Summer challenge, 2017: How to make money in C17th commercial shipping?
This summer the MarineLives project team is looking at the drivers of profit and loss in C17th commercial shipping. We will publish as we go and welcome comments, contradiction, and offers of help and data.
Early results from our work
The average age of ships for which we have age and tonnage data is 6.1 years (n=37), whereas the average age of ships for which we have age data accurate to the year for which we have no tonnage data is 7.1 years (n=41).
Dr Ian Friel has shared with us a summary of data from his unpublished survey of High Court of Admiralty documents from the 1580s. His data are for a period forty to eighty years earlier than our own High Court of Admiralty data. Ian's survey found ages for thirty-nine ships, with an average age of nearly fifteen years and twenty-nine of them of ten years or more in age.
Comparison of textual and numerical data for 1630-1670, with the bulk of the data from the 1650s, suggest Admiralty Court witnesses regarded ships aged between zero and five years as "new" and ships of fourteen years and above as "old".
The average crew size for the larger dataset is 47.3, including six exceptionally manned men of war with 275 or more men per ship (n = 172). The average crew size for the smaller dataset, where we have crew number and ship tonnage is 36.5 (n=116).
Our volunteers
MarineLives is a collaborative volunteer driven project. The project started as a spinoff from a National Archives hackathon in early 2012. We are dedicated to the collaborative transcription, linkage and enrichment of primary manuscripts from the High Court of Admiralty, 1650-1669 (with some excursions into data from the 1630s and 1640s).
Currently, we have just over 10,000 images available (29 GB) and 11,400 pages of full text transcriptions on the MarineLives wiki.
Please contact us if you would like to learn more about this summer's project and how you can help, or if you would more generally like to learn about the work of MarineLives volunteers.
We would like to recognise and thank all those who have contributed to our project (in alphabetical order), whether as volunteer transcribers, annotators, commentators, advisors, interviewees, or PhD Forum participants.
