Shortly: if you want to see real artefacts of the time when the genoese ruled the seas (14-17 century), don't waste time on this.
Very disappointing experience, starting with a really rude "security" guy who asked me for a ticket. I answered him that I had bought a e-ticket on the website and had already validated it at the ticket office, but he made me to the same thing again.
The museum itself might be entertaining, but not professional at all. There are some original pictures of maritime views and technical stuff from ships of the early 20th century, but all the part about the Columbus era is artificial. Also, the 16th century armour is exposed without any notes or tablets. Ironically, the early 20th century devices are numerated, but the tablets are not, so you'll not understand which is which.
The emigration part is probably the best in this place.
