I was also wondering how promotions work? For the last several patrols, I've been unable to promote anybody. I keep getting a message that I'm already maxed out on petty officers and officers.

So there's no way to promote seamen, apparently? I would have assumed that promoting them e.g. from Seaman 3rd Class to Seaman 2nd Class would perhaps improve their abilities, even if they cannot have a specialization like an officer.
