    Are there any examples of this idea for a mototsailor? Actually 3 sails; one mast on each side with big square sail in the middle and triangular sails on opposite sides.

    More inline with jury get home sail, riding sail, sail assist, lower CE, possibly masts small enough to be setup/takedown by two people, etc., etc.

    Too much weight, because a compression strut would have to be put between the two masts to make conventional staying work. this compression post would have to be thick enough not to bow under compression, without any spreaders.
    With carbon fiber unstayed, masts this arrangement might work, but even then, with a monohull, the two mains would be too close together to provide their maximum drive potential. Could end up providing as little as 20% more drive than a single main.

    Sounds like a fisherman or gollywobbler

    Raises center of effort.

    The fixed longitudinal head of sail makes it very difficult to realize drive outside of extremely narrow wind angle.

    As you see no competition strut nessicary

    What i'd seen had two masts with stay wire between, triangular shape, luff horizontal at top with clew hanging down. Will try to get a pic.
