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.

  • 2 x 35 kW IPM engines
  • 77kW lithium NCM batteries
  • 25kW DC generator (real)
  • 17kW AC generator (real this is max 13kW)
  • 9 kts top speed
  • 8 kts on 50 kW, 75 min on batteries or 3.5 h with generator
  • 7 kts on 30 kW, 2h on batteries or as long as there is diesel
  • 6 kts on 22 kW, 3h on batteries
  • 5 kts on 12 kW, 5h on batteries
