The 12 gun yacht Graaf Willem was listed anywhere

One striking thing is that now that we have access to Witte de With's journals, that the Friesland jacht Graaf Willem (12 guns) listed in Vreugdenhil as number 27 is not visible in any published or unpublished source for 1652 and 1653 that I have seen. The only Friesland jacht that is seen in the First Anglo-Dutch War is the hired 16-gun jacht Waterhond. The implication had been that Jan Coenders' ship in 1653 was the jacht, but he actually commanded a hired ship named Graaf Willem (24 guns and a crew of 85 men), as we can see in Witte de With's lists. That explains why only the 16-gun jacht is listed in the March 1653 list in Vol.I of Geschiedenis van het Nederlandsche Zeewezen.
