hi, b.j.kobben
>> Well, if it's shrinking towards the poles, it basically is not a Mercator

It shrinks in a way that the whole canvas is scaled down. Considering the
Mercator is always recommended for nautical application, it should be
Mercator projection with some post process.

>> Which "nautical chart viewer" did you see this in...? 

For example, Transas's ECDIS demo, DEMO_ECDIS_2519.iso :
