A crew of sailors is two weeks into their high-seas, old-school (no GPS) and totally dangerous 10,000 mile journey across the Pacific, from New Zealand to Easter Island.

Look how far that is on a map.

The 20 Maori sea men and women, in two double-hulled “waka,” are guided northeast only by the stars, currents, sun and moon according to the Waka Tapu‘s website. The boats are powered by the currents, wind and oars.

Currently, the Waka Tapu drift somewhere in… well, nobody knows where exactly they are. The boats left Auckland on August 17, but the mission carries no “instrumental-navigation techniques.”

The captain tells Auckland Now via satellite phone the boats are 581 nautical miles “along the courseline.”

Eventually, hopefully in October, they’ll reach Rapanui, also known as Easter Island. Rapanui is known as a very expensive vacation destination and an archetype for anthropogenic human extinction.

The boats, called Te Aurere and Ngahiraka Mai Tawhiti, carry 20 men and women aboard, including two medics, a fisherwoman and captains Jack Thatcher and Stanley Conrad.
