Section E - The Windward Mark
MR CALL E5
Rule C2.9 (18.2(a)(1)), Giving Mark-Room (overlapped)
Question 1
Yellow on starboard tack and Blue on port tack, both close-hauled, are approaching
the windward mark to be left to starboard. Blue bears away and passes astern of
Yellow. When Yellow reaches the zone, she is overlapped and on the inside of Blue.
Yellow luffs slowly and nearly stops head to wind with the mark abeam. While
Yellow is luffing, Blue tacks to starboard and bears away towards the mark. Yellow
does not give room at the mark, and Blue luffs to avoid a collision. Flag Y is
displayed by Blue. What should the call be?
Answer 1
Display the green and white flag.
When Yellow reaches the zone, she is inside boat and therefore entitled to markroom
under rule C2.9 (18.2(a)(1)) until she has rounded or passed the mark. Blue
keeps clear of Yellow and gives Yellow mark-room.
Question 2
Would the answer be different if Blue completes her tack outside the zone?
Answer 2
No
