Many years ago I had my 16ft Condor totally destroyed (broken mast, boom, torn sails, broken battens, holed hull) by an inexperienced RIB driver who tried the method described BUT didn't shut the power off as the boat came up. So instead he accelerated away (the RIB had at least 55Hp on the back) and proceeded to flip the boat back over, fully turtled in shallow water at what seemed like zillions of knots.

Needless to say, nowadays I will only VERY GRUDGINGLY accept help from a rescue boat if it is a case of last resort....
