How to register your boat

To title and register your boat in Washington:

1. Gather all the required documentation

Gather all of the following:

Vessel Title Application

Complete the Vessel Title Application on white paper. If you bought the boat at a dealership, they'll complete this form for you.

Your current out-of-state registration

If your boat isn't currently registered in another jurisdiction, please contact a vehicle and boat licensing office for instructions.

The out-of-state title

  • If there is a lienholder, bring a photocopy of the out-of-state title
  • If you don't have your out-of-state title, contact a vehicle and boat licensing office for instructions

Proof you paid sales tax on the boat

If you don't have proof that you paid sales tax when you purchased it, you may need to pay use tax when titling/registering your boat.

Proof of insurance (if necessary)

If your boat is more than 35 feet long and more than 40 years old, you must present proof of marine insurance when you transfer the title into your name or register it for the first time. You only have to do this once.

You may provide more than one policy to meet all of the following requirements. The insurance policy (or policies) must:

  • Be for at least a 12 month term from the time the boat changed ownership
  • Include $300,000 or more basic coverage
  • Include a provision for removing the boat if it sinks or causes pollution

Contact a vehicle and boat licensing office if you have questions about whether your policy meets the requirements.

The payment/fee

Bring a check or money order payable to the Department of Licensing. Some vehicle licensing offices may take card payments, but many do not. Check with your local vehicle licensing office for details.  Calculate your boat registration fees.

2. Submit your paperwork

You can submit your paperwork and the required fees in person at a vehicle and boat licensing office or by mail.

3. Properly display your decals and registration

When you've registered your boat, you'll get your registration and a set of decals with the assigned registration number (WN#). You'll also get Vessel Registration Number Instructions showing how to properly display the registration number and decals on your boat.

If you register by mail, you'll get them in the mail. If you register at an office, the licensing agent will give them to you before you leave.
