Wrong.

The older Mac 26 was built in a variety of models, some of which had
daggerboards, some of which had minimally ballasted centerboards. None
had "swing keels" nor did the Mac 26X.

There was an earlier yet boat called the Mac 25 which *did* have a swing
keel and a very similar hull to the old water ballast M26.

You don't know what you're talking about. Go hang out on one of the Mac
discussion lists and learn.
