I guess the point that I would make is that if you have something that is 47 metres away, you should have no interest left in the chart - only in whatever is 47 metres away!

There is an old adage that I have always applied to navigation - "You are NEVER where you think you are". As far as my navigation goes, if there is something near me that represents a danger to me, nothing beats a look out the window.
