Hi Chuck,

The notes mention it's a 3 sail rig. Two mains & a U-shape fore sail. It looks like they're on a batt car type of setup.

A wing sail will work well on a monohull until you want to go off the wind, and then you're right there won't be enough high speed like the skinny hulls to bring the apparent forward .

        Cheers, Russ

That soft wing sail is interesting. A monohull won't exceed hullspeed, so I'm not sure of the application? Maybe they just want to test their ideas regarding their strange mast? How do you reduce sail or put the rig away? Hmmm.

Gary:

If I saw the video correctly, from the force images, etc., the surface areas of the hull at speed are only about a quarter of the whole hull and on the rear quarter where he has a big rudder on each side. If the surface area of the hull approximates a much smaller hull shape, like a dinghy, then the rudder should be enough to hold leeway to a controllable amount………..

It’s the lift that our keels provide and I’m not sure he doesn’t have some step or other shape in the hull under the water that might do the same thing…………….

I’m ready to fill out a APHRF handicap sheet and send it in just to shake it up a bit…………….

So now check out the web site for Formula-marine.com and scroll down to their Omer One Sail…………… ¦ There is an article in the British journal of Yachting Monthly , October 2013 issue that tests this “Wing Sail “ out on an Elan 37……….. . They have a short video with some dramatic views of this rig set up. Lots of good stuff going on out there………….. <http://www.formulamarine.com/projects-2/projects-carbon/omer-wing-sail>http://www.formulamarine.com/projects-2/projects-carbon/omer-wing-sail The rest of their web sdite is also very interesting…¦……….

Best,
