Whereas depths and heights on US charts may be expressed in meters in the
future, I doubt you'll see anything other than inland charts omit distance
scales in nautical miles. No other scale makes sense for navigation, since time
zones, lat/lon, speed (knots) etc. are based upon the Earth's diameter,
expressed in nautical miles.

>>Just before going on a little cruise earler this week, I read the post
about
the US Corps of Engineers and its metric chart. While on the boat, I was
reading a 2004 Waggoner Guide on cruising the West Coast, and in it was the
statement that "all USA navigation charts are to be converted to and issued
in
metric measurement..."
