If anybody is even making digital or narrowband marine radios yet (not to be confused with AIS or DSC) I haven't seen them.
ITU is suggesting that eventually they want Marine VHF to use 6.25KHz channels. That limits them to digital.
No mention of NXDN or any other specific mode in the ITU documents.
And I think it'll be a while before we get there, right now, just 12.5KHz analog to squeeze some more channels in.
