Definitions and the Rules of Parts 2 and 4
- (a) In the definition Zone the distance is changed to two hull lengths.
- (b) Rule 18.2(a) is changed to:
-
(a) When the first of two boats reaches the zone,
- (1) if the boats are overlapped, the outside boat at that moment shall give the inside boat mark-room;
- (2) if the boats are not overlapped, the boat that has not reached the zone at that moment shall give the other boat mark-room.
If a boat passes head to wind and at that moment is clear astern of a boat in the zone, she shall give the clear-ahead boat mark-room.
