No hail of "starboard" is required.... "Wake up and pay attention" amounts to the same thing. You are not asserting your rights with some hail... and you are not declining your rights when you don't say a word.
Well, yes and no. The rules do not explicitly require the starboard tack boat to hail. If there's contact, however, S may find herself in trouble. Rule 14 requires all boats to avoid contact "if reasonably possible", and Dick Rose recently published an article in which he wrote that hails are a reasonable part of avoiding contact. If S could have avoided contact by hailing, and did not, then she breaks rule 14. So, although the rules are not explicit in this situation, a hail may be implicitly required.
Either way, when both boats know one another is aware of the situation, and understands the other's intentions, problems are far less likely to occur. Good communication on the water is almost always helpful.
