Jan van Diemen's ship in 1631

In 1631, Jan van Diemen commanded the Rotterdam ship Eendracht. This was a vessel of 170 lasts. A ship of that size might have dimensions of 118ft x 28ft x 11.5ft. In all likelihood, the proportions would have been different. The Eendracht had been built in 1624. Her armament consisted of 2-chambered brass 24pdr, 2-half cartouwen 18pdr, 2-brass 12pdr, 2-iron 12pdr, 2-iron 10pdr, 10-iron 8pdr, and 6-iron 4 pdr. The Eendracht's crew consisted of 85 sailors. This is based on information from the Staet van Oorlog te Water for the year 1631.
