Nutsy,

Don't sell your Wing Keel short to fast. Learn how to use it. She'll
tack upwind just fine. Just remember that you have to have a good flow
of water over the wing to make it work. A wing keel working properly up
wind will put your mast more upright, which will increase your working
sail area. Downwind, she should be as fast or faster if you watch your
hull trim (crew placement) With a good Wind, downwind it can act as a
hydrofoil. Remember Conners lost the lead to the Aussies Wing Keel on
the downward leg.

The "Old Time Puristist" see the keel as a weighted, wetted area
necessary to stop Leeway, never accepting the dynamics it adds to the
boat.

Learn to use the wing!! Hull trim is important; side to side and fore
and aft! It needs motion. Without movement it is only weight and wetted
area but so then is a deep fin keel.

A wing keel act as a hydrofoil on a displacement boat? In 70kts of
wind maybe. As far as comparing to a 12 meter AC boat pleaseeeeeeeeee.
There has never been a production boat that had a wing keel that
remotely resembled a 12 meter wing keel. The design concepts are not
even close. The design goals and functions are totally different.

Loco,

Yes!! A hydrofoil. A foil that will provide Lift. She'll not Lift clear
of the water as "Yellow Pages" does but will provide upward lift which
is a lighting force on the hull.

Loco, look at my wing in the attachment. It has a downward set to it to
help it point higher up wind. On downward we load the cockpit to get a
uplift on the hull to over come the downwind action of the sails.
