Woodes Rogers was the eldest son and heir of Woods Rogers, a successful merchant captain. Woodes Rogers spent part of his childhood in Poole, England, where he likely attended the local school; his father, who owned shares in many ships, was often away nine months of the year with the Newfoundland fishing fleet. Sometime between 1690 and 1696, Captain Rogers moved his family to Bristol. In November 1697, Woodes Rogers was apprenticed to Bristol mariner John Yeamans, to learn the profession of a sailor.
The War of the Spanish Succession started in 1702, during which England's main maritime foes were France and Spain, and a number of Bristol ships were given letters of marque, allowing them to strike against enemy shipping. At least four vessels in which Rogers had an ownership interest were granted the letters. One, Whetstone Galley, named for Rogers' father in law, received the letters before being sent to Africa to begin a voyage in the slave trade. It did not reach Africa, but was captured by the French. Rogers suffered other losses against the French, although he does not record their extent in his book. He turned to privateering as a means of recouping these losses. In late 1707, Rogers was approached by William Dampier, a navigator and friend of Rogers' father, who proposed a privateering expedition against the Spanish. This was a desperate move on the part of Captain Dampier to save his career. Dampier had recently returned from leading a two-ship privateering expedition into the Pacific, which culminated in a series of mutinies before both ships finally sank due to Dampier's error in not having the hulls properly protected against worms before leaving port. Unaware of this, Rogers agreed. Financing was provided by many in the Bristol community, including Thomas Goldney II of the Quaker Goldney family and Thomas Dover, who would become president of the voyage council and Rogers' father in law. Commanding two frigates, Duke and Duchess, and captaining the first, Rogers spent three years circumnavigating the globe. The ships departed Bristol on 1 August 1708. Dampier was aboard as Rogers' sailing master. Rogers encountered various problems along the way. Forty of the Bristol crew deserted or were dismissed, and he spent a month in Ireland recruiting replacements and having the vessels prepared for sea. Many crew members were Dutch, Danish, or other foreigners. Some of the crew mutinied after Rogers refused to let them plunder a neutral Swedish vessel. When the mutiny was put down, he had the leader flogged, put in irons, and sent to England aboard another ship. The less culpable mutineers were given lighter punishments, such as reduced rations. The ships intended to force the chilly Drake Passage off the tip of South America, but expedition leaders soon realised that they were short of warm clothing and alcohol, which was then believed to warm those exposed to cold. Considering the latter the more important problem, the expedition made a stop at Tenerife to stock up on the local wine, and later sewed the ships' blankets into cold weather gear. The ships experienced a difficult inter-oceanic passage; they were forced to almost 62deg South latitude, which, according to Rogers, "for ought we know is the furthest that any one has yet been to the southward". At their furthest south, they were closer to as-yet-undiscovered Antarctica than to South America.
