You can say the RR-working party has been busy lately. Third Call in as many weeks.
This Call is about Penalties Initiated by Umpires—Breach of Sportsmanship.
You can read it here
Basically the call states that an emotional response to a penalty or situation is still ok, but if it escalates in abuse or insult, umpires should initiate a further penalty or protest.
My skin is been callused by "yellow flag duty" and I have 'closeble' flaps over my ears. So far I haven't felt the need to consider penalizing a boat for these issues. But I can imagine it will happen.
How about you?
