By 1664, Amsterdam had discarded their aversion to large ships

By the time that the new construction program, prior to the Second Anglo-Dutch War, had commenced in 1664, Amsterdam had accepted that larger ships were necessary to be able to effectively fight the English. Their ships were often still armed with a mixed armament on the lower deck, due to their not having solved their gun supply problem. Frank Fox says that by the time of the Third Anglo-Dutch War, the Dutch had acquired sufficient guns to be able to more heavily arm their ships. I do not have much information about this issue, but I do know that Michiel De Ruyter's flagship, the Zeven Provinciën, carried a complete lower tier of 36pdrs in the Third War.
