The lineage of Martin and the flying boat can be traced back to the PBM-4 of 1941, the Navy's last flying boat and the end of a long era of seaplanes. This book covers the complete history of the Martin P5M Marlin aircraft development, construction, systems, squadron, interior, exterior weapons, and stores. It includes Marlin losses and casualties, photos of the catwalks, and some of the hazards of working on a seaplane over the water. There are also sections on the US Coast Guard, French usage, and a modelers guide.
