Re: Stus-List Flying lead keel + New Wing sail for monohulls ala AC72.

[Russ & Melody]

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 .

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………..
/p>
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…………..

The rest of their web sdite is also very interesting…¦……….
