HMS Cambridge was an 80-gun third rate ship of the line of the Royal Navy, launched at Deptford Dockyard on 21 December 1695. Designed as part of an experimental ship program in response to concerns about French naval expansion, she was built with a traditional two full-length gun decks topped by an additional half-length deck to increase her armament. This innovative but flawed design resulted in a ship that was top-heavy and had poor sailing qualities. The increased weight from the half deck raised her draught, causing her lower gun ports to be at risk of flooding, and her high center of gravity made her unstable in strong winds. In 1713, she was rebuilt at Woolwich Dockyard to address these issues, following the 1706 Establishment standards. Her reconstruction, overseen by shipwright Jacob Acworth, included a wider hull, a full upper deck, and a lowered mast yard to improve stability. The rebuilt vessel measured approximately 156 feet in length overall, with a beam of about 43 feet 8 inches, and a hold depth of 17 feet 8.5 inches. Her tonnage was 1,286 tons burthen, and her construction cost was £17,117, including fittings. Her armament was consistent with her original design, featuring 26 32-pounder cannons on the lower deck, 26 18-pounders on the middle deck, and 22 6-pounder guns on the upper deck, along with six additional 6-pounders on the quarterdeck, maintaining her 80-gun complement. Her peacetime crew numbered around 360 men, rising to 520 during wartime. HMS Cambridge saw limited active service. During the War of Jenkins' Ear, she participated in Sir John Norris' 1740 expedition to the Bay of Biscay and the Battle of Toulon in 1744. Prior to these engagements, she was involved in impressment operations along the Irish coast, which proved to be ineffective due to poor quality recruits. In 1740, her crew suffered from illness and inadequate manpower, reflecting her ongoing issues with stability and seaworthiness. After several years of service and considerations for rebuilding that were ultimately inconclusive, HMS Cambridge was broken up at Chatham Dockyard in 1750, marking the end of her maritime career.
