Here you go:
(the lists may not be complete, but they're still great)

Dutch VOC ships:

What kind of ship
De 7 Provincien was?, that depends on which one (there have been 8
).
Most of them were ships of the line of different sizes:
And there also have been different ships named
Amsterdam,
but the one you're probably thinking of is the one of which there is a replica in Amsterdam, that one was an 18th century armed VOC cargo ship.
But there was also a first rate ship of the line called
Amsterdam between 1712-1738.
Some of my favourite (real) names for my best ships in ETW are:
Hollandia
Zeelandia
Zeven Provincien (Seven Provinces)
Gouden Leeuw (Golden Lion)
Eendracht
De Ruyter
Brederode (wide-red-one)
