First ever electric luxury catamaran: Sunreef 50

This boat is generator and noise free at night, even with full air-conditioning and all house loads on! The aim is to run the generator only 2-3 h per day in comparison to 24/7 on similar luxury boats.
Real data shows that we use 2-300 liters per week in charter. Luxury boats with similar size in the same charterfleet doing the same routes, uses 8-900 liters per week. This is simply amazing!
