Second voyage
For more details on this topic, see Second voyage of HMS Beagle.
The Beagle being hailed by native Fuegians during the survey of Tierra del Fuego, painted by Conrad Martens who became ship's artist in 1833.It was originally intended that Chanticleer would make the second South American Survey, but due to her poor condition Beagle was substituted for the voyage. FitzRoy, who had been considering how to return the Fuegians who had trained as missionaries, was re-appointed as commander on 25 June 1831 and the Beagle was commissioned on 4 July 1831 under his command, with Lieutenants John Clements Wickham and Bartholomew James Sulivan.[4]
The Beagle was immediately taken into dock at Devonport for extensive rebuilding and refitting. As she required a new deck, FitzRoy had the upper-deck raised considerably, by 8 inches (200 mm) aft and 12 inches (300 mm) forward. The Cherokee class ships had the reputation of being "coffin brigs", which handled badly and were prone to sinking; the raised deck gave the Beagle better handling and made her less liable to become top-heavy and capsize by helping the decks to drain more quickly so that less water would collect in the gunwales. Additional sheathing added to the hull added about 7 tons to her displacement. FitzRoy spared no expense in her fitting out, which included 22 chronometers,[5] and five examples of the Sympiesometer, a kind of mercury-free barometer patented by Alexander Adie which was favoured by FitzRoy as giving the accurate readings required by the Admiralty.[6]
In the light of the fate of Stokes and the suicide of his own uncle, FitzRoy was concerned about the lonely position of a captain at that time. His attempts to get a friend to accompany him fell through, and he asked his friend and superior, Captain Francis Beaufort, to seek a gentleman passenger who would act as a companion as well as having opportunities as a naturalist. This led to Charles Darwin joining the voyage.
Beagle was originally scheduled to leave on October 24, 1831 but because of delays in her preparations the departure was delayed until December. She attempted to depart on 10 December but ran into bad weather. Finally, on the morning of December 27, the Beagle left its anchorage in the Barn Pool, under Mount Edgecumbe on the west side of Plymouth Sound,[7] on what was to become a ground breaking scientific expedition. After completing extensive surveys in South America she returned via New Zealand to Falmouth, Cornwall, England on 2 October 1836.[8]
Third voyage

They started with the western coast between the Swan River (modern Perth, Australia) and the Fitzroy River, Western Australia, then surveyed both shores of the Bass Strait at the southeast corner of the continent. In May 1839 they sailed north to survey the shores of the Arafura Sea opposite Timor. Wickham named the Beagle Gulf and Port Darwin, which was first sighted by Stokes and which later gave its name to the city of Darwin, Australia. When Wickham fell ill and resigned, the command was taken over in March 1841 by Lieutenant John Lort Stokes who continued the survey. The third voyage was completed in 1843.
Final years
In 1845 the Beagle was refitted as a static coastguard watch vessel and transferred to Customs and Excise to control smuggling on the Essex coast to the north bank of the Thames estuary. She was moored mid-river on the River Roach which forms part of a maze of waterways in the marshes south of Burnham-on-Crouch. In 1851 oyster companies and traders petitioned for her to be removed as she was obstructing the river, and the 1851 Navy List dated 25 May showed her renamed as Southend "W.V. No. 7" at Paglesham. In 1870, she was sold to local scrap merchants "Murray and Trainer" for breaking up.
Investigations started in 2000 by a team led by Dr Robert Prescott of the University of St Andrews found documents confirming that "W.V. 7" was the Beagle, and noted a vessel matching her size shown midstream on the 1847 hydrographic survey chart. A later chart showed a nearby indentation to the north bank which could have been a dock for the Beagle. Site investigations found an area of marshy ground some 15 ft (5 m) deep matching this chart position, with many fragments of pottery of the correct period.
An atomic dielectric resonance survey carried out in November 2003 found traces of timbers forming the size and shape of the lower hull, indicating a substantial amount of timbers from below the waterline still in place. An old anchor of 1841 pattern was excavated. It was also found that the 1871 census recorded a new farmhouse in the name of William Murray and Thomas Rainer, leading to speculation that the merchant's name was a misprint for T. Rainer. The farmhouse was demolished in the 1940s, but a nearby boathouse incorporated timbers matching knee timbers used in the Beagle. Further investigations are proposed.
Their investigations featured in a BBC Television programme which showed how each watch ship would have accommodated 7 coastguard officers, drawn from other areas to minimise collusion with the locals. Each officer had about 3 rooms to house their family, forming a small community. They would use small boats to intercept smugglers, and the investigators found a causeway giving access at low tide across the soft mud of the river bank. Apparently the next coastguard station along was the Kangaroo, a sister ship of the Beagle.
