Pioneering Electric Luxury 2018
EPTechnologies first fully electric luxury catamaran.
Showcasing silent performance and advanced energy management
2018
The first luxury electric catamaran:Sunreef 50
Efficient Fuel Usage: Real data shows a consumption of just 200–300 liters per week during charters.
Comparison to Peers: Similar-sized luxury boats in the same charter fleet on identical routes use 800–900 liters per week
Tiril operates completely generator and noise-free at night, even with full air conditioning and all house loads running.
The goal is to reduce generator usage to just 2–3 hours per day, a significant improvement compared to the 24/7 operation common on similar luxury boats.
The catamarans feature advanced electric propulsion that generates power from propeller rotation while sailing, supplying energy to the propulsion battery bank and onboard electronics.
