Poon Lim on his raft, in a reconstruction for US Navy survival training

Poon at first kept himself alive by drinking the water and eating the food on the raft. After around 55 days, the food ran out, followed by the water supply fifteen days later.[9] After spending five days without water,[10] Poon resorted to fishing, catching seabirds, and collecting rainwater in a canvas life jacket covering. He could not swim well, and often tied a rope from the boat to his wrist in case he fell into the sea. He took a spring from the flashlight and made it into a fish hook, unravelled hemp rope to make a fishing line, and crushed pieces of hardtack to make bait. He dug a nail from the boards on the wooden raft to make a stronger fish hook. When he caught a small fish, he used it as bait to catch bigger fish. He improvised a knife from part of a pemmican can. The water tank had an iron key, which Poon also used as a tool. When gulls settled on his raft, he caught and killed them. He soaked their meat in seawater to salt it, then dried it on deck to make jerky.[11]

When Poon saw sharks, he caught one,[11] using the remnants of gulls he had caught as bait. Poon had braided his fishing line to double thickness, and had wrapped his hands in canvas to give them a little protection. The shark attacked him after he hauled it aboard the raft, so he used a water container to beat it to death. Poon cut it open and sucked the blood from its liver. This quenched his thirst, since it had not rained and he was out of water. He sliced off the fins and let them dry in the sun.[citation needed]

I had no idea the body could last that long with so little water, and to have the discipline to be playing the long game like that from the start is amazing.
