Register a boat: Documented vessels

What is a documented vessel?

A documented vessel is a ship with a valid marine document issued by the United States Coast Guard. The federal government uses this document to register ships of 5 net tons or more for use in times of war. Documenting your ship gives you:

  • Firm evidence of nationality for international travel.
  • The right to engage in open trade between the states.
  • Access to a preferred mortgage for financing the vessel.

Registration requirements

Unless specifically exempt, you must meet all Washington state registration requirements when using a documented vessel on Washington waters. This means you must register your boat in Washington:

  • Within 60 days of moving to Washington with the vessel.
  • Within 15 days of buying the vessel, if bought it in another state and you live in Washington.
