A complete marine propulsion provider for electric and hybrid vessels

With us you get all out of one hand: in-house lithium-ion batteries, DC-generators and shaft or Z / Jet drives and it’s  all controlled by our own thruster control and EMS / PMS software systems. 

As long-time sailors and boat owners we are aware of the problems that can occur on a daily basis.  

Hence, we design backup-ready systems with simplicity in mind.

For big systems with parallel strings we have double communication lines and double system controllers with back up functions.

You will be guided through the process of turning dreams into practical hybrid and electric vessels using top-notch, cost-effective quality.

The first luxury electric catamaran: 

Sunreef 50

Real data shows that we use 2-300 litres per week in charter.

Luxury boats with similar size in the same charter fleet doing the same routes, uses 8-900 litres per week.

Tiril 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.

The catamarans can be equipped with advanced electric propulsion allowing power to be generated from the propeller rotation while the yacht is navigating under sail. This energy can be used to power the propulsion battery bank as well as the electronics on board.

  • 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
