Requirements for vessel registration vary from state to state. In Washington, you must have a Washington title, current registration certificate, and current registration decals to operate or moor a vessel. Exceptions to registration and titling are:
- Vessels that are not propelled by a motor (canoes, kayaks, etc.) and sailboats under 16 feet in length without a motor.
- Vessels that are less than 16 feet in length and have a motor of 10 horsepower or less and are used on non-federal waters only. All motorboats of any size or horsepower that are used on waters under federal jurisdiction must be registered.
- Properly registered vessels owned by residents of another state or country that use Washington waters for 60 days or less.
