Parafoil Sail

Description

First draft to figure out Array and Mirror modifiers to generate a mast which is hidden between two sails. To change the curvature the sail can be wound into a serpentine. The sail needs to be airtight and is pumped up by inlets in the leading edges with valves. I would really like to change pressure with wind speed and thus with height. This seems to be difficult. Symmetry and weight makes this most suitable for automated mono hull cruiser ships. Before that: TODO: rigging and cloth simulation
