From the papers of Dr. Simon Hart

I have the papers of Dr. Simon Hart, from the Gemeentearchief Amsterdam in PDF form. Some of the most interesting pages are those from an Amsterdam notary, Jan Volckertszoon Oli. For the hired ship Jupiter, there is a contract and an inventory. The contracts often give the dimensions of ships, usually with the dimensions spelled out in words, rather than as numeric digits. The inventories, where they exist, are easier for me to read. The inventory for the Jupiter dates from October 1652 and gives the dimensions: 130ft x 30ft x 14ft, with a height between decks of 7ft. There is a list of guns carried, as well: 4-12pdr, 10-8pdr, 12-6pdr, and 2-4pdr guns. The Jupiter served in the Mediterranean Sea.
