United States lightship Swiftsure (LV-83)

Light Vessel Number 83 (LV-83) Swiftsure is a lightship and museum ship owned by Northwest Seaport in Seattle, Washington. Launched in 1904 at Camden, New Jersey and in active service until 1960 after serving on all five of the American west coast's lightship stations, it is the oldest surviving lightship in the United States, the only one still fitted with its original steam engine, and the last lightship with wooden decks.
