Many, many ways and times.

There is a book about sailing physics by C.A. Marchaj. (I hope I got the
author's name right.) It will have enough information about sailing
physics to satisfy even a graduate level physics person.
good luck and have fun sailing.

In books about sailing, I have read that the keel, going through water,
produces lift in a similar way to a sail. Given that water is a
non-compressible medium, I wonder how this can be so. Has it ever been
documented?

The book is "Sailing Theory and Practice", C A Marchaj , Dodd Mead & Co NY

He has another excellent book: "Stability, the Forgotten Factor" on modern
yacht design which is very good as well.

His ideas (some iconoclastic) are backed up 100% by referenced research. A
tough chew, but wholesome and nutritious.
