Wreck Location Map

Vessel Type

The wreck is identified as a “Twin Screw” vessel with a wooden hull. Twin-screw vessels are equipped with two propellers, allowing for better maneuverability and control compared to single-screw ships. These types of vessels were often used for a variety of purposes, including transport, fishing, and service operations. The fact that this wreck is made of wood suggests it may date back to the late 19th or early 20th century, when wooden hulls were still commonly used in shipbuilding.

Description

The exact history of this twin-screw vessel remains unknown, as it has not been positively identified. The wreck is made of wood and lies very close to the surface of Lake Huron, with a least depth of just 1-2 feet. Its shallow position and wooden construction indicate that it has likely been submerged for an extended period, with natural forces gradually reducing its structural integrity.

Divers have verified the wreck’s presence and condition, confirming its classification as a hazard to surface navigation. The wreck’s shallow depth makes it particularly dangerous for small craft and vessels with a shallow draft, which could easily collide with the remnants of the structure.

History

The wreck remains submerged in Lake Huron, with its twin-screw configuration and wooden hull still recognizable. The shallow depth, with parts of the wreck lying just 1-2 feet below the surface, poses a significant risk to surface navigation. The structure has deteriorated over time, but it is still substantial enough to present a hazard to vessels passing over or near the site.

Significant Incidents

• Verified by divers; classified as a hazard to surface navigation.
• Survey requirements listed as “FULL,” indicating the need for further investigation.

Final Disposition

The wreck’s position has been verified by divers and is located at Latitude 45.661622°N, Longitude 84.435058°W. The wreck remains submerged, and its condition underscores the need for caution in the area.

Current Condition & Accessibility

Mariners should consult current Notices to Mariners (NOTMARs) for advisories related to this wreck. Due to its extremely shallow depth and the potential for changes in the wreck’s condition, it is essential for vessels operating in the area to exercise caution. The wreck’s proximity to the water’s surface makes it a particular hazard, especially during times of low visibility or rough weather.

The unidentified twin-screw wooden vessel in Lake Huron presents a serious navigational hazard due to its extremely shallow depth and deteriorated condition. While the wreck remains largely unstudied, its classification as a dangerous submerged object underscores the need for caution in the area. Further surveys and investigations are recommended to provide a more complete understanding of the wreck’s current state and to update nautical charts as necessary.
