What to know

Lightship No. 83 Swiftsure is a maritime marvel moored at the Historic Ships Wharf in Lake Union Park. Built in 1904 in Camden, New Jersey, for a cost of $90,000, this 129-foot vessel served as a floating lighthouse in locations where permanent construction was impractical. It is distinguished as the oldest lightship in the country and remains the only one to retain its original steam engine. Throughout its operational life, the ship assumed the names of the stations it served, including Blunts Reef, San Francisco, and Relief, before returning to the name Swiftsure. Much of its career was spent patrolling the California coast before it transitioned to its final decade of service and eventually joined the Northwest Seaport museum fleet in 1966. Recognized for its immense historical value, the vessel was listed on the Washington State Heritage Register and designated a National Historic Landmark in 1989. Today, it is operated by Northwest Seaport, a nonprofit dedicated to preserving the maritime heritage of the Northwest Coast and Puget Sound. Visitors are invited to climb aboard and roam the vessel to experience the living history of early 20th-century navigation. The ship serves as a hands-on venue for educational programs, stewardship activities, and public tours, offering a rare glimpse into the isolated lives of lightship crews.
