Red infringes rule 13 or rule 10 and will be penalized. At first, Red is clear ahead and rule 18.2(c) applies. However, when Red passes head to wind, rule 18.2(c) no longer applies (see last sentence of rule 18.2(c)) and rule 13 does. Even if Red completes her tack in time, she will in this case break rule 10 by not keeping clear of the starboard-tack boat. See also case 81.
