The purpose of this legislation is to update and improve the Dingell-Johnson Sport Fish Restoration Act, focusing on enhancing sport fish restoration efforts and ensuring recreational boating safety. It aims to provide better funding and support for these activities, as well as to promote the use of alternative fuels in boating. Key provisions of the legislation include extending the timeline for annual appropriations related to sport fish restoration from 2026 to 2031. This change allows for more funding to be allocated over a longer period.
