Mistakes?

I have wondered at the seeming mistakes in the outline list of the Dutch fleet, dating from early July 1653, when the fleet was mostly near Vlissingen (Flushing). The issue is about the assignment of ships to particular directors, from some seaports. The ship Halve Maen, is said to be with the Directors of Monnikendam, whch we actually think that the ship was hired by the Directors of Edam. The ship Vergulde Zon, or Schellinkhout, seems to have been hired by the Directors of Enkhuizen, but there are several lists, including the one from early July, that say that the ship was hired by the Directors of Edam. The fact that there are several, unrelated lists with these assignments is curious. Were they all wrong? My supposition is that they were all wrong, and that they are based on some common source that gave the assignments incorrectly.
