Dear All

I am litlle confuse. Recomendation in tehn. spec for isonic 127 for fin is next:
7,5m2-10m2 sail recomendation is fin 38-50cm.
On board I have recomendation for fin 44-52 cm.

For severne overdrive 7,5m2 I do not know if fin 41 (select ) ok ?

Mislim da će ti biti premala, osim ako nije apsolutni flat i potpuni downwind, mislim da će ti trebati nekih 44cm (In my opinion a 41 fin will be too small, unless it is absolute flatwater and downwind sailing ... try some 44)

Hi Marko,
Thanks for your answer here.
Suppose you could translate it into English so the rest of us on this forum (those who do not
speak or read the Croation language) could benefit from your advice?

Hi GG,
the 7,5 will work ok with a fin around 45 - 46 cm on your iSonic 127 out of my view. It´s a wide board with a wide tail, which needs a longer fin. It doesn´t matter how small the sailsize gets. I just would go on a really short fin on the 127, if I would use the board for teaching intermediates or if the water water would be extremely shallow.

What´s your sailing level?

Cheers and hope it helps,
