Vessel Type Description

This wreck is a twin-screw vessel with a wooden Hull, indicative of shipbuilding practices from the late 19th to early 20th century. Twin-screw vessels were valued for their enhanced maneuverability and were employed in various capacities, including transport, fishing, and service operations. The wooden Hull suggests an older vessel, likely predating the widespread use of steel hulls.

History

The wreck’s history and identity remain unknown. Its wooden Hull and twin-screw configuration point to a vessel designed for versatility and control, common during the transitional period between wood and steel ship construction. Its current state suggests it has been submerged for many decades, with natural forces contributing to its deterioration.

The wreck lies at a dangerously shallow depth of 1-2 feet, making it a significant hazard for surface navigation. Its proximity to the water’s surface increases the risk of collisions, particularly for small craft or vessels with shallow drafts. The site has been confirmed by divers, who have classified it as a navigational danger due to its deteriorated yet substantial structure.

Final Disposition

The wreck remains submerged and largely unstudied, posing a persistent navigational hazard. Its shallow depth and deteriorated condition necessitate further study to understand its structure and update nautical charts accordingly.

Located By & Date

The wreck was verified by divers at its current position (Latitude 45.661622N, Longitude 84.435058W). A full survey is recommended to document the wreck’s condition and update navigation advisories.

NOTMARs & Advisories

Mariners should refer to current Notices to Mariners (NOTMARs) for the latest advisories regarding this wreck. Due to its shallow depth, even slight changes in weather, water levels, or Visibility can increase its risk to surface vessels. Navigators in the area are urged to exercise extreme caution.

Conclusion

The unidentified twin-screw wooden vessel in Lake Huron is a critical navigation hazard due to its shallow depth and deteriorated state. While its history remains unclear, its classification as a dangerous submerged object highlights the need for further surveys and investigation. Mariners and divers operating in the vicinity should proceed cautiously and consult updated nautical charts and NOTMARs.
