I read the updates to mean that the Nacra 17 was first across the line with the Viper second in the first race. Not sure which boat won the second race, sounds like Viper won the third.
I don't think, however, that the race results say too much about the designs. It is pretty clear that the level of sailor on the boat makes a tremendous difference, and not all the sailors at the trials are equal. Sarah and Matt have spent tons of time on a Viper, and I think the results above reflect that. Unfortunately, I don't think the full finishing order will be released.
