George Parsons was born in Poole, the son of George Parsons, and was baptised at St James, Poole, 21 September 1729. His father moved to Portsmouth to take up a position as a shipwright in the Royal Dockyard in 1740. George junior began as a Quarter Boy entering 18 June 1744. He continued in the Royal Dockyard until, as a 2nd shipwright he was discharged 6 April 1763. His move to Bursledon therefore probably occurred later that year and certainly by 1764. His first employer there was a shipowner, Thomas Cooper, and a few years later, Philemon Ewer, a descendant of the pre-eminent local shipbuilder of the previous generation. He almost certainly moved into his own yard by 1774 at Bursledon Point on the Hamble, though the advertisement in 1776 for 'a good burthensome well built Sloop, about 30 tons, just finished' suggested this might have been built in partnership with Ewer. By late 1778 he was ready to build on his own account when a Navy Board letter of 19 December refers to an offer from him to build 'a Ship of 32 guns'.
The warships he built there were:
In addition to the above HMS Rattler was launched at Northam in 1795. The original contractor, Thomas Raymond went bankrupt in 1793 and Parsons took it over for which he received £3000 from the Admiralty.Quebec and Ardent were built in partnership with Robert Stares.
He leased his yard with William Raingecroft from William Allen Thackthwaite, the lease falling due for renewal at the end of 1807. For whatever reason the new lease went to Raingecroft and Richard Stiles Blake. However, ample notice must have been given as he acquired another site downstream and on the opposite shore at Warsash. With the assistance of his son John, and his grandson John Rubie he moved his entire yard including demolishing and re-erecting the large graving shed and mould loft. Two elm launchways were built as were seven houses to help accommodate his men, plus a blacksmith's shop and an inn. Warship building resumed after an inevitable hiatus and the following ships were built there:
He was one of the original shareholders in the company formed in 1797 to build a road bridge between Bursledon and Swanwick. When the construction was in danger of collapse he won the contract in 1809 for the reconstruction to the improved design of John Rennie and this lasted until a modern bridge replaced it in the 1930s.
He died on 16 April 1812, three days after the launching of Nymphe, at Salterns, his home in Bursledon. A contemporary obituary remarked that 'He has left a high character for inflexible, undeviating integrity, and, the punctuality and uprightness with which he performed his Contracts with Government, in the building of ships of war for the Navy, gained him the esteem of the Navy Board, and render his death a public loss.'
