Case 50: In the photo below, Neil (W9644) has come up from astern of Roger (9174).
What limitations, if any, are there to Roger's right to luff and defend his wind?

Answer:
If you want to defend your wind these days, it is wise to do so decisively before the other boat gets an overlap or even too close to getting one. In this position, Roger will soon be hamstrung by rule 16.1: "When a right-of-way boat changes course, she shall give the other boat room to keep clear." If the two boats get much closer together laterally than they are here, they will soon reach the "locked" position in which neither boat can change course without fouling the other, something that is strategically unacceptably limiting. Moreover, a protest arising from this will be a 50-50 proposition even from the best of Committees. What I do instead, is

  • go low and not bother defending my wind with the preferred goal of out-speeding my windward opponent, or
  • I go well high as (s)he approaches from astern and I make it amply clear that I intend to make life miserable for anyone who tries my windward side. I do the latter only in rare instances when it is strategically unavoidable.
Apologies for drifting from rules into strategy!
