He didn't sink it! LOL. There is a video showing this boat spinning on its axis, but this was his first time and he didn't realize how fast this boat picks up speed, even at minimum throttle. These boats are weigh sensitive, and another video shows 4 people onboard running flat and even. This is not a boat for open water, it's designed for rivers and an occasional boat wake, not wind driven waves. See expandacraft.com for other boats and outrigger kits.
