In my famliy we had 3 2006 starboards, together with my friends we used 5 starboards from 2006 with tuttlebox. models:
On 4 starboardswe saw several cracks around the finbox. But we never did repair it. I only made it flat, so I wouldn't have any rough surface in scoop/rockerline. A very proffesional boardrepair
shop in the Netherlands told us that the Hard-foam used around the finbox is waterproof, so repairs would be expensive & unnessecary.
On another board a JP freerace
we experienced with a select fin RS7
, which was like 10 times more powerful than the standardfin (eventhough the select was 5cm shorter!?!
)that complete finbox
including hardfoam seperated from the boardcore
. After that we heard everytime
when sailing that hit a gust a CRACK #!$3^&*(*&%
^, That finbox was completely replaced by a new tuttlebox.
