I slipped off Karl's hull with my "fancy" (read: 11 year old) surf booties while righting it at Hirams, and bounced off the lower daggarboard and it didn't break. I'm 6'1" and 185 lbs. More of a glancing blow to the daggar than a full on "cannon ball" type hit, but nonetheless...

Both Karl & my first thought was "s!" I hopre I didn't break something!
