I hear what you are saying, but seems to me you're re-inventing the wheel. Why would I want to hook up a small gas engine to an AC compressor when a small generator will run the AC unit as well as any other 110v appliance(s) I have on my boat. I can even take it home with me to use as a back up generator for those instances I lose power.
Not saying it is a bad idea, but if it was a good idea, someone would have developed one by now.
