HMS Chatham (1691)

For other ships with the same name, see HMS Chatham.

HMS Chatham was a 50-gun fourth rate ship of the line of the Royal Navy, the first of five such ships to be ordered in 1690 (the others were the Centurion and Chester on 20 March - six days after the Chatham - and the Norwich and Weymouth on 15 August). The Chatham was built by Master Shipwright Robert Lee at the eponymous dockyard, and launched on 20 October 1691.^[1] She was designed to the same lines as Lee's previous 50-gun ship, the Sedgemoor of 1687 - her specification was for a length of 123 ft, breadth of 34ft 3in and depth in hold of 13ft 9in, although she measured very slightly more on completion.^[1]
