The deck makes full use of the available space - the hulls are even invisible from the stern. Beneath this generous accommodation are two slender hulls optimized to generate a minimum drag between 5 and 15 knots.
Thanks to the combination of a large surface area of solar panels, a 160-kWh battery bank and two 80 kW motors, the 40 should be able to provide unlimited range at speeds of up to 5/6 knots. To keep up with the target cruising speed of 10 knots, the generator will eventually have to be called upon. The manufacturer predicts that this hybrid use will account for only 10% of time under way.
