That looks pretty darn cool. It looks to me like the little boats just follow you around wherever you go. I'd bet the actual unit you're riding in is so loud and intense, you probably don't feel the thing dragging behind you. I'd also bet that 1/2 hour is probably about 15 minutes too long for most people, based on the capability and maneuverability as demonstrated in the video. Looks to me like you bob up and down for a while, go high, go low, do a few turns, go forward, go backward, and then rinse and repeat. I'd try it for a hundo.
