The Okeanos Foundation is stationed across the Pacific mostly in remote islands where big freight companies don't usually operate.
Commander and master navigator Peia Patai says they're pushing for traditional Pacific navigation methods to be revived and raising climate change awareness.
"Our ways of propelling these vessels are sustainable," he says. "Using the sun, the wind and we have engines fitted on that use coconut oil that have been created by people on the islands so at the same time we're conscious of the ocean's health."
