Another source that Vreugdenhil just skimmed, lightly, is the "Staet van Oorlogh te Water voor den Jaere 1654" that includes a great deal of armament information. It also has some useful information about captains. Sadly, it lacks any useful crew size data, for some reason. Even the older lists, at least for Rotterdam, and to a certain extent, Amsterdam and the Noorderkwartier, have armaments, crews, and size in lasts for many ships. I have lists for 1628, 1629, 1631, and 1633, although I have barely looked at them (as they are not as high a priority as the First Anglo-Dutch War).
