Section E - The Windward Mark
MR CALL E10
Rule C2.9 (18.2(a)(1)), Giving Mark-Room (overlapped)
Rule C2.9 (18.2(b)), Giving Mark-Room (rule re-applied)
Question
Blue and Yellow approach the windward mark on port tack with Blue overlapped to
windward at the zone. The mark is to be rounded to starboard.
Instead of rounding the mark, both boats slow down and continue sailing to
windward. At position 3 Yellow leaves the zone while clear ahead of Blue. Blue
remains inside the zone.
As the boats bear away they become overlapped again, this time with Yellow
overlapped outside Blue.
At position 5, flag Y is displayed by Yellow. What should the call be?
Answer
Display the green and white flag.
When Yellow first enters the zone overlapped inside Blue, she is entitled to markroom
under rule C2.9 (18.2(a)(1)). However, Yellow’s entitlement to mark-room
ceases at position 3 when she leaves the zone(see rule 18.2(b)). At this point the
boats are not overlapped.
As Blue remains in the zone she is considered the first boat to reach the zone when
rule 18.2(a) is re-applied. Blue is therefore entitled to mark-room under rule
18.2(a)(2). Yellow gives mark-room to Blue.
