I think the IMG cannot be read on devices that only support G2/G2 Vision 
like the 525. The old blue chart AFAIK only had some additional 
linetypes and POIs for nautic purposes - but did not differ a lot from 
standard garmin .img maps.

I don't think that mkgmap can write anything like the G2/G2 vision 
format. Therefore IMHO the gpsmap 525 is a bad GPS to try. First try an 
older nautic GPS that can still read "old" blue chart maps. Homeport is 
the PC program for nautic maps, like Mapsource is for streetmaps. (only 
that they ask 30$ for it).
