Question

Y and B are overlapped, running on port tack towards a leeward mark to be left
to port. When inside the zone, Y gybes onto starboard and changes course
towards B. B is forced to gybe, and Y then luffs B away from the mark. B
protests. What should the call be?

Answer

No penalty.

From position 2, B is required to give Y mark-room.

When Y gybes she acquires right of way and B must now also keep clear. Rule
18.4 is deleted by rule D1.1(c), so Y is under no obligation to gybe. Rule 17
does not apply and Y may sail above her proper course.

Y is entitled to luff from position 3 provided she gives B room to keep clear.
