Nope.... just looking at my notes from Dave Perry's seminar at the USSA One design meeting a few years ago... He addressed this very question.

Reading the last issue of Sailing world... the big change is to do away with this grey area of your obligation increasing until you hit the 2 boat lenght circle... Now.. no grey area... your obligations begin when the first boat hits the zone of three boat lenghs.

I quote... "an inside bot is entitled to mark-room (new def) then before she arrives at the mark she is entilted to room to sail to the mark" ie. the space she needs in the existing conditions to sail promptly to the mark in a seamanlike way. After she arrives at the mark she is entitled to room to sail he proper course. as she rounds or pass it. ...

so... I don't think the game has changed at all. It just does away with the grey area where "your obligation was increasing as you approached the 2 boat length circle"

In your example... with starbord approaching and having rights all the way... When the outer most and leading port boat hits the 3 boat lenght circle.... they have to make a hole for the port boat on their hip who would foul starbord who is jibing and going around the mark. ...

So. my interpretation.. .. if you come in on starbord... Nobody on port makes the hole... you bail and head up and protest. I think the outer most port boat will take the penalty and not the inner most port boat.
