I have been looking at some older (limited fixeruppers) 24 to 26 foot pocket cruisers. Air conditioning is an absolute - either for just a short escape from the heat or to spend the night. I have found many with A/C but very few with generator. All are set up to run on 'shore power' which I will not have. The boat will be kept on a trailer. Is there a way to run A/C without a generator, either using a small portable generator (I am aware of CO poisoning issues) or through adding a bunch of batteries or is there a way to permanently mount a generator similar to how such equipped boats come from the factory?
