Size of finblade?

[B-J]

I see most monofins now have about the same bladesize. Why is this? Is this the ideal size for freediving? Monofins have traditionally been made for finswimming and I wonder if they have their size from this. Do any of you know if there are regulations in finswimming regarding size?
I can also imagine finswimmers doesn`t want a very big fin when they do their superquick turns, but for freedivers (especially CWT) that`s of no concern for us.
So can it be something with the construction? F.ex: is a wide blade specially prone to V-bend?
If you look at Herbert I think he has a bigger monofin than most.

many makers will make the blade any size you want, Geoffrey from dolphin expeditions has a ww nemo with the biiggest blade I've ever seen, made my tropol look like a kids toy, but he is a huge guy about a foot and a half laller than me with the weight to match, so it looks like a normal fin on him, I think for most of us going much bigger would require allot more effort just to keep the fin stable-- in this case you would probably hope for v-bend just to help with stability, anyway a bigger blade will push more water take more energy I assume so why not just go stiffer if you want more out of the blade I think any major performance changes will be made in an entirely different direction--Dol-fin maybe

if you look closely at the tail of a dolphin, you'll see that he is in the ratio of body weight is very small - but as he swims - flies !!!
Think how to swim little fish with big tails in home aquariums :t:wave

yes indeed, they may look like same a little ! Cause of the leading employee once worked with me and we make fins of the same material ! Comments about our fins and some photos can be seen here : http://forums.deeperblue.com/monofins/86646-starfins-hyper.html,
in my thread !
Wait answers & mail...
cheers

Has anyone else used an "oversized" monofin?

I can see a larger one (and stiffer) being beneficial while hugely negatively buoyant, as well as for maximum power to play around while "breaching"...

I recently acquired such a fin (90cm x 60cm), but have not really used it yet or have enough monofin experience to really make a valid assessment.

As it has a large surface area and is stiff, it does require strong legs / core. It will act as a good "resistance training" fin to build strength as well as working to stretch my ankle ligaments.

I saw a 105 lb woman use a "full sized" monofin at a dyn competition and it looked huge on her, but her performance was great - so surface area might not be such a bad thing.

hello ,

if you look closely at the fin dolphin and evaluate its size relative to body size, you will understand that the size of the glass should not be large. In my finswimming team swim a guy who shows a world record even trainings 50-100im. So it has the smallest fins and the largest muscles of the legs and weighs 105kg and the growth of 185 cm. Large amounts of glass is very hard to push, which entails greater consumption of oxygen!
