The Development of Rowing Equipment By Bill Miller This page contains information about the development of rowing equipment beginning about the end of the 18th century.
Christopher Smith contributed to the world of powerboat racing when he designed a hydroplane-stepped hull that led to a series of specialty race boats built by the Smith-Ryan Boat & Exchange Company. Smith also designed the Miss Minneapolis, which broke the 60-mile-per-hour speed barrier in 1916 â the first boat to do so. Eventually beginning the Chris-Craft company in 1922, Smith was the first to apply the concept of mass-production to boat building. Today, Chris-Craft is still a household name, and is to the powerboat industry what Ford is to the automobile industry.
