It's a pretty low powered jetski, only 7 hp. It's a neat set up but I have seen and have ever confidence in the public's ability to abuse the privilege associated with the ownership and use of such a machine. The popularity of ATV from dirt bikes, to 4 wheelers to 4 wheel drive pickups has practically eliminated access to private land in the Southeast USA, I suspect the rest of the country has seen similar damage to land owners and the withdrawal of access.

Besides, most of us need the exercise of paddling, rowing or some how manually propelling our craft.
