This is the first I have heard of these Thundercat racing boats. Apparently it has been going on for quite some time though. If only I knew when I was younger I would have been racing these things. Still might.
These Thundercat racing boats, not to be confused with the Thundercats cartoon, are a class of inflatable boats strapped with a 40-60 HP motor. These boats are lightweight and have an amazing power to weight ratio. The Thundercat races have plenty of airborne boats and crashes. Simply amazing, videos after the break.
