Spain’s Bound4blue has installed what it says are the biggest-ever suction sails on a Dutch cargo ship.
The 17-metre eSAILs have been retrofitted on an Amasus Shipping multipurpose, the 2,850-dwt Eems Traveller (built 2000).
The Barcelona-based company said the system is based on the use of a thick aerodynamic profile and smart suction to increase the propulsive efficiency, resulting in a system that produces seven times more lift than an airplane wing.
