigid front edge and angled foot pockets, not sure on material yet but the fiberglass in my triton fin is perfect for me not overly stiff so mi can cruise with it but when i really put some power into it t progressively loads up unleashing some reall power (kind of like a good fishing rod).

I am not experienced in diving but physics wise the power of ur fins depends on the area u are pushing into the water which will make a drag force proportional to ur area and therefore push u further (if u will compare mono with bi compare the total area of both fins). Other fatcors will affect like the power of ur muscles compared to ur body weight which will make opposite force to the drag force made by the fins. the body shape is a factor more well dynamic body will affect ( this if u compare our body to the fish where fish shape is the most well dynamic body in water) fins made of fiber is less in weight this will give advantage in applying less power to get the same push with other type fins made from other materials. Also we have to take in mind the way of swimming with mono and bi fins where the flow is better in mono where th body will be one piece and easier to flow.
