A mystery to me that I just realized that I had

I was reading a document today from May 1652 that said that Joost Bulter commanded a Directors' ship of the Stad en Lande (Groningen). All the lists say that there was one ship hired by them among the fifty Directors's ships hired in 1652. The question is which ship that was as far back as May 1652. Was it the Stad Groningen en Ommelanden with what seems to have been the original 28 guns or was it a different ship?
