This text analyses the influence that the diaries and maps elaborated by William Dampier along New Spain’s Pacific Coast had on subsequent expeditions from the late XVII century onwards. His experiences navigating the coast on three voyages between 1682 and 1710 were recorded in writings that became a source of valuable information for other sailors that traversed these waters. Dampier’s voyages are an example of changes in British naval and commercial policies regarding the American territories at the time, and his work became an indispensable reference to those who continued to incursion into the South Seas.
