The Adlard Coles Nautical Quiz Book is perfect for seafaring quizzers. It's divided into six nautically-flavoured categories, covering 1,000 questions. Categories range from Geography, Famous people and History to Culture, Science and Trivia. Each round is graded as easy (Able Seaman), medium (Midshipman) or tough (Hard Tack). A random sprinkling of nautical 'did-you-knows' adds a little salt to the mix and there's a quick-fire section at the end to keep everyone on their toes.
