In 1971 English dairy farmer Dougal Robertson and wife Lyn sold their farm to fund a sailing voyage around the world with their four children (including 9-year-old twins). They made it to the Galapagos in 17 months, dropping one daughter off at port and picking up a Welsh hitchhiker along the way, when their ship was destroyed by orcas. They survived in a 10-foot-long dinghy and an inflatable lifeboat for 38 days until rescued by a Japanese fishing vessel.
