Let it be a cautionary tale.
The thing about power boats is, just because they can go very fast, that doesn’t mean conditions are favorable for such speeds. Also, having a lot of money doesn’t magically grant you the ability to actually control the vehicles that you’re fortunate enough to be able to afford. We see the same thing with supercars all of the time. The following video shows what happens when you drive your boat entirely too fast, people get hurt.
Five of the seven people in this boat were taken to the hospital following this crash, mostly for broken bones. As for the driver- whose face got better acquainted with the boat's floor- he was fined.
