I’m upgrading my license from Master 100 GRT to Master 200 GRT, and the requirement for the 200 GRT is to have 360 days at sea while holding a master/mate license and serving as master/mate. Got it, great. As I currently have my Master 100 GRT, I already have the 720 days at sea submitted. I submitted my 400ish days I have accumulated since getting the Master 100 GRT while serving as a master. I got a voicemail from someone at the NMC saying that I need to resubmit ALL my days in order to upgrade to the 200 GRT. Wondering if anyone else has had that experience? I can’t imagine someone upgrading to a 1600 GRT license going back decades and re-submitting ALL of their days since the time of getting a Six Pack or 100 GRT license…?
