The bill proposes the introduction of a new special license plate called "Nautical Northwest," which will be available for an initial fee of $40.00 and a renewal fee of $30.00. This plate will be added to the existing list of special license plates under RCW 46.17.220, and amendments will be made to RCW 46.18.200 and RCW 46.68.420 to incorporate the new plate and its associated fees. The funds collected from the sale of the Nautical Northwest plate will be dedicated to supporting the historic resources of Whidbey Island's maritime communities, thereby promoting local heritage and cultural significance.

Additionally, the bill outlines eligibility criteria for cities to receive construction funds for public tennis facilities, prioritizing the most populous eligible city without existing facilities that have at least four indoor tennis courts. Maintenance funds will also be prioritized for the first city that utilizes the construction funds. The bill specifies that at least 90 percent of funds from the Seattle Seahawks and Seattle Mariners special license plate accounts must be allocated to fellowships and youth services, respectively. It also defines "Nautical Northwest license plates" as special plates featuring a Northwest maritime scene, with the act set to take effect on November 1, 2025.
