Tuttle vs deep tuttle?
 

Can I use tuttle fin instead deep tuttle on iSonic 127 2011. Fin wil be Select elite 41?

Hi zcota,
Yes, the std.Tuttle fin head should fit perfectly in the Deep Tuttle fin box.
The difference between Deep Tuttle and Std. Tuttle is the height of the fin
head (fin root).
You will need longer fin screws as the stock fin screws will be approx.
18 mm too short. So you need fin screws that are about 20 mm longer than what
came with your board.

The Deep Tuttle fin head is recommended to provide more support and structural strength for fins
with a span greater than (>) 55-60 cm. so for a 41 cm the Std. Tuttle fin should be more than
strong enough.
Hope this helps,
Roger

Hi Zcota,

41 look like extremely small for this board, wich sail you use?

All the best
