The Str. PORTLAND was built at Portland, Oregon, in 1947 as sternwheel towboat, steel hull, but wooden upper decks. Decommissioned in 1981, the Oregon Maritime Museum is using her since 1989 as a swimming museum, while she is still working and is under steam several times a year.
The Str. PORTLAND makes a 4-hour trip each month in the summer. It goes down through the Portland Oregon harbor to the meeting of the Willamette and Columbia River and returns to the waterfront in downtown Portland.
