The Cherokee class was a class of brig-sloops of the Royal Navy, mounting ten guns. Brig-sloops were sloops-of-war with two masts (a fore mast and a taller main mast) rather than the three masts of ship sloops . Orders for 115 vessels were placed, including five which were cancelled and six for which the orders were replaced by ones for equivalent steam-powered paddle vessels. [1]
Many of these sailing vessels served as mail packet ships, and more than eight assisted with exploration and surveys. The best known of the class was HMS Beagle, then considerably modified for Beagle's second survey voyage under Robert FitzRoy, with the gentleman naturalist Charles Darwin on board as a self-funded supernumerary. [2] [3]
The carronade, nicknamed the "smasher" or "devil gun", was significantly smaller and lighter than conventional cannon. It was also found to have a more destructive broadside at close range, so that a smaller (and cheaper) ship could be more effective in naval actions than a much larger man-of-war. Sir Henry Peake designed a small ship to operate in both shallow and deep waters, carrying eight 16-pounder or 18-pounder carronades plus two long 6-pounder cannon as forward-mounted chase guns. [2]
He completed the design for the Cherokee class in 1807, which was approved on 26 November 1807, with the first four vessels having been ordered in March 1807 but not laid down until December; by the end of 1808 another thirty vessels had been ordered to this design. After these 34, another two were ordered in 1812 which were built of teak at Bombay. The design was revived after the end of the Napoleonic Wars, and another 78 were ordered in two batches between 1817 and 1827. The first batch of these later vessels consisted of 35 orders (of which one was cancelled) whilst the second amounted to 44 new vessels of which four were cancelled and six replaced by orders for paddle vessels.
The class was much criticised, being popularly known as 'coffin brigs', following the loss by wrecking or foundering of a number of them. [4] Almost a quarter of them were lost, and they were also nicknamed "Half Tide Rock" as they had low freeboard so the deck was frequently awash with water, and solid bulwarks preventing the water from being shed quickly.These open flush-decked ships lacked a forecastle to deflect heavy seas crashing over the bow: one was added to Beagle in 1825 before its first voyage, together with a mizzen mast which improved the handling. Despite these modifications to the design, Captain Pringle Stokes protested that "our decks were constantly flooded". [5]
Further extensive modifications were made for the second voyage of HMS Beagle. Darwin noted in his journal in April 1833 that "It blew half a gale of wind; but it was fair & we scudded before it. — Our decks fully deserved their nickname of a "half tide rock"; so constantly did the water flow over them", [5] [6] but John Lort Stokes who was on all three survey expeditions praised Beagle: "The reader will be surprised to learn that she belongs to that much-abused class, the '10-gun brigs'—coffins, as they are not infrequently designated in the service; notwithstanding which, she has proved herself, under every possible variety of trial, in all kinds of weather, an excellent sea boat." [7]
William James, in his Naval History written before May 1827, dismissed the supposed design faults, and said that it would be "surprising indeed that the navy board would continue adding new individuals by dozens at a time" to "this worthless class".[ citation needed ] A more recent naval historian, Robert Gardiner, concurs, stating that there seems to have been no particular fault in their design, but they were considered to be somewhat too small for the global duties they took on. [4] According to one experienced commander, they were not easy to sail but, "...if we put an officer who has always been accustomed to a line-of-battle-ship in to one of them, and he proves headstrong and self-sufficient, ten to one he upsets her, but in the hands of a good brig sailor, they are as safe as any other vessel". [8] Lieutenant William Bowers, who spent 12 years in HMS Helicon and Leveret, felt that the class had been unduly criticised, he thought Helicon was a crack sailer once her hold had been restowed. [4] [9] Bowers however, complained that they were wet and cramped, and he particularly bemoaned their lack of warlike capabilities, claiming they had been vastly overrated. [4] Despite these faults, the Cherokee brigs were quick when changing tack and extremely manoeuvrable, and with a crew of only 75, economical to run. [8]
Few of the Cherokee-class ships took part in sea battles of any importance. HMS Lyra and Redpole were at the Battle of Basque Roads in 1809, guiding fireships to their target in the initial attack, and the latter also participated in the Walcheren Expedition later in the same year. [10] [11] Large numbers of them went on to serve as passenger and mail carrying packet ships, running from the UK to the US and Canada. [12]
Several assisted with exploration and survey expeditions, including HMS Barracouta, which served with William Fitzwilliam Owen's survey of the African and Arabian coasts between 1821 and 1826 before being converted to a barque-rigged packet in 1829 and then being sold in 1836. [12]
The first voyage of Beagle set out in 1826 under Captain Pringle Stokes as part of Phillip Parker King's survey of South American coasts, which returned late in 1830 with Beagle by then commanded by Robert FitzRoy. Captain Henry Foster commanded HMS Chanticleer on his survey around the South Atlantic, known as his "pendulum expedition", from 1827 to 1831. Chanticleer was then intended to be used for FitzRoy's next survey expedition, but was found to be in poor condition. Instead, the Beagle was repaired and modified for its famed second survey voyage from 1831 to 1836, which took along the naturalist Charles Darwin as a self-funded supernumerary. The Beagle subsequently carried out a survey of coasts of Australia from 1837 to 1843 under John Clements Wickham and John Lort Stokes. [13]
From 1838 to around 1841 HMS Britomart, commanded by Owen Stanley, carried out survey work and other duties around Australia and New Zealand. [14] Other survey ships of this class included HMS Fairy from about 1832 to 1840, Scorpion from 1848 to 1858 and Saracen from 1854 to 1860. [12]
The first four vessels listed below were ordered on 30 March 1807, two more on 26 November 1807 and the next twenty vessels on 31 December 1807. Eight more orders were placed during 1808. All 34 were built by commercial contractors.

