The first time we capsized our Hobie 18 the wind was only 5 mph. We were slowly on our way out to the race course and not really paying attention to anything and our sheets were cleated, because the wind was so light. Well, a little puff of wind came along from a different direction, and over we went. Then, of course, it was back to 5 mph, and it was extremely difficult for the two of us to right the boat. At that time we were sailing at minimum crew weight of 285 lbs. And we were both very experienced catamaran sailors (or so we thought <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" />).
