The Infinity is a 120ft yacht which sails the world gathering crew members en route from various walks of life all across the world who are willing to volunteer their time, helping to run the yacht and projects whilst living and embracing the free spirited philosophy of the "Sea Tribe".
The purpose of the trips are to raise awareness of the climatic changes affecting the remoter communities of the Pacific islands. This is done through interacting with local communities to document aspects of their lives and culture or local perceptions on environmental issues.
Stace is meeting the crew in Samoa in November and she's looking for other volunteers to do it with her. See more info here:
