Vessel Type

The Edward E. Gillen was a steel-hulled harbor tug originally built as Erstus C. Knight in 1908. Initially steam-powered using a recycled engine from the tug Mary, she was converted to diesel in 1928 with a Winton 6-cylinder engine.

Description

Measuring 56.5 feet in length with a 15.3-foot beam, she operated in multiple Great Lakes ports throughout her 73-year career.

History

Originally serving the American Sand & Gravel Co. in Erie, PA, the vessel changed names and roles several times. Renamed Aubrey in 1917, she was later sold to American Construction Co. and then Merritt-Chapman Scott. Her 1964 renaming to Edward E. Gillen by the Milwaukee-based firm of the same name honored an earlier wooden tug lost in 1903. She was rebuilt in 1953 and remained active in local maritime work.

Her final assignment involved cable testing with the USCG icebreaker Westwind. A stern towline—against standard practice—was secured, and as the Westwind moved ahead, the tug submerged by the stern and capsized within minutes. All four crew were rescued.

Significant Incidents

  • Capsized and sank while engaged in cable tests with USCG Westwind.
  • A mismatch in power and improper towline placement contributed to the rapid sinking.

Final Disposition

Located shortly after sinking in June 1981, the site is now documented by Wisconsin Historical Society and 3DShipwrecks.org.
