A Zero-Fuel, Ultra-Green Boat
The First 100% Solar-Powered Boat Approved for Passenger Carrying in U.S. History
The Solaris/Solar Sal 44 not only uses no fuel, but she is designed to have the lowest carbon footprint possible-to be as green as possible. Of course, using no fuel at all is already super green and super low carbon, but the hull is also built of wood-of wood-epoxy/strip-plank sheathed with glass. (Wood-epoxy/strip-plank construction sheathed in glass has maintenance and longevity characteristics equal to that of conventional fiberglass.) This means that 95 percent of the hull structure is from the renewable and low-carbon material wood. Other boatbuilding materials-fiberglass, aluminum, steel and even ferrocement-have much, much higher carbon footprints.
