A sport that includes leaping over centerboard housing every time you tack causing lots of bruises and cuts on your legs; especially in a 420 (by the way - it's a type of boat - nothing to do with pot dumbasses) and if you are lucky enough not to be cut or bruised on your legs you probably have a concussion from being too slow to duck during a tack or gybe.
The Greatest Sport in the world. Where you sail a boat via the sail catching wind. You can also race sailboats in something called a regatta this is equivelent to a swim meet on a boat, consisting of a number of races where the boat who did the best overall wins the regatta.
The stupidest of stupidest sports on earth. Where nothing but snobby assholes take part in. Where they park there beautiful European cars at the marina parking lot and then go sailing.
