Re: A question about "One Foot Off" measure

expan....
Fin surface area including shape and thickness is more likely a
better indicator for fin size than merely width of tail 12" OFO.
For your board, fin sizing from 35 to 66cm would apply, depending on
shape and surface area. Thicker fins increase low end planing, so they
can be counted as being bigger in surface area.
The reason you got so many negative responses was that you left out
one very important catagory.....that of wave boards. Typically 34cm
tails at 12" from the tip of the tail, they almost exclusively use fins
22cm long for big guys, around 20cm's for guys my size (146lbs.)
Current fashion on freestyle boards is about a 18cm fin used on a
tail width around 40cms, and it works, for them.
