The session that killed my RRD 268...I hit stone at approx 20 knots, not to hard since the fin had only minor scratches. I guess the reason was the "crushed" deck just in front of the backstraps had significantly weakened the board....Luckily my brother has an identical board that i can borrow if needed:). Wind was good but a little stronger gusts would have been good, i felt there was more to give from this board/sail combo...
