I never saw the movie, but I can see why studio execs read this book and pounced on the concept. Junger’s writing style is very similar to a screenplay– laying out the main characters so that we have empathy for them, conjuring up the storm (3 converging storms that turn into mega storm), man vs. the elements.
A ragtag bunch of sailors leave Glouchester, MA late in the swordfish season and head out to find a major catch off the coast of Newfoundland. Later in the book, other boats enter the story so that they can be rescued. US Coast Guard rescue missions fly out to rescue various boats, and end up needing to ditch their helicopter and get rescued themselves.
