The frigates Overijssel and Utrecht were of the 100 ships of 1652

I was surprised to learn that the old Rotterdam frigates Overijssel and Utrecht were among the 100 ships funded in early 1652 for the First Anglo-Dutch War. These were both built as warships, and were of the same design as the frigate Gelderland, which was one of the 40 convoyers funded in 1648, at the peace. A list dated 28 July 1652 and another dated 28 November 1652 both confirm this fact.
