    I really liked a number of items in the post #31 video.

    This version looks like someone is finally trying to leverage off of the available wing shape for full structural and practical benefits.

    Check it out.

    Catamaran

    I am in discussions with Omer soft wing sails about a catamaran version. I have seen some renderings from Formula France but dont fully understand how it will work on my Cat. Looking forward to seeing Mark IV sail info soon.

    Regards
    Mick

    Gooday bloke. What does one do with all that windage in say - 50 to 70 kts of wind. I've a light weight 40' fast tri. I need 'excessive windage' in strong winds - Cat 3, Cat 4, Cat 5 - - like I need a hole in my leeward float. Nice - but ????

    Ciao, james Looking forward to learning - what you can find out & Thanks a lot for all the info. jj

    Wind age of the bipole do you mean?? From what I am looking at I can't see a quantum difference between the standard mast and a shorter aframe mast. But either way I like the technology and will put my money into it.

    Gooday Mick. There was no intention to be critical - in my question. However I do know that any weight above (let's say 1 to 1 1/2 times high of the width of the hull) the sailing waterline is not helpful at all.

    How do I get in touch with these people??? I have a light weight cruising tri that has a wing mast on it & was looking at getting a more efficient rig. Am wondering if this is the right rig for my vessel??? Weight aloft - or should I say - the lack of weight aloft - is a primary concern of mine.

    Thanks for any assistance. Ciao, james

    Ilan has posted videos on his site. He explains that his wing sail consists of three separate sails, individually hoisted. "When the wing is hoisted, the mast and the wing rotate spontaneously (weather-cocking) into the wind.

    By slightly sheeting in to 00-50 Angle of Attack, off you are..."
