Boats A and B are approaching the starting line to start. B is a few feet clear astern of A and yelling “Up! Up! Up!” A holds her course. B then becomes overlapped to leeward of A and A immediately luffs (heads up) approximately 15 degrees and there is contact between the starboard bow of B and the port corner of A’s transom. There is no damage or injury. Both boats protest. You are on the protest committee; how would you decide this?
