Protest them under rule 12 (port startboard) when u have a p/s incident. They are pretty hard to get out of if they are wrong, they should hopefully lose that.
Numbers dont mean anything, there should only be one of thier crew in the protest room. Protest the rc and protest comitee if theyre leeting more in.

And if they threaten you any more or tell you to gte lost protest them under rule 69 and get them banned from sailin
