On your earlier mention of a port-starboard cross...
me?... no... have I seen this on the course?.. yes. Have I screwed up and misjudged?... absolutely! Why did I get so close to a foul in the first place?... because I get sucked into the mindset of competing.... push the line...
If you were on port and crossed starboard but you CLEARLY saw that they DID have to alter their course to avoid hitting you, but did NOT yell "protest" or say anything directly to you, would you still do your penalty turn?
Let's say it was a Noob sailing who wasn't 100% sure they were in the right during this crossing maneuver...
Would this be considered "cheating" (breaking a RRS guideline) or "gamesmanship" (taking advantage of another sailor's lack of knowledge)?
