HMS Dolphin (1751)

HMS Dolphin was a 24-gun sixth-rate frigate of the Royal Navy. Launched in 1751, she was used as a survey ship from 1764 and made two circumnavigations of the world under the successive commands of John Byron and Samuel Wallis. She was the first ship to circumnavigate the world twice. She remained in service until she was paid off in September 1776. She was broken up in early 1777.

Construction

Built to the 1745 Establishment, Dolphin was originally ordered from the private yard of Earlsman Sparrow in Rotherhithe (under contract dated 7 October 1747). Following Sparrow's bankruptcy in 1748, the order was moved to Woolwich Dockyard. In order to reduce the likely incidence of shipworm, Dolphin's hull was copper-sheathed ahead of her first voyage of circumnavigation in 1764.

Early service

Not long after her commissioning, the hostilities of the Seven Years' War had escalated and spread to Europe, and in May 1756 Britain declared war on France of the Ancien Régime. Dolphin was pressed into service throughout the conflict, and was present at the Battle of Minorca in 1756 when a fleet under Admiral John Byng failed to relieve Port Mahon, Britain's main base in the Western Mediterranean (as a result of which Byng was later court-martialled and shot).
