If even the inflatable jet ski-like device is too scary, or too big, maybe what you need is a simulator such as this one from firstSTREET.

Yes, the jet ski is inflatable, but it can't be used as a real jet ski. It's part of a video game! It's a pity this device has a weight limit of 110 pounds. The idea of a home jet ski simulator sounds like a heck of a lot of fun. Where's the adult-sized version?
