How was there no foul in race 2? There was contact, therefore there must be a foul. Funny how Jobson is saying that no one thought NZ was faster. I guess he doesn't read Catsailor.com.
There was no contact. Oracle got the hook on ETNZ and luffed - to the extent she could limited by RRS 15 (Acquiring Right of Way) and 16.1 (Changing Course). ETNZ immediately responded to the luff to the extent she could at low speed and nearly head to wind, so no foul.
It's a pretty standard match racing call (MR Call B3 in the ISAF Match Racing Call Book).
