It appears to be rather accurate. (I wouldn't know about the Mediterranean as I haven't been there yet.)
I have a large bathymetric map of the north and south Atlantic that was included in the January 1990 issue of National Geographic magazine.
It is by no means an official nautical navigation map but it IS highly detailed, including most of the stock port cities in SH3. It has depth markings in meters at MANY locations and it is a Mercator projection map.
You might be able to find that issue of National Geographic on Ebay pretty cheaply.
