Hello Phil, It's quite common with desktop-mapping/GIS system to handle a projected earth with no regard for 180E = 180W. It's common to add an "extra" bit of the globe, copied from the "other side of the world", so that data goes beyond 180degrees in order to give continuity. This is a real fudge since overlaid information (such as a boat position) needs to be adjusted. It's not a specific ESRI problem, MapInfo has no world projections with a variable central meridian either.

Sailing 2. Web mapping OR 3. Knowing where the edge of the world is according to Esri and have a few idle minutes, try this: http://www.vendeeglobe.org/uk/classements and click on "view map" I cannot get the map to show any detail (grid lines, features) East of 180 degrees. So am curious to see what happens in a few days when the lead boats (at 171 east) reach the edge of the world. Do like the wind and boat direction overlay though.
