I read the Science Daily article about Professor Dorothy Hosler and her students' building of a raft to replicate those used in pre-Columbian Pacific trade with interest. (My interest was sparked by reading Charles Mann's excellent book, 1491: new revelations of the Americas before Columbus) I wanted to learn more--frankly, I wanted to see photos.
In the May 13, 2009 issue of MIT's Tech Talk are photos of the raft's test on the Charles River. (It's on the last page.)
The raft still has some more tests to undergo, but the article reports that so far it performed very well!
