The line on this map represents the boundary as it was described on paper. In actual practice, it was impossible from the outset to properly patrol any zone as large as Roosevelt pictured, certainly one as large as what is shown here. Also, the documents establishing the zone’s boundaries included a specific carve-out for the Azores and the practice never encroached as close to continental Africa as the map suggests. The result was that the vertical boundary, in effect, was more of a meandering S-shape from Iceland down the middle of the ocean to 20-degrees south latitude. Had they known about the mid-Atlantic Ridge in 1941, the line would have more-or-less followed that.
