The book is fictional, however, Richard Gordon, the author, was a ship's surgeon and anaesthetist resulting in a strong sense of realism being conveyed throughout. The introductory pages set the comedic tone for the remainder of the novel.

Central to this novel and themes of maritime adventure, mishaps, comedy, and emergency medicine. The ship's crew are diverse and there are various personality clashes which tend to become inflamed with rapidity, partly, because all on board are bordering on, or are alcoholic. On board the primary prescription is 'medical comforts' that is any liquor within arm's reach. The 'medical comforts' are imbued by both the patient and the doctor alike, for pain and then for the Dr's confidence. Confidence being a necessity given that most of the surgical equipment has been borrowed by light fingers to be sold or traded.

Richard Gordan is a master of making the scenes come to life, by using concise descriptions and the regular inclusion of dialogue.
