Mocha Island is a Chilean island located west of the coast of Arauco Province in the Pacific Ocean. It is approximately 48 km2 (19 sq mi) in area, with a chain of mountains running north–south. Mocha Island National Reserve covers approximately 45% of its surface. The island is the location of numerous historic shipwrecks. In Mapuche mythology, the souls of dead people travel west to visit this island.

Dainty was an English race-built galleon that began to be built in 1588. The original name was Repentance, but this was soon changed. It participated in some naval engagements in the Anglo-Spanish War (1585–1604). In 1593 it sailed from England under Richard Hawkins to navigate the Pacific Ocean and circumnavigate the world, but was captured the following year by the Spaniards when it was sailing off the coast of what is now Ecuador. It was commissioned by the Spaniards as Nuestra Señora de la Visitación, serving in the South Pacific for several years.
