looking at the infinity branded otter tail,
cute design, but will it work?
wil be used more for surf SUP than distance/race
shakas!
I made a paddle with a blade that shape once and it was very soft going into the water and the power increased as the blade got deeper unlike most paddles these days that have a more triangle shape blade that gives a big bite as soon as it enters the water.. It felt a bit weak but the long narrow blade lets you half dip or fully dip depending on how much power you want.. Buy one and let us know how it goes..

Here is a bit of a discussion on the Otter tail with Jim Hayes from Tropical Blends Hawaii. He is a big fan of this paddle and was paddling a wooden one last time was there.
Hey AA.. What were those dimensions again?.. 
" Dimensions: 6″ Wide by 26″ Long"
Scotty Mac was using one a couple of years ago at the 09 Mambo.
The blades are pretty flexy and the shafts are stiff and a bit too fat for my liking.. also a bit heavy.
That new carbon one looks interesting.

Here's my opinion on the theory / my theory (note - I have not used an Otter Tail Paddle).
Thin Width - should help assist in keeping the shaft vertical, and keep the paddle closer to the centre line of the board....
Long Blade Height - I would think it would take a fraction longer to sink the full length into the water, on "the catch", and ditto on the exit. Therefore each stroke could take a "pouf-teenth" (a fraction of a second ) longer. Which is actually a bad thing.... So I can't see this being good for racing...
Blade Flex - you would expect some blade flex....
Note: I have a Tropical Blends Paddle that is about 16 months old. Came with a board. The particular paddle that I have, seems to have a cheap shaft, with plenty of flex. Good for the shoulders, but not good for power.... excessive flex loses too much power.
