Sir Thomas Slade (1703/4–1771)
was an
English naval architect, most famous for designing
HMS ''Victory'',
Lord Nelson's flagship at the
Battle of Trafalgar in 1805.
Early life
He was the son of Arthur Slade (1682–1746) and his wife Hannah Moore. His paternal uncle was Benjamin Slade, Master Shipwright at Deptford Dockyard.
Career outline
Like many who rose to the pinnacle of the design of British sailing warships, Thomas Slade began as a shipwright in the Royal Dockyards. His uncle Benjamin Slade was Master Shipwright at Plymouth Dockyard (a master shipwright was responsible for all ship construction and repair at the dockyard in which he served).
In 1744 Thomas became Deputy Master Shipwright at
Woolwich Dockyard. On 22 November 1750 he replaced his uncle, who had died that year, as Master Shipwright at

. On 27 May 1752 he was transferred temporarily back to Woolwich Dockyard as Master Shipwright, and from there to
Chatham Dockyard on 17 June 1752 and subsequently on 15 March 1753 to
Deptford Dockyard, where he remained until 5 August 1755.

He was appointed Surveyor of the Navy in August 1755 by
George Anson, First Lord of the
Admiralty, serving until his death in February 1771. For the first decade, he shared the appointment with William Bately, formerly the Deputy Surveyor of the Navy, until the latter's retirement in June 1765. On Bately's retirement, John Williams was appointed to share the post. Nevertheless, Slade was clearly the senior surveyor throughout his tenure.
He was knighted on 27 January 1768.
Achievements
According to
N. A. M. Rodger:
The ships which edesigned...were admirably suited to Britain's strategic requirements...By common consent, Slade was the greatest British naval architect of the century...it was generally agreed (even by themselves) that his successors, though competent designers, never matched his genius.
During this tenure, Slade was responsible for several major design changes. He produced a 'generic design' that was used as a template for the

He also designed

Slade also designed smaller vessels, such as the 10-gun

In 1758, Nelson was born, who would die on her decks at Trafalgar.