Six of the vessels originally ordered 25 March 1823 were swiftly re-ordered as paddle steamers in May 1824 – Alban and Carron (both at Deptford), Columbia, Confiance, Dee and Echo (all four at Woolwich).
HMS Beagle was a Cherokee-class 10-gun brig-sloop of the Royal Navy, one of more than 100 ships of this class. The vessel, constructed at a cost of £7,803, was launched on 11 May 1820 from the Woolwich Dockyard on the River Thames. Later reports say the ship took part in celebrations of the coronation of King George IV of the United Kingdom, passing through the old London Bridge, and was the first rigged man-of-war afloat upriver of the bridge. There was no immediate need for Beagle, so she "lay in ordinary", moored afloat but without masts or rigging. She was then adapted as a survey barque and took part in three survey expeditions.
A brig is a type of sailing vessel defined by its rig: two masts which are both square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships.
Vice-Admiral Robert FitzRoy was an English officer of the Royal Navy and a scientist. He achieved lasting fame as the captain of HMS Beagle during Charles Darwin's famous voyage, FitzRoy's second expedition to Tierra del Fuego and the Southern Cone.
The Voyage of the Beagle is the title most commonly given to the book written by Charles Darwin and published in 1839 as his Journal and Remarks, bringing him considerable fame and respect. This was the third volume of The Narrative of the Voyages of H.M. Ships Adventure and Beagle, the other volumes of which were written or edited by the commanders of the ships. Journal and Remarks covers Darwin's part in the second survey expedition of the ship HMS Beagle. Due to the popularity of Darwin's account, the publisher reissued it later in 1839 as Darwin's Journal of Researches, and the revised second edition published in 1845 used this title. A republication of the book in 1905 introduced the title The Voyage of the "Beagle", by which it is now best known.
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
Sir William Snow Harris was a British physician and electrical researcher, nicknamed Thunder-and-Lightning Harris, and noted for his invention of a successful system of lightning conductors for ships. It took many years of campaigning, research and successful testing before the British Royal Navy changed to Harris's conductors from their previous less effective system. One of the successful test vessels was HMS Beagle which survived lightning strikes unharmed on her famous voyage with Charles Darwin.
Rear Admiral Phillip Parker King, FRS, RN was an early explorer of the Australian and Patagonian coasts.
Admiral John Lort Stokes was a Royal Navy officer who served onboard HMS Beagle for almost eighteen years.
The second voyage of HMS Beagle, from 27 December 1831 to 2 October 1836, was the second survey expedition of HMS Beagle, under captain Robert FitzRoy, who had taken over command of the ship on its first voyage after the previous captain, Pringle Stokes, committed suicide. FitzRoy had thought of the advantages of having someone onboard who could investigate geology, and sought a naturalist to accompany them as a supernumerary. At the age of 22, the graduate Charles Darwin hoped to see the tropics before becoming a parson, and accepted the opportunity. He was greatly influenced by reading Charles Lyell's Principles of Geology during the voyage. By the end of the expedition, Darwin had made his name as a geologist and fossil collector, and the publication of his journal gave him wide renown as a writer.
Six ships of the Royal Navy have borne the name HMS Barracouta, after the fish Thyrsites atun. Another was renamed before being launched:
HMS Chanticleer was a Cherokee-class 10-gun brig of the Royal Navy. Chanticleer was launched on 26 July 1808. She served in European waters in the Napoleonic Wars and was paid off and laid up at Sheerness in July 1816. She was chosen for an 1828 scientific voyage to the Pacific Ocean. Her poor condition on her return meant that the Admiralty replaced her for the second voyage in 1831 with another Cherokee-class brig, Beagle, which subsequently became famous because of the association with Charles Darwin. Chanticleer then spent 15 years as a customs watch ship at Burnham-on-Crouch and was broken up in 1871.
The Cruizer class was an 18-gun class of brig-sloops of the Royal Navy. Brig-sloops were the same as ship-sloops except for their rigging. A ship-sloop was rigged with three masts whereas a brig-sloop was rigged as a brig with only a fore mast and a main mast.
HMS Acheron was the last Hermes-class wooden paddle sloop ordered for the Royal Navy. She was launched at Sheerness in 1838. She spent two commissions in the Mediterranean before being reclassed as a survey ship in 1847. Between 1848 and 1851 she made a coastal survey of New Zealand, the first such survey since Captain Cook. She was paid off at Sydney and was tender to HMS Calliope. She was sold at Sydney in 1855.
A nautical chronometer made by Thomas Earnshaw (1749–1828), and once part of the equipment of HMS Beagle, the ship that carried Charles Darwin on his voyage around the world, is held in the British Museum.
