Hi Dave
I found
opencpn supports the following chart formats. Can you confirm, add where needed and also put this in the help ?
BSB / RNC (what versions?
BSB 1.1, BSB 2.0, BSB 3.0 ??)
CM93/2,
GEO (what versions? GEO/NOS, GEO/NO1 ??)
S57 (ENC)
The help does mention S57 as being the equivalent of CM93/3. Is that statement correct? I think CM93/3 is encrypted !?!
