Three visionaries set off to solve one of the biggest environmental challenges of our time: the more than one billion tons of CO2 emitted into the atmosphere each year by freighters. With their ship Tres Hombres, Andreas Lackner, Arjen van der Veen and Jorne Langelaan are already demonstrating how profitable a sailing freighter can be. But their vision for tomorrow goes further: along with the yacht maker Dykstra, they’re developing a high-tech sailing ship that can carry dozens of industrial containers and be navigated by a single crewmember. The key is in innovative software, fed with data the three men have gathered from old captains and the seafarers of bygone times. The three visionaries draw upon the wealth of experience from the past in order to save the world of tomorrow.
