The forty convoyers of 1648

After the peace treaty in 1648 that ended both the Thirty Years War and the Dutch war of independence, funding was voted to provide for forty ship, which were characterized as convoyers. I have not seen the original list of ships. All I have are several competing lists from late 1652. One of those lists, dated 28 November 1652 shows the ships as follows:

We don't have a source that shows how the ships of the Admiralty of Friesland were divided between convoyers, cruiser, and ships of the Extraordinary Equipage. We can pretty easily guess the ships in the latter category, but not the first two.
