Question
Before the start Yellow and Blue, reaching on starboard tack, approach an anchored boat. When Yellow is at the obstruction, she is clear ahead of Blue. Yellow passes to windward of it, bears away alongside it, then gybes in order to sail around its stern. Very soon after Yellow gybes, Blue is still on starboard and gains a small inside overlap. Blue changes course trying to avoid contact with Yellow but there is contact. Flag Y is displayed. What should the call be?
