No doubt this will not be your typical snotty-yachtie race in boats that don't go much faster than grandma can run. Non-sailors might even bother watching this time.

The man part way up the mast gives a really nice perspective on the size:

From the Boeing website:

So the makers think it has two wings...

Wow!...They spin that 90' around like a darn Hobie cat.

OK Question...how the heck do you reduce wing?

Heh . . . you don't! At least, not in the classic sense. The only way to de-power is to feather, and I'm sure they'll be reluctant to do so under the pressure of a head-to-head match race. Their task is to sail her on the razor's edge between maximum performance and catastrophic disaster!

Should be fun to watch, don't ya think?

I hope it sails faster than ever, I fear it's going to snap in two like a cheap chopstick.

We'll have to see. It sure looks nice, though.

I don't think they have to reduce wing. If you look closer these are in fact two separate wings on two "masts"(?).
There is a gap between them and I reckon that both wings can act like flaps to direct the airflow. If they can make the gap bigger it will help to reduce the efect of gusts and make the wing less efficient in strong winds.

Also the black winglets/vortex generators in the middle are attached to the middle mast and the main wing has slots implying that it can move just like the flaps on the airplane. Therefore it can also work as a spoiler.

The second wing is divided into sections which will allow for various angle settings. This machine can in fact hove to if required This is not just a wing. It is as a very complicated wing. I canít wait to see it flying...
