MODX 70 - A 100% electric catamaran featuring a twin rig and wide sails

Create a notification for "Catamaran"

To achieve this feat without jeopardizing safety, the MODX 70 designers decided to launch a catamaran large enough to support a very powerful battery bank while increasing the potential area of the solar panels - it stretches to 750 square feet (70 m²). The two motors are capable of a 100-mile range. The fully automated rig is perhaps the most amazing feature as the two retractable carbon masts - one on each hull - each support a 1,345 sq ft (125 m²) inflatable wing. These two wings ensure a 35% better performance compared to a conventional rig with the same sail area. The principle of this catamaran is to reach 10 knots very easily to ensure efficient hydrogeneration (thanks to the variable pitch propellers) of about 3 kWp. Hull #1 is already in build, using 38% biosourced epoxy resin, 40% recycled PET foam, flax fiber and cork. Launch is scheduled for the start of next summer.
