The instant invention describes devices and methods of measuring the differential air pressure at numerous representative points across the surface of the sail and providing visual feedback of areas of ideal laminar flow and areas of less than optimal airflow with an indication of how the sail must be adjusted to create the maximal differential in airflow. The invention utilizes an array of sensors that detect minute variations in barometric pressure and other data on each side of the sail surface. These sensors are connected together to form a network or net across the sail. This connection can be physical, using wires, or it may be wireless, using for example, but certainly not being limited to, Bluetooth LE 5.0 or other wireless topologies or technologies. Finally it may utilize a combination of wired and wireless connections to fit individual situations and may couple with existing terrestrial and satellite ship networks.

One embodiment of a deployable reversible camber sail system, based on a deployable shell (58) contained within a mast-sail assembly (11, 12) and supported and controlled by additional assemblies (13-15), is disclosed. The embodiment may be easily and quickly configured into the furled, feathered, port tack and starboard tack sail forms. In addition, this embodiment represents a highly efficient sail module which may be controlled by a single human operator or automated computer-based control system. Additional embodiments, utilizing assemblages of the first embodiment sail system module, are described.

A sail comprising a rotating flexible mast sleeve wrap surrounding the mast and attached to a sail track for controlling the movement of the sail. The sleeve assembly is slotted to allow for partial rotation of the sleeve wrap, the sail track and the sail, so that the sleeve wrap, the sail track and the sail rotate to form an aerodynamic shape on the lee side of the rotating flexible mast reducing aerodynamic losses.
