Wreck Location Map
Vessel Type
The Unidentified D36 is believed to be a schooner or small sailing vessel, based on its hull structure and visible rigging remains. Schooners were a common type on the Great Lakes in the late 19th and early 20th centuries, prized for their versatility in transporting coal, lumber, grain, and manufactured goods. The design suggests it worked as a commercial carrier supporting regional trade.
Description
Discovered in 2021 by a NOAA side-scan sonar and ROV survey, the Unidentified D36 rests in about 55 metres (180 feet) of water off Oswego. Although its name and registry have not been confirmed, its hull style, rigging elements, and cargo layout strongly point to a schooner of the type heavily employed between the 1870s and early 1900s.
These vessels were vital to the commerce of ports like Oswego, serving as the backbone of grain, lumber, and industrial cargo routes that fuelled regional growth. Schooners, while efficient and robust, were prone to losses from sudden storms, collisions, or shifting cargo. Given its relatively intact structure, the D36 may have foundered during a storm or possibly due to a collision.
Today, the site is of high archaeological and historical interest. Its cargo holds, deck features, and rigging hardware all appear consistent with a working schooner of its era. Surveys note some deterioration from long-term submersion but generally stable preservation at depth.
History
The vessel is considered fairly intact on the lakebed. No evidence of salvage has been recorded. The cause of sinking remains undetermined, though severe weather or collision are likely.
Significant Incidents
- Discovered in 2021 by NOAA.
- Located near Oswego, New York.
Final Disposition
The vessel is considered fairly intact on the lakebed. No evidence of salvage has been recorded. The cause of sinking remains undetermined, though severe weather or collision are likely.
Current Condition & Accessibility
The D36 lies upright and largely intact, with some collapse of upper structures typical of wooden schooners after prolonged submersion. Its depth makes it suitable only for technical or advanced divers using trimix or rebreather systems, and further archaeological mapping is recommended to fully record the site.

The Unidentified D36 is a valuable discovery illustrating the working schooners that defined Great Lakes shipping during a formative era. It serves as a reminder of the scale of maritime commerce and the risks sailors faced on Lake Ontario. Continued research may eventually identify this ship, unlocking another piece of the lake’s complex heritage.
