I had a similar jamboree during the Perth world cup. Came off mid channel after thundering down a wave. It was probably as a result of fatigue/lack of concentration. The water was big and I found that the straddle method on my V10 was giving me grief so I tried the side saddle method and found it easy. Yes I had to be upwind of the boat but once your arse is in you can sit for a while legs dangling, catch your breath, compose, swing legs over and then head off again.
