Here’s a situation that came up at the 2012
Baker Trophy – the US High-School Team Race Championship. It was at the leeward mark (Mark 3) of a digital-N
course; the next leg was a beam reach toward Mark 4.

Meanwhile, B had sailed toward the mark, fully expecting
that A would be able to hold X away long enough for B to round in first
place. Caught by surprise when this
didn’t happen, she failed to react quickly enough and ended up caught on
starboard tack at the mark, with no mark-room. So she decided to make the best of a bad
situation and jibe inside X and A, hitting X and the mark.
Imagine you’re an umpire and you manage to see all this
correctly. What is your call? I’ll give you a little time to come up with
your answer (though of course if you were actually an umpire you would have no
time), and publish my answer in the next posting.
