And after arriving safely in Martinique, Savin said, “It was an exhilarating voyage but also quite risky.”
As a former military paratrooper, Savin is used to harsh conditions, though spending four months in a nine-foot-long barrel is tough to prepare for. The barrel, with 64-square-foot of living space, contained a bed, kitchen, storage, and a small porthole in the bottom through which Savin can watch the passing fish. The barrel was designed to withstand crashing waves and attacks by marine creatures, and apparently, it did its job.
Throughout the journey, Savin sustained himself on a diet of freeze-dried food, freshly caught fish, and supplies offered by other ships he passed on his voyage.
If you want a truly detailed first-hand account of Savin’s voyage, you’ll be happy to learn that he began writing a book about the experience during his long days at sea. He hopes to publish it later this year.
