Rule 17: I said that the opposing boat did not
luff us up because we had pointed out to them (loudly) that they had
approached from astern for the overlap. Michal K commented that RRS 17 says that the boat which establishes overlap from clear astern cannot
luff above its proper course - however, there is no proper course before the starting
signal - so they could have luffed us up all the way to head to wind.
If that is the case, the
starboard reach along the line before the start of a reach is a weak strategy
as you can be luffed head to wind (and lose control of the start).
Rule 11: I had described how we luffed up the opposing boat on a downwind leg and gained a big advantage. Rob V sent me a clarification by email.

“Beware in situation 4: the way you've drawn
it, overlap was probably established from clear astern within 2 boat lengths
lateral distance. In that case, red (Alex's boat) would be subject to RRS 17 and would not be
allowed to sail above its proper course.”
“In the actual situation, you
weren't overlapped just after the mark. The boats diverged and an overlap was
established at a distance that I judged to be larger than 2 boat lengths…
Hence, you were not subject to RRS 17 and were allowed to luff. You did so and
forced the other boat to follow your luff (RRS 11). At every change of your
course, you had to be careful to give the other boat room to keep clear (RRS
16.1). This you did… The other boat should of course have gybed or taken its
spinnaker down much earlier because it was fairly obvious you would luff.”
