I saw a TV show filmed at North Sails showing how they make one of those A
Cup mainsails. They form a solid plug of wood, or similar, then lay laser
pre-cut pieces of kevlar, etc on the plug and sew it together with a giant
moving sewing needle on a CNC controlled machine in 3D.
The amazing thing to me is how close they can haul the sail in and not
stall it. They call the "foils". Go DC!
