Dutch ships built in 1693 seem to have been lightly armed

Ron van Maanen has data about the Noorderkwartier ship Alkmaar, built at Hoorn in 1693. The Alkmaar was built to the 15 February 1680 establishment for 70 gun ships. The dimensions of the Alkmaar were 156ft x 41ft x 15ft, with a height between decks of 7-1/2ft. The amazing thing to me is that the lower tier was all 18pdrs. The armament was 26-18pdr, 24-12pdr, 16-6pdr, and 4-4pdr guns. The Alkmaar was in service until 1712. Sources:
