Description
SS Pere Marquette 18 was a steel-hulled, steam-propelled car Ferry designed to transport rail freight and passengers across Lake Michigan. She featured two triple-expansion steam engines powered by six Scotch boilers and drove twin screws. Her design included four railroad tracks on the main Deck, accommodations for roughly 30 railcars, and staterooms for passengers. During summer seasons (1909–1910), she was temporarily refitted as an excursion Steamer.
History
Launched on 16 August 1902 as Hull No. 412 by American Ship Building Co., the vessel served primarily between Ludington, MI and ports in Wisconsin, including Milwaukee, Manitowoc, and Kewaunee. Her 1909 and 1910 summer seasons were spent as a passenger excursion vessel operating from Chicago to Waukegan. In September 1910, following re-inspection, she resumed Ferry service.
Final Dispositions
Pere Marquette 18 departed Ludington late on 8 September 1910 carrying 29 loaded railcars and 62 people. Around 3:30 AM, water was discovered flooding the Stern’s crew quarters compartment (“flicker”). Pumps failed to keep pace, and the crew began jettisoning railcars. At 5:00 AM, the wireless operator sent a CQD message received by the Pere Marquette 17, which responded immediately. Despite rescue efforts, the vessel sank Stern-first by 7:30 AM after a suspected internal air pressure explosion. Twenty-seven were lost, including the captain and all officers.
Located By & Date Found
On 23 July 2020, wreck hunters Jerry Eliason and Ken Merryman located the wreck using side-scan sonar and confirmed the identity with a drop camera. The wreck lies in 500 ft (152 m) of water, 25 miles east of Sheboygan, WI. The bow is raised, the decks are collapsed, and the pilothouse lies on the Stern.
NOTMARs & Advisories
None noted. The wreck is not a navigational hazard.
