An Electric Solar & Sail-Powered Catamaran — The MODX 70 - CleanTechnica

The MODX 70 is a fully electric catamaran that distinguishes itself from many so-called "eco" vessels, which often rely on diesel engines and hybrid systems despite marketing themselves as environmentally friendly. Unlike these hybrids, the MODX 70 operates solely on electric power combined with sail propulsion, eliminating the use of fossil fuels. It features 70m² of advanced NME3 solar panels capable of generating up to 15 kWp, covering about 35% of its energy needs, and a 250 kWh lithium iron phosphate (LFP) battery bank for safe, long-lasting energy storage. The vessel is powered by four electric motors delivering a total of 40 kW and can cruise 110 nautical miles at 5 knots on battery power alone. When sailing with adequate sunlight and battery storage, its range is effectively unlimited, with speeds varying from approximately 10 to 18 knots depending on wind conditions. Additionally, the MODX 70 includes a variable-pitch propeller system
