Off the charts: how a Polynesian canoe inspired a renaissance in traditional seafaring

The Hklea's oceanic voyages, navigated by the stars, have led other Indigenous people to revive their own ancient traditions - and serve as a call to action on the climate

A double-hulled Polynesian sailing canoe glides up to a busy dock in San Diego, California. Hklea's two short wooden masts are dwarfed by the historic schooner that escorted the boat into the harbour. Dozens of small outrigger canoes trail in its wake, honouring the crew's arrival.

Once the docklines are secure, Hklea's 13 crew members put on ceremonial leis - floral garlands - and request permission from the local Indigenous tribe to come ashore. In response, 30 members of the Kumeyaay Nation sing and dance to welcome them to their native lands. Hundreds of onlookers snap photos before joining the festivities at a nearby park.
