Error on starboard site isonic 131?
 

Are the recommended fin sizes for the Isonic 131 correct?

I just bought an Isonic 133. I am trying to figure out what fins to use with
my 7.8, 9.1 and 9.9 sails. I have 46, 48 and 50 fins. I am 240 pounds. I assume the recommended fins for the 131 would be similar to the older 133. Is that a correct assumption?

Hi,
your finsizes are excellent. You will use 48 and 50 most of the time!
There are no differences in the finsizes in between the 133 and 131.

Ride on,
Chris
