The Washington State Watercraft Passport is free and available for use by the public. The passport is primarily designed for Washington residents who regularly transport recreational watercraft in and out of the state, but is available to any boater. The passport can help boaters to keep track of the waters they've visited and aquatic invasive species (AIS) inspection stations they've stopped at.
