Had an issue today...

Leeward mark. Boat 1 is on port tack, Boat 2 is on Starboard
boats on oppostite tack heading toward the leeward mark. boat 1 Blue on port tack in side the zone Position 1 boat 2 red on startboard tack out side the zone position 1. boat 2 is able to accelerate on a puff inside of boat 1 at position 2 prior to the mark and begin rounding the mark at position 3.. so the question is Does being on starboard tack overrule the zone Boat 1 protested boat 2
multiple rules applies #10, and #18
rule 10 is pretty cut and dry...
10 ON OPPOSITE TACKS
When boats are on opposite tacks, a port-tack boat shall keep clear of a starboard-tack boat.
but we must also consider Rule 18 so first we look at when rule 18 is turned off. in this case rule 18 is ON
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
so now we need to look at 18.2
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), she shall continue to do so even if later an overlap is broken or a
new overlap begins. However, if the boat entitled to markroom 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 and, from the time the overlap began, the outside boat has been
unable to give mark-room, she is not required to give it.
SO rule 18.2b the important part is If a boat is clear ahead when she reaches the zone, the boat clear astern at that moment shall thereafter give
her mark-room. the question is does Starboard tack overrule port tack, irregardless of the zone...
