Which sail with 8.5 and Ultrasonic ?
I have no experience with very big sail and i want a new sail with my Ultrasonic
Actually my biggest sail is Overdrive 8.5.
So I don't know what to choose between an Overdrive 9.7m or an Overdrive 11m !
9.7 may be too small
11m maybe too big
Help, I am lost !
Thank you for any advices .
My weight is 79kg.
