When does the new Rule 18 NOT apply?

1. When one boat is approaching the mark and one is leaving it. In this situation, even if the boats are within the Zone, the boat leaving the mark does not need to give room to the one approaching the mark. Normal rules of the road apply.
2. If a mark is also a continuing obstruction, Rule 19 applies. This is different from the previous Rule 18. New Rule 18 applies only to Marks and not Obstructions.
3. As above, if there is an obstruction, then Rule 19 applies. Only is an obstruction is also a mark does Rule 18 apply.
4. Outside the Zone Rule 18 no longer applies. It only turns on when a part of one of the boats enters the Zone.
