The following are exempt from the required permit:
•Operators of most out-of-state watercraft and floatplanes, as well as commercial transporters of watercraft, are now required to purchase an Aquatic Invasive Species (AIS) Prevention Permit from the Washington Department of Fish & Wildlife (WDFW). The $24 permit ($20 permit + $4 fee) can be purchased online or at any WDFW license sales location throughout the state. Watercraft registered in the State of Washington automatically pay an annual fee as part of their registration and therefore do not need to separately purchase a permit; a valid Washington State registration sticker is proof of payment.
•Vessels registered in Washington (recreational vessels with a valid WA State registration);
•Small watercraft (from Washington or out-of-state) that do not require state or country registration such as canoes and kayaks;
•Watercraft registered as “tenders” to larger boats;
•Vessels registered in Idaho or Oregon, when being used in shared state waters (private recreational unless otherwise registered);
•S. and foreign commercial vessels (with valid commercial marine documentation as a vessel of the U.S. or a foreign country);
•Private and commercial vessels being transported overland by a commercial transporter (a permit is required by the commercial transporter only);
•Military vessels owned by the U.S. government; and
•Vessels owned by any federal, tribal, state, or local government agency or other public entities, and used primarily for governmental purposes.
