There is no doubt in my mind that Starboard was overlapped with all three port boats. I have no idea on if the port boats would be overlapped with each other. It comes down to if Starboard gave the inside boats room and time to round in a seaman like manner.

I'll go further and say that a single handed boat needs a lot more room to turn a mark in a seaman like manner. All boats are not equal. It's damn hard to jibe, take a chute down and turn the mark at the same time single-handed. What is seaman like at a Club race is not nessessarily seaman like at a Nationals. The playing level changes.
