At position 1;
SECTION A RULES CONTINUE TO APPLY!!!!!!
Blue is clear ahead of yellow as Blue reached the zone.
Rule 12 requires yellow to keep clear of Blue.
Since both Blue and Yellow are on the same tack, Rule 18 applies and
Rule 18.2b provides Mark-Room to Blue unless Blue passes head to wind.
At position 2;
SECTION A RULES CONTINUE TO APPLY!!!!!!
After passing the mark on the correct side for a Starboard rounding, Blue
has passed head to wind and because Blue and Yellow are no longer on the same
tack, Rule 18.2(c)(2) turned off Rule 18.2b and Blue is no longer entitled to Mark-Room.
Rule 13 applied to Blue while tacking and after Blue was on a
close hauled course, Rule 10 requires Blue to keep clear of the Starboard
tack boat Yellow boat.
Blue must take a penalty for breach of Rule 13 or Rule 10. Yellow broke Rule
14 but is exonerated because she is the ROW boat at the time of contact.
Yellow must unwind and round the mark of the correct side!
Mark-Room
Room for a boat to leave a mark on the required side. Also,
(a) room to sail to the mark when her proper course is to sail close to it, and
(b) room to round the mark as necessary to sail the course.
However, mark-room for a boat does not include room to tack unless she is overlapped inside
and to windward of the boat required to give mark-room and she would be fetching the mark
after her tack .
12 ON THE SAME TACK, NOT OVERLAPPED
When boats are on the same tack and not overlapped, a boat clear astern
shall keep clear of a boat clear ahead.
18 MARK-ROOM
18.1 When Rule 18 Applies
Rule 18 applies between boats when they are required to leave a mark on the
same side and at least one of them is in the zone. However, it does not apply
(a) between boats on opposite tacks, on a beat to windward,
(b) between boats on opposite tacks when the proper course at the mark for
one but not both of them is to tack,
(c) between a boat approaching a mark and one leaving it, or
(d) if the mark is a continuing obstruction, in which case rule 19 applies.
18.2 Giving Mark-Room
(a) When boats are overlapped the outside boat shall give the inside boat mark-room,
unless rule 18.2(b) applies.
(b) If boats are overlapped when the first of them reaches the zone, the outside
boat at that moment shall thereafter give the inside boat mark-room. If a boat
is clear ahead when she reaches the zone, the boat clear astern at that moment
shall thereafter give her mark-room.
(c) When a boat is required to give mark-room by rule 18.2(b),
(1) she shall continue to do so even if later an overlap is broken or a new overlap begins;
(2) if she becomes overlapped inside the boat entitled to mark-room, she shall also give
that boat room to sail her proper course while they remain overlapped.
However, if the boat entitled to mark-room passes head to wind or leaves the zone,
rule 18.2(b) ceases to apply.
(d) If there is reasonable doubt that a boat obtained or broke an overlap in time, it
shall be presumed that she did not.
(e) If a boat obtained an inside overlap from clear astern or by tacking to windward
of the other boat and, from the time the overlap began, the outside boat has been
unable to give mark-room, she is not required to give it.
13 WHILE TACKING
After a boat passes head to wind, she shall keep clear of other boats until she is on a
close-hauled course. During that time rules 10, 11 and 12 do not apply. If two boats are
subject to this rule at the same time, the one on the other’s port side or the one astern
shall keep clear.
10 ON OPPOSITE TACKS
When boats are on opposite tacks, a port-tack boat shall keep clear of a starboard-tack boat.
14 AVOIDING CONTACT
A boat shall avoid contact with another boat if reasonably possible. However, a right-of-way
boat or one entitled to room or mark-room
(a) need not act to avoid contact until it is clear that the other boat is not keeping
clear or giving room or mark-room, and
(b) shall be exonerated if she breaks this rule and the contact does not cause damage
or injury.
