The Esmeralda is a steel-hulled, four-masted barquentine serving as a prominent training vessel of the Chilean Navy. Launched on May 12, 1953, in Cádiz, Spain, she was originally intended to be Spain’s national training ship. Construction faced significant setbacks after a catastrophic explosion in 1947 damaged the ship and nearly bankrupted the shipyard. Subsequently, in 1950, Chile and Spain negotiated a debt repayment arrangement, with Spain transferring ownership of the incomplete vessel to Chile in 1951. The ship was finally completed and delivered to Chile on June 15, 1954, under the command of Captain Horacio Cornejo Tagle. Her rigging was modified in the 1970s from a four-masted topsail schooner to a barquentine, replacing the fore gaffsail with two main staysails, increasing her sail plan to five staysails, three gaff topsails, six jibs, three gaff sails, and four square sails, totaling 21 sails. This rigging allows her to perform a variety of sailing maneuvers and demonstrates her versatility as a training vessel. Esmeralda’s maiden voyage took her to the Canary Islands, then to New Orleans, where a distillation plant was installed, before transiting the Panama Canal to arrive at her home port, Valparaíso, on September 1, 1954. Since her commissioning, she has circumnavigated the globe, visiting over 300 ports worldwide and acting as a floating Chilean embassy. Notable appearances include participation in Operation Sail in New York City in 1964, 1976, and 1986, as well as the Osaka World Sail in 1983. She has won the Cutty Sark Trophy in 1982 and 1990 during international regattas. Throughout her history, Esmeralda has been both celebrated for her maritime achievements and marred by controversy due to her use as a detention ship during Pinochet’s regime, where reports describe her as a site of political imprisonment and torture. Her international voyages often sparked protests, reflecting her complex legacy as both a symbol of national pride and a reminder of darker historical chapters.
