That was amazing to watch, thank you! i think you're the first person to realise you can pick up the speedboat, and also that it also works when out of the water.. I should really fix that...
I originally had the wake starting directly under the speedboat but it caused problems with it tripping over its own wake, and just bouncing on it all the time, even while stationary. Starting the wave behind the boat was a quick hack to fix that.
