Two situations for everybody. One is just the mirror of the other. I wonder how the rules apply. So on the first one green enters the zone well before pink. Both green and pink are sailing their proper course on position 1, that is down-wind VMG sailing.
Is green clear ahead?
She entered the zone first, but pink has less distance to sail to the mark. But to me the seem to be overlapped since a perpendicular line off of each transom shows that no boat is clear astern.
But under that definition boats quite far behind time-wise could be overlapped.
Pink is a little ahead if she sailed her proper course.
So here is my interpretation.
When green enters the zone the boats are overlapped, so green is entitled to mark room.
Green needs to gybe to sail round the mark, and she wants to gybe before the mark to sail her proper course, which would require more space than mere mark room.
But 18.4 also states that it only applies to a ROW boats,
so proper course is not relevant to green and she is therefore violating rule 10 by taking more than mark room?
Would she be required to sail straight to the mark when entering the zone?
Pink is the ROW boat per rule 10, and at position 2 she is bearing away to let green sail what she thinks is greens proper course,
although green could easily have beared away and sail more slowly to the mark
For the right picture green is the ROW boat, so 18.4 does apply,
but it states that "until she gybes she shall sail no farther from the mark than needed to sail that course" which she is not,
and so in the right picture both boats are doing what they are supposed to?
Tbh i would be super stressed out if i was on board the pink boat in position 2 in the right picture.
Because I have to somehow anticipate how far green wants to go until she gybes onto her proper course.
Especially if green and pink are different types of boats, which would mean different optimal gybe angles. So as pink i would hesitate staying on the outside after it was too late to duck and while green has not started gybing yet.
Did i get this right?
