SS Manasoo – A World-Class Deep Technical Wreck

Resting upright in 205 ft / 62 m of cold, clear water in Georgian Bay, the SS Manasoo is one of the most intact and haunting wrecks in the Great Lakes.

Originally built in 1888 as the Macassa, she served as a passenger vessel before being rebuilt and renamed Manasoo in 1928. That same year, she departed Manitoulin Island carrying crew, passengers, a load of cattle, and a brand-new Chevrolet coupe. Caught in a violent storm near Griffith Island, the ship developed a severe list and capsized in the early hours of September 15. Only five survived.

Lost for nearly 90 years, the wreck was discovered in 2018—remarkably preserved and sitting upright on the lakebed.

Today, the Manasoo offers an extraordinary technical dive:

• Depth: 205 ft / 62 m

Divers are met with an unforgettable scene. The wheelhouse remains intact, complete with helm, compass, and a clock still hanging on the wall. Midship stairs lead toward preserved staterooms, while the engine room and deck structures remain clearly defined.

One of the most iconic features is Wallace’s 1927 Chevrolet coupe, still sitting on the cargo deck with its license plate in place. Scattered artifacts—including dishes, tools, and personal belongings—create a powerful sense of suspended time. The presence of cattle remains adds a sobering reminder of the ship’s final moments.

Penetration is possible but demanding. Interiors are fragile, silty, and hazardous, requiring advanced wreck training, discipline, and precise buoyancy control.

This is a serious expedition-level dive in a remote location, requiring full self-sufficiency, redundant systems, and proper gas planning.

For qualified technical divers, the SS Manasoo is more than a dive—it’s a rare opportunity to explore a perfectly preserved moment in Great Lakes history.

J.H. Jones

Built in 1888 in Goderich, the J.H. Jones was a 107-foot steamer originally designed as a fishing tug, servicing remote communities along the eastern shore of the Bruce Peninsula and Manitoulin Island. For years, she was a vital lifeline—transporting supplies, equipment, and supporting the region’s thriving fishing industry.

On November 22, 1906, the J.H. Jones departed Owen Sound on what would be her final voyage of the season. Loaded with kerosene and essential provisions, she was bound for Lion’s Head, Tobermory, and the North Shore to retrieve fish boxes from isolated stations. Battling severe weather, the vessel was last seen off Cape Croker by a lighthouse keeper who noted she was struggling in the worsening conditions. She never reached her destination.

Lost beneath the waters of southern Georgian Bay for over a century, the wreck was finally discovered on July 1, 2018, in approximately 160 feet of water near Lion’s Head. Today, the J.H. Jones rests largely intact on the lakebed. Her toppled smokestack, exposed interior, and visible steam engine components offer a striking glimpse into Great Lakes maritime history.

Now a protected marine archaeological site under the Ontario Heritage Act, the J.H. Jones is a compelling deep dive for experienced technical divers—combining historical intrigue with an impressively preserved wreck in the cold, clear waters of Georgian Bay.

Jane Miller

Built in 1879, The Jane Miller was a 78-foot passenger and cargo steamer. Build short with a high profile, it made the ship roll heavily in storms and was difficult to handle. The night she disappeared, there was a blizzard that increased quickly and she sank. When the snow cleared after a few minutes, the ship was gone and no one saw what happened. 

The ship was discovered on July 27, 2017, upright and flat on the bottom. The cargo deck and the hull were intact.
