I would go with this explanation. Also, that the oceans have been terribly overfished.
And, yes, I think the crew of KonTiki used freshly cut Balsa, which absorbed water over time and made the raft even slower. I also recall that they observed one of the first Whale Sharks seen by man.
EDIT: I WANNA GO!!!!!
