Bulk carrier troubled on St. Mary's River

Sun Aug 03 17:55:00 CEST 2025 Timsen

On Aug 3, 2025, the "Robert S. Pierson", which has been sailing downstream on the St. Marys River en route from Sault Ste. Mrie to Saginaw at only four knots since leaving the Soo Locks in Sault Ste. Marie, has anchored at the exact spot where the stricken "Presque Isle" was just a few hours ago. The ship was being escorted or towed downstream by the "W. I. Scott Purvis" (IMO: 5264819) heading for Saginaw. The "Presque Isle" is likely docked at Donjon Shipbuilding & Repair in Erie, PA, for repairs. The cause was a grounding on the morning of July 30 at Johnson Point on Neebish Island.
