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?
