Except that he only discusses fin keels. Rather like quoting Webby in a discussion about burning peat for domestic heating.Rather than get in a twist about "wetted surface" arguments etc, I can offer this expert view http://www.goodoldboat.com/reader_services/articles/keeldesign.php
Very shoal-draft boats may require fatter keels or fins in order to get the ballast as low as possible for stability
