Question 1

Three boats B, X and Y, all on port tack, are approaching a gybe mark directly
astern of each other. X enters the zone clear ahead of B, and then stops just
inside the zone. Y bears away onto a course to pass to leeward of B. B then
bears away to pass to leeward of X, and Y and B become overlapped. When Y
and B become overlapped, B is no longer able to pass to windward of X. Y bears
away to avoid B and protests. What should the call be?

rule 18.2(b). At position 1, B has right of way over Y and rule 19.2(a) allows her
to pass the obstruction X on either side. When B and Y become overlapped, Y
