You could have run aground and torn the centreboard cases out, or broken a front beam and pulled a chainplate out along with part of the hull then watch the deck slowly separate from the hull and the rear beam part company from it's mounting block. <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />
So really it was a pretty quite day. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
