HMS Prince of Orange was a 70-gun third rate ship of the line of the Royal Navy, built to the 1719 Establishment at Deptford Dockyard, and launched on 5 September 1734. In 1748, Prince of Orange was cut down to a 60-gun ship, a role in which she remained until being converted into a sheer hulk in 1772. After nearly 40 years service in this capacity, she was finally sold out of the navy in 1810. The 'Prince of Orange' was part of the British Fleet at the capture of Louisbourg in 1758. David Ramsay, fur trader, revolutionary War soldier, and Indian-killer was a crew member of Prince of Orange at both the battle of Louisbourg and battle of Quebec.
