    Hello,

    During the summer of 2020, I developed a new type of wing sail. I was thinking about a new type of sail that would be ideal for a cruiser ever since I bought my boat, in 2016.

    I made a small trial sail as a prototype. The major obstacle was testing the rig, as I do not have a sailing dinghy, and there are few sailboats around where I am based (eastern Romania).

    Check out the Instructable, if you want full details on this rig.

    Wing’soul. Easiest to Build Wing Sail. https://www.instructables.com/Wingsoul-Easiest-to-Build-Wing-Sail/

    * Wing sail that requires NO rotating mast
    * No articulating hinge for camber control or tacking
    * Flat cut mainsail and jib; a first timer can tackle the sailmaking
    * Reduced mast turbulence; better slot effect
    * Has all the great properties of a junk rig: docile handling, sea worthy, easy to reef, great twist control, no sail flogging, no sheeting winches, easy downwind sailing, auto-tacking, easy to jerry rig if it rips (by lashing battens together), easy and cheap to repair because parts are general (not marine/sailboat specific), sail canvas can be UV-resistant, one working sail (no need for a sail wardrobe)

    That is a very interesting design. I assume, for larger vessel applications, some cutout can be made to accommodate spreaders.

    I would love to see pictures of it in action.

    Your sail looks similar to Paul McKay's Aerojunk rig. He posts on the Junk Rig Association Website. Maybe you can collaborate with him.

    ETA:
    After reading your Instructable I see that you are very aware of Paul McKay and his Aerojunk. My bad! :( Would like to see how your sail works on a boat, as I'm sure you would too.
