Both maps below show Saint Martin highlighted. At 18° Mercator inflates Saint Martin by only about 11%, so the two maps largely agree on it. Watch what the old map does to Bahamas beside it. That contrast is why the new world map matters.
At 18°, Saint Martin sits in the band the old map drew almost honestly. It is one of the regions Mercator quietly under-represented, and that is exactly what the new Equal Earth map restores.
