In the rating system of the British Royal Navy used to categorise sailing warships, a first rate was the designation for the largest ships of the line. Originating in the Jacobean era with the designation of Ships Royal capable of carrying at least 400 men, the size and establishment of first-rates evolved over the following 250 years to eventually denote ships of the line carrying at least 80 guns across three gundecks. By the end of the eighteenth century, a first-rate carried no fewer than 100 guns and more than 850 crew, and had a measurement (burthen) tonnage of some 2,000 tons.
In the rating system of the Royal Navy used to categorise sailing warships, a sixth-rate was the designation for small warships mounting between 20 and 28 carriage-mounted guns on a single deck, sometimes with smaller guns on the upper works and sometimes without. It thus encompassed ships with up to 30 guns in all. In the first half of the 18th century the main battery guns were 6-pounders, but by mid-century these were supplanted by 9-pounders. 28-gun sixth rates were classed as frigates, those smaller as 'post ships', indicating that they were still commanded by a full ('post') captain, as opposed to sloops of 18 guns and less under commanders.
HMS Griper was a Bold-class gun-brig of the British Royal Navy, built in 1813 by Mark Williams and John Davidson at Hythe. She participated in the 1819 expedition to the Arctic led by William Parry, made a voyage to Greenland and Norway in 1823, and took part in Parry's third expedition in 1824 as a support ship. Her crew in 1819, 1823, or 1824, qualified for the "Arctic Medal", which the Admiralty issued in 1857. She was eventually broken up in 1868.
HMS Argo was a 28-gun sixth-rate frigate of the Royal Navy. The ship was one of the Coventry class, designed by Sir Thomas Slade as a development of based on HMS Lyme, "with such alterations as may tend to the better stowing of men and carrying for guns."
HMS Coventry was a 28-gun sixth-rate frigate of the Royal Navy, launched in 1757 and in active service as a privateer hunter during the Seven Years' War, and as part of the British fleet in India during the Anglo-French War. After seventeen years' in British service she was captured by the French in 1783, off Ganjam in the Bay of Bengal. Thereafter she spent two years as part of the French Navy until January 1785 when she was removed from service at the port of Brest. She was broken up in 1786.
HMS Drake was an 8-gun snow-rigged sloop of the Royal Navy, launched in 1741 as the first of three Drake class sloops constructed for convoy duty during the Anglo-Spanish War of Jenkins' Ear from 1739 to 1742. After limited service off the Channel Islands, she was sailed to Gibraltar where she was wrecked in 1742 while under the temporary command of her first lieutenant.
HMS Trial or Tryall was a 10-gun two-masted Hind-class sloop of the Royal Navy, designed by Joseph Allin and built by him at Deptford Dockyard on the Thames River, England. She was launched on 17 July 1744. She and her sister ship, Jamaica, were the only sloops to be built in the Royal Dockyards between 1733 and 1748.
The Baltimore class was a class of three sloops of wooden construction built for the Royal Navy during 1742-43. Two were ordered in 1742 and a third in 1743, and constituted a further increase in size from the 200 burthen tons which had been the normal size from 1728 to 1739; Baltimore was built to a design by Charles Calvert, 5th Baron Baltimore, one of the members of the Admiralty Board at that time; it is uncertain whether the other two ships were built to the same design, or to the same overall dimensions but to a design prepared by Jacob Allin, the Surveyor of the Navy.
HMS Hawk was an eight-gun snow-rigged sloop of the Royal Navy, the second of three Drake class sloops constructed during the Anglo-Spanish War of Jenkins' Ear. Launched in 1741, her principal service was as convoy escort and patrol in the Irish Sea. She was broken up at Deptford Dockyard in 1747.
HMS Swift was an 8-gun snow-rigged sloop of the Royal Navy, the last of three Drake class sloops constructed during the Anglo-Spanish War of Jenkins' Ear. Launched in 1741, her principal service was as convoy escort and patrol off North Carolina and in the North Sea. She was lost at sea on 31 October 1756.
HMS Wolf was a 14-gun snow-rigged sloop of the Royal Navy, launched in 1742 as the first of three Wolf-class sloops constructed for action against Spanish privateers during the War of Jenkins' Ear.
HMS Perseverance was a 36-gun Perseverance-class frigate of the British Royal Navy. She served on the North American station until 1787, after which she returned to England, where she was refitted at Portsmouth. In 1789 Perseverance was sent to the East Indies; she returned to Portsmouth in 1793, when she was laid up before finishing her career there as a receiving ship. She was sold and broken up in May 1823.
HMS Blast was a Serpent-class bomb vessel of the Royal Navy, one of ten such vessels commissioned in 1695 to support land assaults on continental ports. Over a 30-year period she saw service in the fleets of Admirals Berkeley and Byng and took part in the British victory at the Battle of Cape Passaro in 1718.
HMS Granado was a Serpent-class bomb vessel of the Royal Navy, one of ten such vessels commissioned in 1695 to support land assaults on continental ports. She saw active service in the Nine Years' War as part of the fleets commanded by Admirals Berkeley and Rooke. She was subsequently assigned to cruising duties in the Mediterranean.
HMS Thunder was a 13-gun bomb vessel, used by the Royal Navy for cruising and land bombardment duties between 1719 and 1734. Constructed for the Spanish Navy, she was captured by the British in 1718 and recommissioned for Mediterranean service, including as part of Admiral Charles Wager's fleet. Despite extensive repairs she was eventually declared unseaworthy, and was broken up at Deptford Dockyard in 1734.
HMS Infernal was an 8-gun bomb vessel of the Royal Navy, constructed in 1757 and in service until 1763. Designed by Thomas Slade, she was the prototype for six subsequent Infernal class bomb vessels which saw service in the Mediterranean and the West Indies during the Seven Years' War with France. In 1760 she was refitted as a sloop and returned to active service in the Caribbean.
HMS Endeavour was a 4-gun bomb vessel of the Royal Navy, purchased in 1694 but sold out of service the following year.
The Alderney class was a class of three sloops of wooden construction built for the Royal Navy between 1755 and 1757. All three were built by contract with commercial builders to a common design prepared by William Bately, the Surveyor of the Navy.
HMS Swallow was a 14-gun Merlin-class sloop of the Royal Navy. Commissioned in 1745, she initially served in home waters as a convoy escort and cruiser before sailing to join the East Indies Station in 1747. There she served in the squadron of Rear-Admiral Edward Boscawen, taking part in an aborted invasion of Mauritius and the Siege of Pondicherry. In 1755 Swallow returned home to join the Downs Station, as part of which she fought at the Raid on St Malo, Raid on Cherbourg, and Battle of Saint Cast in 1758. She was also present when the French fleet broke out of Brest prior to the Battle of Quiberon Bay in 1759.
