Welcome to the Mozzie Team! <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
I sail my Mozzie solo and have tipped her over a couple of times. My mast is well sealed and she didn't fully turn turtle. I'm 82 kgs and easily righted her from her side. Don't know about completely upside down. <img src="http://www.catsailor.com/forums/images/graemlins/confused.gif" alt="" />
