What you have here is a perfect example of why dixie pn numbers make for a hollow victory. They seem to have figured in people using old tired sails and rigging into the numbers of old designs. also slower, less proficiant sailors in a given class yield a higher # for that class.
The # for the M20 seems awfully low considering they were beaten boat for boat by the tornado.
too bad the formula rich dutch system cannot achieve the status of being the world standard.
At least they all got together and had a good sailing session.
