Phillip Kunz and William G. Holder’s Prop Riders: 60 Years of Racing Hydroplanes traces the evolution of racing boats that brought automotive V-8 power to the water. The illustrated history covers hull design, engines, drivers, racecourses, safety, and the restoration of vintage hydroplanes. An appendix lists postwar record holders alongside their boats and engines, making the book a useful reference for boat racing fans and hot rodders alike.
