No. The course sailed by Blue is not correct. When pulled tight, the string representing her wake would not cross the finishing line in the correct manner. Because Blue crosses the finishing line the second time from the course side, she has finished. But she has not complied with rule 28.2 (Sailing the Course). Blue can correct her mistake in accordance with rule 28 by rounding one of the finishing marks and crossing thereafter the finishing line from the course side.
