I found where I had earlier seen the reference to "Explorer Charts" and it was in the note from ActiveCaptain:
"Regions generally cost about $29.99 for a normal large cruising area. For example, the US East Coast including Bahamas (Explorer charts) costs $29.99. Regions purchased can be loaded on all of your Android devices for only one license cost." [my emphasis]
When I look at the specific chart and it's subordinate chart list here: C-MAP Online Coverage
with "USA East Coast
and Bahamas" selected... I couldn't see anything in there that points to Explorer data. Perhaps simply 'cause I don't recognize some of the codes...
In my case, currently it's simply a matter of curiosity at the mo, since I just started playing the Plan2Nav and remembered this thread, but it seems useful to know for our future since we do intend to head
down that way eventually...
FWIW, I find myself using raster charts more often, so maybe it wouldn't hurt me to learn id advance whether MapMedia is also using Explorer data in their current NAVNet
3D raster versions for the area... Hmmm....
