Sail Magazine has an article on wing sails this month featuring Beneteau's new experimental boat:

  There's not much new information, but they do show the Beneteau sail in detail, and also mention that it was inspired by the Matin Bleu sails.  They have a nice view up the center of the sail as well as a full sail photo/diagram.

  It's inspiring to see such a large mainstream manufacturer sign on to the concept, and comforting that they've chosen a reef-able design.  It's a simple design that doesn't require multiple panels and a hydraulic camber adjuster.

  There are also links to a few manufacturers, including Advanced Wing Systems ( http://www.advancedwingsystems.com ) in Australia.  SoftWing in Switzerland ( http://soft-wing.ch/en/ ) is mentioned with a photo, but no links or web addresses are given.

  I'm still a fan of the SoftWing sail, partially because it doesn't require a rotating mast, and partially because making the lead foil section out of three hinged pieces really creates a nice shape.

  However, I'm not sure the fixed mast would work as well on a proa where you might easily have 180 degrees of swing on the sail.  It might be a challenge to set up the halyard and lazy jacks for that.  There's also something to be sail about the simplicity of /not/ building the lead section out of multiple hinged pieces. 

  Perhaps there's no way to avoid a rotating mast.
