The Maritime Museum of San Diego sits on the North Harbor Drive waterfront, and its centrepiece alone is worth the stop. The Star of India, launched in 1863 on the Isle of Man, is the world's oldest active sailing ship. Named Euterpe after the Greek muse of music, she endured a mutiny on her first voyage, a cyclone on her second, and still managed to circumnavigate the globe 21 times. She arrived in San Diego in 1927 and still puts to sea, crewed by volunteers, at least once a year.

Alongside her sits the Berkeley, an 1898 steam ferry, and the San Salvador, a full-scale replica of the galleon Juan Rodríguez Cabrillo sailed into San Diego Bay in 1542. It is, in one compact stretch of waterfront, six centuries of seafaring in one view.

VoiceMap's self-guided audio tours trace San Diego's maritime identity from Cabrillo's first European landfall through the age of sail and into the age of steam. Each vessel in the fleet becomes a chapter in the city's longer story of the sea.
