Strange Tonnage

How do I get a job as “Chief Mate” on that vessel so I can get unlimited master?

Yes, I know the USCG only requires one 100 ton Master, and one 100 ton Mate or this vessel.

However, those officers get 4000 ton seatime allowing an upgrade to an unlimited tonnage master’s license.

Oh the wonders of the USCG tonnage and licensing debacle.
