Red will be penalized. Blue is inside right-of-way boat and Red must keep clear and give mark-room in accordance with rule 11 and rule 18.2(b). Blue is bound by rule 18.4 to sail no further from the mark than her proper until she gybes. Blue complies with these requirements. Red does not give mark-room and will be penalized for infringing rule 18.2(b). When Blue bears away hard for gybing and infringes rule 16, 10 or 11 she is exonerated by rule 21(a). See also Case 75.
