Just notices that both boats rounded the windward mark from the opposite direction than listed in the Sailing Instructions, probably means nothing but isn't that clumsy?
Too bad I had to go home yesterday, the prices of the spectator boats have dropped by 50%!

The RC told them to do a starboard rounding at the start.
I wanted to go out yesterday but I would have definitely missed my flight home.

The wind was definitely faster yesterday, although I also think it has quite a bit more surface then the A5 normal mainsail.
