Question 1

Y and B are approaching a mark to be left as indicated by the arrows. Rule 17
does not apply to B. What is the latest time B may luff?

WIND
WIND
Y

B

Y

B

Answer 1

Rule 18 begins to apply when any part of the hull of either boat is in the zone.
From this moment, if B luffs and thereafter has to bear away in order to give Y
mark-room, then B breaks rule 18.2. B does not break rule 18.2 if she is able to
luff while giving Y room to sail to the mark as required by paragraph (a) in the
definition Mark-Room. Y is required to keep clear under rule 11. However, she
will be exonerated under rule 21 if she breaks rule 11 because B fails to give her
mark-room.

Question 2
If B has to bear away to give mark-room, when is she required to do so?

Answer 2

B is required to bear away promptly when the first of the boats enters the zone.
