>>1385107>What is a maritime academy
It's an university-tier education facility, focused on maritime things. Most often, finishing one makes you a qualified navigator/officer/maritime engineer, depending on specialisation.
Other operate as vocation college (hence two years) that still give you high qualifications for doing this shit, but a pansy boy from the "proper" academia will outrank you if you both end up on the same vessel.
Not sure if that's even existing within other countries than Poland (and former Eastern Block in general), but there is always a fishermen technikum. Think vocative high school for fishermen, but NOT a trade school (since those don't even exist for that specific job). Basically a four-year long high school that aside teaching general stuff has bunch of trade-related subjects and finishes with additional exam giving you a certificate, should you pass the exam. And as you might have guessed, those cover stuff related with fishing, so your qualifications are pretty specific and nothing special to begin with.
