Behind GR are the initials of Gilles Reigner, the owner of Catathai - who wants to validate a second brand that is both green and high-end. With a doctorate in physics, this Frenchman living in Thailand is well placed to manage a 100% electric powercat project whose energy production is ensured by wind generators and solar panels.
The GR60 guarantees a cruising speed of 7 knots and a top speed of 18 knots thanks to a pretty wide range of technical solutions - fuel cells (4 x 5 kWh), high efficiency wind generators (2 x 10 kWh), a large surface area of solar panels (totaling 15 kWh), powerful electric motors and, of course, a large battery bank (between 100 and 200 kWh). The design of this powercat calls for a careful lightweight sandwich construction associated with very fine hulls and optimized aerodynamics. The interior layout and the deck plan are customizable according to the wishes of the owner.
