Cal, that strikes my as one of the more profound posts I've read in quite a while. Pete said he'll do whatever to keep Lesman in an Epic, and I'll go on record saying I'll do what I can to keep you in your beautiful white/black X22. Seattle Epics, represent!
10 to 12 gph, that's just sick.
If I were to pick one boat right now I'd take if my S22 burned/sank/got buried in a mudslide, it'd probably be the SAN, simply because it's pretty high quality, a little racey, and throws a really fun wake. Downside (besides price) is the small cockpit.
Above all, I'd love to buy a blank hull and fit my own engine into it. It'd just happen to be a intercooled, supercharged Toyota 1UZ.
If I really wanted to get crazy, I'd look into a hybrid setup where you have batteries or caps that augment a small gas engine while getting on plane. Basically, think of a little 2 liter VVT-i 4-cylinder that peaks at like 140 hp. The prop is turned by a motor, and the motor is powered by batteries and/or caps. The batteries are charged by the gas engine. You let the engine idle until the batteries are charged enough for the hole shot, then you gun it. By the time you get up on plane, they're pretty well depleted. However, the little four-banger delivers plenty of power for cruise and is also able to deliver a little excess to recharge the battery bank. Once the battery's recharged, the engine throttles back and you cruise around at some ungodly low fuel burn. Rider falls, the cycle repeats. Worst case, your rider falls while getting up and you've got to wait a little bit for the system to recharge. That all assumes a heavily-ballasted hull, cuz I'm pretty sure that a good 4-cylinder would easily get one of our boats on plane empty without any help from the batteries.
And a wet hull. With wet gunnels. And snap-in carpet. And integrated Windows Media Player, DVD player, GPS, and optically-guided tower-mounted DV cam that serves as rear-view mirror AND ride recorder.
