Sir William Symonds CB FRS was Surveyor of the Navy in the Royal Navy from 9 June 1832 to October 1847, and took part in the naval reforms instituted by the Whig First Lord of the Admiralty Sir James Robert George Graham in 1832.

The Experimental Squadrons also known as Evolutionary Squadrons of the Royal Navy were groups of ships sent out in the 1830s and 1840s to test new techniques of ship design, armament, building and propulsion against old ones. They came about as a result of conflict between the "empirical" school of shipbuilding, the "scientific" school led by the first School of Naval Architecture, and the "traditional" school led by master shipwrights from the royal dockyards.
