Fin for iSonic 137 for non-overpowered conditions
I bought an iSonic 137 which I will match with an 8,7 free-race 2 cam sail for light wind.
I am 1,78 m height and weight about 74 kg.
According to the chart on the back side of the board, I should get a 48-49 cm fin.
QUESTION : Does this chart apply both for overpowered and non-overpowered conditions?
If not, what size of fin should I use for non-overpowered conditions?
Thanks very much
