John Barnard (1705–1784) was an 18th century English shipbuilder serving the Royal Navy.
He was born in 1705 the son of John Barnard a shipwright in Ipswich (1665-1716) and his wife Mary (1668-1734).
[2] From 1733 he was employed at St Clement's Yard in Ipswich, but is only formally listed as a Royal Navy employee from April 1740 when as a Master Shipwright he launched HMS Bideford.
Inflation in Great Britain was unusually high (at around 13%) in 1780, and this would also cause problems on keeping to a stated contract price on a job which often took two or three years to complete.
He also had opened a third yard (almost certainly with his own finance rather than funded by the Royal Navy) at Rotherhithe around 1780.
