C2.6
Rule 13 is changed to:
13 WHILE TACKING OR GYBING
13.1 After a boat passes head to wind, she shall keep clear of other boats until she is on a close-hauled course.
13.2 After the foot of the mainsail of a boat sailing downwind crosses the centreline she shall keep clear of other boats until her mainsail has filled or she is no longer sailing downwind.
13.3 While rule 13.1 or 13.2 applies, rules 10, 11 and 12 do not. However, if two boats are subject to rule 13.1 or 13.2 at the same time, the one on the other’s port side or the one astern shall keep clear.
