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.
