Sam Warwick first learned to dive with the British Sub-Aqua Club in the early 1990s, has logged over 1,000 dives around the world and is passionate about exploring and researching shipwrecks. Sam has always had a personal interest in Cunard history due to family connections with the line, since both his father and grandfather were Cunard Line commodores. These combined diving and Cunard interests led to the publication of Shipwrecks of the Cunard Line (2012) with co-author Mike Roussel. This was followed by The Union-Castle Line – Sailing Like Clockwork (2015) and Shipwrecks of the P&O Line (2017). The latest book is a collaboration with his father on the 4th edition of QE2: The Cunard Line Flagship, Queen Elizabeth 2, published April 2019.
