Rule D1.1(b) Change to rule 18.2(b)

Y

Question 1
Y on starboard tack and B on port tack, both close-hauled, are approaching a
windward mark to be left to starboard. B bears away and passes astern of Y. Y luffs
slowly and nearly stops head to wind with the mark abeam. While Y is luffing, B
tacks to starboard and bears away towards the mark. Y does not give B room at the
mark, and B luffs to avoid a collision. B protests. What should the call be?

Answer 1
When Y enters the zone, the boats are on opposite tacks on a beat to windward and
no part of rule 18 applies. When B passes head to wind, she becomes overlapped
inside Y and entitled to mark-room under rule 18.2(a). However, rule 18.2(f) applies
because the overlap was created by B tacking to windward of Y.

If Y is unable to give mark-room, she is not required to give it and therefore she does
not break rule 18.2(a). B keeps clear as required by rule 11. No penalty.

If Y is able to give mark-room after B becomes overlapped, penalize Y for breaking
rule 18.2(a).

Question 2
Would the answer be different if Y is clear ahead when B passes head-to-wind?

Answer 2
Yes. Rule D1.1(b) applies and B is not entitled to mark-room. By luffing, B keeps
clear. No penalty.
