Did you mean to say that yellow was the inside boat here? That goes against what everybody has been saying...the common thought was that green is treated as the "inside" boat in this situation (which I contend is more like "will be the inside boat") all the way to even before they gybe for the gate.
Yes, Yellow is the inside boat. She got to the zone first and "owns the zone" - but only in this instance the way I drew it in Boat Scenario. A little bit of distance either way could change things drastically.
Yellow was never the inside boat. If you are required to round a mark (in this situation) to starboard, and you have an overlapped boat also to starboard, you are not the inside boat. You might be physically closer to the mark, but you are not the inside boat. This can be shown with the "string test", if each boat's track were a string and you pulled it tight, approaching the mark who would be the inside boat.
