Which rule would you rewrite

Not at all.  I can't remember when it was but it was something that Andy Rice discussed in his column. It is no different that the situation you get at the bottom of a run (starboard gate mark) where boats converge on opposite gybes and a port boat can have an inside overlap and hence rights over a starboard boat.  We are happy with this where the closing speeds are higher, and options for getting out of the way are fewer.  It will change the tactics required a lot, but if you've played a blinder up the left, is it fair that you have to give it all up at the top mark because there is no gap for you to file in on?  Granted the rules are what they are, and right or wrong they are the same for everyone, but the question is what would you like to change?  I would certainly like to try a few races like that, just to see how it works in practice.
