Plastiki, a 60-foot sailboat largely constructed from 12,500 recycled plastic bottles, docked in Sydney Harbor today after four months crossing the Pacific Ocean on a journey meant to raise awareness about the perils of plastic waste.
The crew started out from San Francisco in March and traveled 8,000 nautical miles.
"This is the hardest part of the journey so far - getting it in!" expedition leader David de Rothschild yelled from the boat as the crew struggled to maneuver the notoriously tough-to-steer vessel into port outside the Australian National Maritime Museum, according to media reports.
"It has been an extraordinary adventure," he said.
De Rothschild, 31, said the idea for the journey came to him after he read a United Nations report in 2006 that said pollution - and particularly plastic waste - was seriously threatening the world's oceans.
