Why don't your charts use a Mercator projection?
We DO! In spite of what anyone tells you, we do have a transverse Mercator projection on all our recent digitized charts. We have for years.
The reason for this projection is in a quote from the Grandaddy of all cartographers, Borden D. Dent, in his basic book, "Cartography: Thematic Map Design":
". . . if the area of the earth being mapped is small enough, virtually no distortion exists. . .The USCGS thus decided to use three conformal projections to map the statesthe Lambert conformal conic for states with long east-west dimensions, the transverse Mercator for states with long north-south dimensions, and the oblique Mercator for portions of Alaska."
