ISonic 117 (2011) Fin question for Remi
The 117 is deep Tuttle. Is there any problem, potential dommages or speed lost if I use Tuttle fins instead? What are the inconvenience, if any?
Also, in previous thread, the fin charts says 44 cm Deboichet R16 fin for 7.5m sail, what would you suggest about the fin stiffness? As I see on the Deboichet web site there's stifness option we could choose from as well as the Rake angle, what would you suggest?
I am 170 lbs or 77 kg.
Thanks a lot!
