Isonic 144 supplied fin with tuttle box.
 

Hello. I bought an Isonic 144 board, the board comes with a Drake Slalom R13 Race NR 520. I noticed that the box on this fin is tuttle and not deep tuttle. Is this the right fin for the isonic 144? Any issues with performance/torsion with using a tuttle fin in a deep tuttle box? Thanks for your help.

The fin that came with my iS144 is tuttle. No issues, feels solid. If you go with a bigger/powerfull fin then deep tuttle only.

Can only confirm...the long bolts are fine and the fin works good (considering it is a Drake stock fin) as well.
Enjoy the board!

Ciao Michal.
