Has anyone done any research on ships using the records at Lloyd's of London?
I have never been there but Gregg International reprinted all the early record books in the late 1960s or early 1970s. Most major maritime libraries hold the set. If memory serves, the earliest surviving book is 1764 with a fairly complete accounting from ca.
1776 onwards. The earliest books are written in quasi-code and can easily be misinterpreted. Tonnage is not exact, sometimes rounded off to the nearest 100 tons, other times to the nearest 10 tons. Remember Lloyds was an insurance consortium and the lists only include ships insured. For example, hulls were rated A,E,I,O,U with sails, rigging & "furniture" rated 1,2,3,4,5. I can not recall seeing in the earliest books anything other that A1 or E1 ratings.
