It's funny, the jet boats, the contemporary ones mentioned above, just never caught on out on my lake. There is I believe one on the lake and happens to be the 24 foot class. Even Chaparral has been making them for a few years using the Sea Doo engines but no takers around me. I have a supercharged waverunner and is the funnest thing I own, it gets 90% of the use and the rest of our boats just sit. It drinks gas so badly that I keep waiting for the global warming police to show up at my door which I assume will be Canadians when they do finally find me. I can't imagine a full size boat that has a less powerful engine than my waverunner or worse twins whether they be supercharged or not....I'd have to be filling it up daily with half a dozen cans of gas on my dock. I can't stress enough how much gas an 850lb supercharged waverunner uses and so a full size bowrider I imagine would be even worse if that is even possible. As for the whole shallow water thing, you can putter over shallow water but you will vacuum up the bottom if you take off from the shallows. Yamaha has sort of corrected their slow speed steering issues but generally as mentioned, you have to make your move ahead of time for the boat to react how you want at the point you need.
The jet boats do seem to depreciate faster. To me a jet boat would be a novelty or a great third or fourth boat on a lift in front of your place after the pontoon, wakeboat and fishing boat.
