Ron van Maanen has a bit more information about the old Rotterdam 40-gun ship Gelderland

I was looking at Ron van Maanen's list and saw that he had some additional information about the old (in 1652) Rotterdam ship Gelderland (40 guns). This is the ship that was commanded by Michiel Fransz van den Bergh during the First Anglo-Dutch War. The usual dimensions that have been published are in Maas feet of 12 inches: 118ft x 28ft x 12-1/2ft. My estimated dimensions in Amsterdam feet of 11 inches are: 128-1/2ft x 30-1/2ft x 13-1/2ft. Ron says that the ship was 250 lasts, which seems to be the standard, if nominal size for the 40-gun ships of about 128ft. The ship was built in 1634. Ron has the list of guns for three dates: 11 November 1652, 25 March 1653, and the 1654 list from the Staet van Oorlog te Water. The lists are probably all the same armament. The first and third gun lists are: 18-18pdr, 12-12pdr, 8-6pdr, and 2-4pdr. The middle list has the following: 2-18pdr, 16-16pdr, 12-12pdr, 8-6pdr, and 2-4pdr. This seems like it could be more correct, and the others included the 16-pdr guns as 18 pdrs. Sources:
