Don't know if anyone else follows this, but in a nutshell today is the final race in the Finn (heavyweight singlehanded dinghy) class and Ben Ainslie is two points behind the Dane, Hohn-Christensen. Ainslie can secure victory (and his fifth gold medal) by covering Hogh-Christensen provided that doesn't let the Dutch guy win...
We should get a gold in the Star class (two man keelboat) today.
There is a good explanation of the tactical situation here:
