The only reason I can see for this added rule for the tornados is to stop already very fit sailors from going trough with an extreme and unhealthy weight loss program. It might be Pusan over again, but the odds are slim for that. I would not be surprised if many teams are planning some diet and excercise regimes better suited for a Gulag camp than olympic athletes if they qualify.

One of the german teams, the Mittelmeier brothers, was _very_ lightweight when they started sailing in the Tornado class. They would no be where they are today if there was an min. weight limit.

I think TigerMike is spot on, the heavyweights dont have that large an advantage in a breeze anymore and really suffer downwind in low/medium conditions.
