A few years back, there was a situation where a laser capsized immediately in front of the finish line, and current carried it across before the sailor righted it. There was some argument as to whether or not capsized was "in normal position", but that discussion missed the point. Take a careful read of the definition of finish:


Note the position of the first comma. "crew" or "equipment" must be in normal position, but the "hull" can be in any position. Therefore the boat in question finished when her hull crossed the finishing line, regardless of being upright or capsized.

I hope that was interesting,
