La Balsa

La Balsa was the name of a 1970 expedition led by Spaniard Vital Alsar to sail a Balsa raft from South America to Australia across the Pacific Ocean.

The 8,600 mile voyage was, at the time, the longest in known history, only eclipsed by the 1973 Las Balsas expedition, again led by Alsar.

The expedition lasted 160 days, starting in Ecuador on May 29, 1970, and ended at Mooloolaba in Australia on November 5, 1970.
