The blue boat will be penalized for infringing rule 13. First rule 10 applies and the port-tack boat (Blue) must keep clear. It is not important if there is a hail or not. The attempt to keep clear was too late. Also, if the contact was a little later and Blue had already completed her tack just before contact, she would be penalized for infringing rule 15. Red will not be penalized for infringing rule 14, because there was no damage.
