Does it, or doesn't it?

Doug, you're kidding, right? The 35s5 keel generates lift in either
version. It's a basic component of keel design.

That's not the question... did you not understand the word "up"?

Now, are you asking if the wing of the 35s5 generates lift like plane
wings on a run, the answer is, as little as possible.

In other words, they don't make the boat faster by lifting
the boat up? Is that your final answer?



Berret's broad entry for the leading edge at the base is not just about
weight. It's to distribute water flow around the wings and reduce the
plate effect at the base.

Are you sure? "to reduce the plate effect" is generally not
a design goal of any foil... otherwise why put an end plate,
in the form a wing, on it in the first place?


... some folks have altered this
with good results as the leading edge of the keel proves to be a more
important factor on other tacks.

You're saying that your keel is different on different tacks?

Gee Bubbles, I'm surprised with all your advanced knowledge,
you haven't been tapped to serve as a design consultant on
one of those mega-buck racing yacht designs.
