Ah shit, 28 days short. Do one more fishing trip?
Most tugs are small enough to be exempt from STCW requirements on domestic routes. I would recommend making getting AB your number 1 priority, then get a job on a tug and start working on STCW. In order to be an AB on STCW boats you’ll need not just Basic Training but also RFPNW and AS-D (Able Seafarer - Deck) which is a slog to get through all those onboard assessments.
