The Aerosail maritime vehicle is prepared on March 28, 2015 in Monaco during a test for its planned attempt to sail from Monaco to Calvi, on the French Mediterraean island of Corsica. Aerosail is the result of Stephane Rousson and his partners' ambition to create an innovative, efficient, and silent maritime vehicle, only using the wind as means of propulsion. Its unique principle of flight allows the user to pilot like a sailboat an airship linked by a cable to a stabilized keel, called the Seaglider. The cable acts as the mast and the airship as the sail. AFP PHOTO / VALERY HACHE (Photo credit should read VALERY HACHE/AFP via Getty Images)
