Jobs you can do with it

Ship Captain
Ship captains command a vessel and its crew, carrying legal responsibility for everyone aboard, the cargo and the ship itself.
What else you need
The diploma must be completed with an AMSA-approved training provider. It is only one requirement for an AMSA Master certificate of competency: you also need extensive qualifying sea service, a prior certificate, medical fitness and an oral exam. The award alone confers no certificate. This catalogue groups awards: verify the chosen provider, programme and intake; the family-level link is not confirmation that every offering is approved.
