I never knew what this actually was until I just read the entire Wikipedia article, and I came away from it thinking this is a really unimpressive / crummy / mediocre thing to be calling an expedition. Some dudes floating on a raft with radios to prove a point just seems a ways off the exploits of actual competent explorers of which there are many.
Like if I decided to prove a point by traveling from Brisbane to Sydney on a tuk-tuk with an iPhone I don’t think that would be worthy of a prize. Even Jeremy Clarkson crossing nations in Africa in a Lancia sounds more impressive, the Kon-Tiki raft is far better made than a Beta coupe and significantly more water resistant.
