Had it happen to me last summer.
We were ripping along on a screaming reach, two guys on the trapeze, and me on the tramp driving (in between drinks of water!). I stuffed it hard and blew the main sheet, "center" guy on the wire had the jib sheet, and tried frantically to release it to no avail. Imagine all three of us still poised and hanging in our positions anticipating a recovery, but slowly rolling forward in a cross between a pitchpole and capsize. When it was obvious we were beyond the point of no return, there was no where for "center" guy to go. He fell straight into the mast about two feet up from the base, and the mast "popped" out of the base.
Have never seen that happen before and hope to never experience it again. From this point, turtled boat with mast not attached, it was a pain in the a$$ to get everyhting sorted and towed back home all the way across the lake (turtled boats don't tow well at all). No damage to base or step, in fact only damage was to the sails during the tow. Damn these Hobies are tough!
