In John R. Stoll, John C. Bergstrom, and Lonnie L. Jones' "Recreational  Boating and its Economic Impact on Texas" article, they assert that recreational boating as a whole is greatly influential on the Texas economy throughout the entire state of Texas. This recreational boating provided for "10270 man-years of employment" as well as "had a total output of over $610 million." They do this in order to provide evidence as to why the activity of recreational boating is so significant. This information was presented in a statistical manner to a well educated audience.
