The Robertsons' boat was attacked by killer whales and started to sink fast

Douglas was 16 years old when his parents sold the family farm in England and took him and his three siblings on a sailing trip around the world. It was the adventure of a lifetime. But in 1972 while en route to New Zealand, their yacht was hit by a pod of orcas and they started to sink fast. Weeks from safety and with no way to send for help, Douglas and his family would have to try and find a way to survive.
