House batteries: Four Trojan T105 batteries (two banks of two six volt golf carts)
I have them to a battery switch (for maintenance charging etc) but I never have removed them from Both.
Engine starts on a single Trojan battery
 

Four Siemens 75 watt solar panels (flat mounted on top of arch)  I added two more 80 watt panels in Tuvalu to keep up with the refrigerator demand in the tropics (we typically use 60 Amp Hours just during the 12 hours of night).
 

Rutland 913 wind charger (nice and quiet)
 

Two NC-25 charge controller (one for solar one for wind)
Use 12 volt hot water heater element as divert load (Do NOT hook to existing thermostat wiring)
Each charge controller can be switched to charge either the engine or the main bank
 

Balmar 75 amp Alternator to charge splitter and ignition noise reducer. Also have a blower fan (with ducting to the cooler section of the boat) to blow air at the back of the alternator to keep it cool.
 

Home made towing generator. Bought an old Amatek permanent magnetic 32V tapedrive motor. Inserted a diode in the line to prevent the batteries from turning the motor. I hook up a spare towing generator prop (from Downwind Marine in San Diego) and throw it over. This roughly keeps up with the autopilot and lights during the night (3 amps).
