Jose Salvador Alvarenga was fishing off the coast of Mexico in late 2012 when a robust storm despatched his boat adrift. Marshall Islanders discovered the battered vessel almost 16 months later, caught on a reef—with Alvarenga nonetheless alive inside. Rainwater and a eating regimen of fish and turtle sustained him (or so he advised the press). Curious how DIY savvy might stave off catastrophe, we requested Frances and Michael Howorth, authors of The Sea Survival Handbook, for recommendation.
Shelter: Don’t discard any clothes; a number of layers can preserve you heat throughout chilly nights. On sizzling days, drape or prop garments overhead.
Water: By no means drink seawater. When you’ve got a raincoat, detach the hood and use it to catch and retailer rainwater. Plastic luggage and rain boots additionally make wonderful containers. All the time rinse them with the primary raindrops to clean away salt from sea spray.
Meals: A ship’s shadow can entice fish. To catch them, string jewellery right into a lure. (Items from a smartphone can work too.) Shoelaces or unraveled sock threads can function fishing line. Save any uneaten bits for bait.
Rescue: Calm down and discover acquainted shapes in clouds to ease boredom—and preserve a watch out for planes and ships. For those who spot one, use a pocket mirror or a smartphone display screen to replicate daylight. The sign may be seen as much as 10 miles away on a sunny day.
