This system of three web-based models allows users to estimate boater spending and the associated economic impacts in terms of jobs, sales, income, and value added associated with the ownership (e.g., craft spending) and use (e.g., trip spending) of different sizes and types of recreational boats in Florida. The data used to develop the models came from the Florida Boating Access Inventory and Economic Study, which completed approximately 30,000 surveys of registered Florida boat owners. The study was commissioned by the Florida Fish and Wildlife Conservation Commission (FFWCC) with funding provided by the U.S. Fish and Wildlife Service, Lee County, Florida, and FFWCC. Information was collected about 17,300 Florida boating trips and the annual craft spending (e.g., storage, insurance, boat payments) of almost 3,800 boat owners. Users can estimate the economic impacts for: (1) boats registered in Florida counties and regions, (2) Florida marinas, and (3) boat launch (access) sites.
