Ron van Maanen has the details of the Rotterdam frigate
Delft, built in 1659 and captured by the English at the Battle of Lowestoft, in 1665:
The frigate Delft, built in 1659
Length from stem to sternpost: 111ft-3in
Beam: 27ft-3in
Hold: 11ft-2in (or 13ft)
Height between decks: 6ft-6in
36 guns (16 March 1665): 8-12pdr, 22-8pdr, 2-6pdr, and 4-2pdr
Dr. Weber gives the dimensions as: 111ft-3in x 27ft-3in x 10ft-4in
Ron van Maanen says the dimensions are in Maas feet, although that seems improbable. The English length of 94ft does seem quite long for a Dutch length of 111ft-3in. My estimate of the English length on the keel is 84ft. The beam and hold are quite plausible, using my system for converting between the two measurement systems.
