First the blue boat (port tack) infringes rule 10, because she does not keep clear. Then Red luffs up to minimze the damage and to comply with rule 14. Thereby she infringes rule 13 and makes contact with the other boat. But because Red was compelled by Blue to infringe the rule, she will be exonerated from this infringement in accordance with rule 64.1(a). Only Blue will be penalized.
