Generator
If this is a 25.5, it would be pretty noisy running any engine for a long period time. Frankly would drive me nuts. I invested in a really good deep cycle wet cell battery and charge it with a electronic multi-stage (charge, equilizaton and float) charger. I check the cells with a hygrometer on a regular basis. If you need AC power for computer or other devices. I would do two quality batteries and a inverter. Using a strategy of engine running and solar maintenance or electric charging to keep the batteries charged. This would maybe be more efficient than running an engine continuosly just to operate a device. Unless your doing refrigeration or Air conditioning.....Refigeration - Get a thermoelectric cooler from Igloo, Air Conditioning - Go sailing, get in the shade, use fans, jump in the water....or go home... Frankly learning how to cope with as little AC is probably better in the long run....is'nt that what owning a small boat is about? Self relienace, creativity...don't give up on DC....look into solar and wind generators....Rutland make an affordable small boat wind generator and there are lots of great choices in batteries and solar panels out there....
