Another is its ability to obtain energy for recharging the batteries from multiple inputs, especially renewable sources:
1- Regeneration from wind power - when the propeller turns in the wake under sail, the drive motor automatically becomes a generator and sends electricity back to the batteries.
2- Solar cells and wind turbogenerators - If the boat has space available, twelve 12 volt solar panels can recharge the 144 VDC main battery pack, while a wind turbine tops up the house batteries.
3- Dockside plugin - standard AC power is fed into the battery pack through a battery charger.
4- Backup diesel generator - produces direct current at 144 volts to charge the batteries directly.

The battery pack delivers 144 VDC to:
2 - a DC-DC converter that provides 12 VDC or other low voltages to the house power system
3 - a DC-AC inverter that provides 110/220 VAC to AC appliances.
This central source of power results in substantial reductions in diesel fuel, noise, fumes, routine maintenance and repairs.

The original 10 ton cat came with twin 27 hp diesel engines. These were replaced with two nine kw electric motors, which turn bigger props than the original diesels.
The boat is equipped with 12 rooftop 12 volt solar panels, which directly recharge the main 144 VDC battery pack.
