American archaeologist and ocean sailor Gene Savoy has died aged 80. He sailed a reed raft, Kuviqu, in 1969 to prove that ancient Peruvian and Mexican civilisations could have traded with one another.

He later sailed round the world on a mahogany raft in a bid to prove how much further South Americans could have gone.

He wrote four books on exploring including Antisuyo: The Search for the Lost Cities of the Amazon and On the Trail of the Feathered Serpent.
