Steven Callahan

In the making of the 2012 movie Life of Pi, director Ang Lee asked Callahan to be a consultant on living aboard a life raft. Ang Lee told Callahan, "I want to make the ocean a real character in this movie". Callahan made lures and other tools seen in the movie.

Callahan departed Newport, Rhode Island, United States, in 1981 on the Napoleon Solo, a 6.5-meter (21.3-foot) sloop he designed and built himself, single-handedly sailed the boat to Bermuda, and continued the voyage to England with friend Chris Latchem. He had left Cornwall that fall, bound for Antigua as part of the Mini Transat 6.50 single-handed sailing race from Penzance, England, but dropped out of the race in La Coruña, Spain. Bad weather had sunk several boats in the fleet and damaged many others including Napoleon Solo. Callahan made repairs and continued voyaging down the coast of Spain and Portugal, out to Madeira and the Canaries. He departed El Hierro in the Canary Islands on January 29, 1982, still headed for Antigua. In a growing gale, seven days out, his vessel was badly holed by an unknown object during a night storm, and became swamped, although it did not sink outright due to watertight compartments Callahan had designed into the boat. In his book, Callahan writes that he suspects the damage occurred from a collision with a whale.

On the eve of April 20, 1982, he spotted lights on the island of Marie Galante, south east of Guadeloupe. The next day, on Callahan's 76th day afloat in the raft, fishermen picked him up just offshore, drawn to him by birds hovering over the raft, which were attracted by the ecosystem that had developed around it. During the ordeal, he faced sharks, raft punctures, equipment deterioration, physical deterioration, and mental stress. Having lost a third of his weight and being covered with scores of saltwater sores, he was taken to a local hospital for an afternoon, but left that evening and spent the following weeks recovering on the island and while hitchhiking on boats up through the West Indies.

Callahan holds a university degree in Philosophy. A naval architect by training, Callahan has designed and built boats, taught design, lived aboard, raced, and cruised boats of all kinds. Since the 1980s, he has also written widely for the yachting press worldwide, has been a contributing editor to Sail and Sailor magazines, senior editor of Cruising World, has authored Adrift and Capsized, the story of four men who drifted for four months on an overturned, half-flooded boat. He has also lectured widely and contributed to a number of other books on design, seamanship, and survival.

Steven Callahan (born 1952) is an American author, naval architect, inventor, and sailor. In 1981, he survived for 76 days adrift on the Atlantic Ocean in a liferaft.
