These guys must be in a race because sensible people in a hurry don't sail.
In a jibe, especially an unexpected one caused by a wind shift or quirky swell, there is almost no bite to the rudder and you tend to roll right over. This was always my least favorite part of the race and I only did it with wooden spars for a couple of years. Winging out the foresail was just asking for it.
My father has a great picture of his Rhodes 19 during the Nationals where they put their spinnaker up sideways. They still did very well which surprised one and all. It was, naturally, the picture the press published.
