ship type

The turbosail or French '''''' is a marine propulsion system using a sail-like vertical surface and a powered boundary layer control system to improve lift across a wide angle of attack. This allows the sail to power the boat in any direction simply by moving a single flap at the back of the sail, unlike conventional sails which have to be continually adjusted to react to changes in the relative wind.

SolidSail, sometimes referred to as Solid Sail or SolidSail Mast Factory (SMAF) in reference to the eponymous subsidiary, is a wind propulsion technology designed for large vessels, developed by Chantiers de l'Atlantique in Saint-Nazaire, France. This innovative system is based on rigid sails made of composite materials and a tilting gaff rigging, enabling hybrid or primary wind propulsion for commercial and cruise ships. It is also the name of the subsidiary created by Chantiers de l'Atlantique in 2023.
