Timbo... what part of port tack shall keep clear of starboard do you want to argue with?

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.

Starboard is NOT DUCKING PORT.... She is avoiding a collision with PORT.... It's a foul by port. Port put her self in that position and took the risk.. So... pay the piper.

As windy noted... Self policing... means YOU call the foul on yourself.... you don't have to hear protest if you know you fouled him.
If there was some doubt... He can help you out by telling you... Protest.... If he says protest and you think you were clear ahead... better have a witness who has the proper angle to disprove Starboard's claim that they altered course to avoid a collision.

The rules are black and white here to make the penalty on Port large enough so that she is conservative in her time and distance judgments.

ps
In catamarans... its of dubious value to tack and try to lee bow starboard.... so you would prefer port to tack below you and get shot out the back as opposed to ducking and getting a shift or more pressure on port tack.

If they are clear ahead of you... they are winning for the moment.... If they want to tack on you and get your air..... that's what winning gets you.

Maybe's cause boats to go boom!
