I have done some reading on wing keels over the years. I
particularly remember Paul Yates writings on this type of foil. Paul
Yates was the designer of the Merit line of sailboats and the only 3
time winner of the MORC International Championships. He designed a
wing keel for the Merit 23. This was a full race version of the 22
(actually the same hull) He stated a number of facts with 2 that stick
out in my mind. One, the winged keels that have appeared on every
production boat have NOTHING to do design wise or performance wise with
the winged keels that were used on the 12 meter AC boats.

True. The wing keels on some racing boats are very complex
with more computer design work and testing than the average
moon rocket.


.....As it stands at the present I don't know of one planing
sportboat that uses a winged keel.

But I don't think they are sportboats, officially.
