The Amsterdam ship Haarlem

From this list that I just received that is dated 15 November 1653, there is another list of Amsterdam ships. I was looking at the list again, and the list of guns for the 40-gun ship Haarlem is striking: 8-18pdr, 18-12pdr, 10-6pdr, and 4-4pdr guns. The weight of broadside is 218 lbs. Compare that with the broadside weight for the Vereenigde Provincien, another 128ft 40-gun ship, which fired a broadside of 232 lbs, as the ship carried 4-24pdr and 22-12pdr guns, along with 8pdr and 6pdr guns. The heavy battery on the Haarlem did not really provide a greater broadside, although the 18dpr guns would be harder-hitting than 12pdrs.
