Fantastic book. Related to sailing as to "when it breaks, who's gonna fix it?" -- i.e. if you're 1000 miles from a well stocked chandelier, what ya gonna do?Also not exactly a sailing book is The Martian, recently turned into a movie.
Hard (not fantasy) science fiction, heavy on life support systems, math, etc.. Much better than the movie.
Also _very_well written. And it could be real. Even though the book is absolutely fantastic, the movie is pretty dang good. And really, isn't deep space travel highly analogous to long distance sail cruising?
