It is a 175-foot 'poolboat' owned by the State of Ohio and open to visitors.","why_significant":"The boat was built when steamboat construction was shifting from wood to steel, yet it keeps many features of nineteenth-century wooden river steamers. It is described as one of the last steam sternwheelers to work the inland waterways. It is significant in the areas of industry, commerce and transportation.","narrative":"Moored on the Muskingum River at Marietta, the W. P. Snyder, Jr. is a coal-fired steam sternwheeler launched in 1918 as the W. H. Clingerman. She measures 175 feet long and 32.3 feet wide, with a 21-foot paddle wheel and two sets of compound engines producing 750 horsepower. Built as a 'poolboat' with the pilothouse set forward on the second deck, she could pass under low bridges on the Monongahela River, where she pushed coal barges from upstream mines and occasionally steel tows as far as Memphis. Later renamed J. L. Perry and A-1, she took her present name after Crucible Steel Company bought her in 1945. The company gave her to the State of Ohio in 1955, and she steamed to Marietta for the presentation. Built during the shift from wood to steel, she retains hog chains, a pilot wheel, bell signals and stateroom construction typical of earlier river steamers. She is one of the last of her kind and is open to visitors.","period_of_significance":"1918","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Owned by the State of Ohio, open to the public through The Ohio Historical Society, and described as complete in every detail; plans were underway to make it part of a new Ohio River Museum.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:10.452765-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/70000522.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/70000522/9dfd3e7a63-800.webp","url_1600":"https://nationalhistoricalregister.com/media/70000522/9dfd3e7a63-1600.webp","licence":"CC BY-SA 3.0","author":"J Clear (talk)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:W.P.SnyderJr.jpg\" rel=\"noopener\">J Clear (talk)</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:W.P.SnyderJr.jpg"},"district":{"nrhp_refnum":"01000903","name":"Marietta Historic District (Boundary Increase)","url":"https://nationalhistoricalregister.com/districts/ohio/marietta-historic-district-boundary-increase-01000903/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71991933","wikipedia":"https://en.wikipedia.org/wiki/W._P._Snyder_Jr._(towboat)","wikidata":"https://www.wikidata.org/wiki/Q7945874"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/washington-county/w-p-snyder-jr-steamboat-70000522/"}
