] Rule 18.2(c) states "...if either boat passes head to wind..., rule 18.2(b) ceases to apply. Although Artemis may have been entitled to mark room upon entering the zone, she lost that privilege (along with right-of-way) when she tacked. The rules have been this way for over a decade. I'd suggest giving the rule book another read.
Eric, isn't the rule quoted above in the context of the full 18.2 (c) rule?
18.2c
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 mark- room passes head to wind or leaves the zone, rule 18.2(b) ceases to apply.
I don't see the version of 18 (c) that you cite in the 2009-2012 rule book with 2010 changes.
I believe Boat A that tacks with the zone onto starboard has right of way over boat B that enters the zone on port after Boat A completes its tack, correct?
