(1) Any county may impose an annual registration fee on vessels registered, operated, used, or stored on the waters of this state within its jurisdiction. This fee shall be 50 percent of the applicable state registration fee as provided in s. 328.72(1) and not the reduced vessel registration fee specified in s. 328.72(18). However, the first $1 of every registration imposed under this subsection shall be remitted to the state for deposit in the Save the Manatee Trust Fund created within the Fish and Wildlife Conservation Commission, and shall be used only for the purposes specified in s. 379.2431(4). All other moneys received from such fee shall be expended for the patrol, regulation, and maintenance of the lakes, rivers, and waters and for other boating-related activities of such municipality or county. A municipality that was imposing a registration fee before April 1, 1984, may continue to levy such fee, notwithstanding the provisions of this section. (2) Any county which imposes an annual registration fee may establish, by interlocal agreement with one or more of the municipalities located in the county, a distribution formula for dividing the proceeds of the fee or for use of the funds for boating-related projects located within the county or the municipality or municipalities, or the county and the municipality or municipalities.
