GT D – Reliable but not green
2 Diesel engines from 80 to 480hp. Diesel engine is mostly used on power catamarans with proven reliability. With engines over 150hp fuel consuming is high and we recommend other versions such as FOIL version that is Diesel with much better energy saving (about 40% at cruising speed 17kts)
GT S – Smart Hybride + Solar
1 Diesel engines from 80 to 150hp / 1 Electric engine 40kw.
That was tested on hull #1 ; results are excellent. We really like this version that is very simple with 48V Lithium park.

GT E – Full electric engines + Solar
2 Electric engines from 2 x 40/280kw. Of course you need 1 strong diesel engine used as DC Generator 50/120kW for security and long distances. Lithium park is over 400V (except for 2x40kW engines)
Foil – Pass the 30kts limit
This version is today based on Diesel engines but soon we will propose Electric solutions. You may request your target speed and therefore size engines : Cruising speed 15kts / Max Speed 23kts or Cruising speed 17kts / Max Speed over 35kts.
Only 13T light Displacement …
The key point with Power catamaran and especially electric configuration is Weight. With 13T light and 16T ready to cruise with many options, you clearly have one of the lightest 63ft Power Catamaran. We need very few kW energy to achieve -30% of hull speed (13.5kt). Cruising 9kts with 1L/Mile coming either from Diesel to propeller or Diesel to DC generator is already achieved.
Compared with 30T light displacement catamarans you need 35% to 80% less energy (kW) for same speed.
Use Solar to Power …
GT S and GT E versions have electric engine(s) and massively use Solar panels to load Lithium park energy. This energy is stored to be used when needed. As real, if you intend to use ONLY SOLAR energy to power the Class 6 without using lithium park ; you need to target max 6kts with beautiful sunny day from 11h AM to 3h PM. Then you will use lithium park energy.
Use Kite to Power …
You have many Kite solutions to chose from. They can be super easy to launch/get back such as LibertyKite. You expect 5kts speed with 20kts wind with the small 20m2 kite. A 40m2 kite will be tested soon. Other brand and solutions are available but expensive and more complexe … to be tested.

Class 6 Power is configured with optional Flybridge.
That is a custom area with different layout solutions.
Final design upon your requirements.
Class 6 Power Foil is made to go really fast (over 35kts) . Two options : First one with normal Diesel engines and conventional shafts. The purpose is to give lift with foils and save fuel. Second one with electric engines and special foils stern to completely FLY and pass the 35kts.
