This post is rather late but after about 2-3 hours of sailing on my Carve 121 it developed a hairline crack on the flat bottom of the board

.
I took it back to
Bigwinds in Hood River USA and they promptly told me to pick out another board

.
I did not like the feel for the Carve 121 so I got a Starboard KODE 113
which I love, nice and loose
.I would buy another board at Bigwinds in a heart beat, great place with friendly people.
Just a reminder for everyone if you can test ride your new board first before you buy.
It worked out well for me but that was all because of the flaw in the board.
