Travel writer Redmond O’Hanlon climbed aboard a deep-sea trawler hoping to ride headlong into a Force 12 hurricane. In the two weeks he spent on the Norlantean, he battled sea-sickness, sleep deprivation and ridicule from the ship’s crew, who thought him mad for even volunteering to sample their way of life. In the end, O’Hanlon got his story and his storm. He recounts the claustrophobic and very dangerous life of a trawlerman in his new book, “Trawler: A Journey Through the North Atlantic.”
