I did not think that there was a renewal fee for an MMSI number. I understand that you have to renew a Ships Radio Station license periodically, and that you might have your MMSI issued along with that license. But for many of us a Ships Radio Station is not a requirement, and an MMSI can be issued without a Ships Radio Station. That, specifically, is what BoatUS does. I searched BoatUS's site and found nothing about renewing an MMSI (though you can request that one be cancelled).Failure to pay renewal fee?
So I'm still confused (nothing new!). Do MMSI numbers expire and/or require periodic renewal? I did not think that they did, but I have been wrong before (at least once or twice, I think ).
