    Seems to me, if a boat (proa) is to be useful and fun, complications detract from those basics. I am about to complete an outrigger, which, as I amended it as construction progressed, became much more than planned and not the simple South Sea rig I had thoughts of building...

    Not trying to denigrate the idea, it is laudable, but just adding a perspective.

    This construction is going to speed and reefing sails.

    Why don't you tell us what you like about this thing.
    The rotary rig has been looked at before and failed then too.

    +1 Mr. Upchurch. I am also curious.

    pogo ingenious dilletante

    Was'n das für'n Scheiss ?

    Looks like an overdesigned, turbocharged and compressorised 2-stroke wankelmotor with flux-compensator on a soapbox-platform.
    Far away from anything.

    Winter sometimes gets us overdesigning...

    The bigger question is why would you add a keel to a proa? The whole point of them is that they don't need ballast.

    Stumble +1. Figured was obvious, but sometimes, as noted, we get to "over-working" project and forget "simple" and consequences. Good point, regardless.

    I have to admit the rotary idea is intriguing, but the devil to pay to make it work. Like my trying to do stayless rig on Hobie 18 hull. Hull itself too weak to do, but what did I know at the time? Now I add stays and simple goes complicated. Stuff happens.

    Real rotary rig was done by Boguslaw Kitowski on a small Catamaran. He has a patent no .: 174934 for it. Masts rolls run on the ring. This provides good conditions for the work of the sail. I would hid this mast into the sail. Should be less air resistance.

    I am slowly getting it. But pics are small, besides both seem to be tackers, not shunters, so I am sort of lost.

    A similar rotary rig was shown in AYRS publications of the 60's or 70's.

    I doubt the patent could be enforced.

    If anyone cared.

    Of course we would have to examine what was actually claimed in the patent. Often it is not obvious nor correctly stated by an enthusiast.

    Crazy as it seems. I keep thinking a shunter is really a full rig version of rotary rig, which seems more advantageous to a tacker, which brings my empty head back to idea of simple is usually best.

    Simple is not always easy to explain.

    Can't tell you how many times have thought, "shoulda found some way to get those Tornado hulls to MN!" And built simple foam outrigger and deal with the mess, instead of what I ended up doing and having to address the complications I did not foresee. Always have to roll with the seas...

    Fun stuff.

    Why make something simple when you can make it complicated?
    Just add water......an open ocean.... ;)
