VESSEL TYPE DESCRIPTION

The wreck at this site remains unidentified, and the type of vessel is unknown. Given its extremely shallow least depth (4 feet), it poses a considerable hazard to surface navigation. No additional identifying features or construction details are available from the records. It may represent a wooden or steel vessel, potentially from the late 19th or early 20th century, though this is speculative.

HISTORY

Discovery and Initial Documentation:

•First identified during survey H9782/78.

•Verified by divers to have a least depth of 4 feet, confirming its classification as a dangerous hazard.

Unknown History:

•No details are available regarding the vessel’s identity, origin, or circumstances of its sinking.

•The wreck’s characteristics, such as size, structure, or potential cargo, have not been documented.

FINAL DISPOSITION

The wreck lies at the provided coordinates in Lake Huron, with a recorded least depth of 4 feet. This proximity to the surface makes it a significant risk to vessels, especially those with shallow drafts. The wreck’s exact condition is unknown, though its shallow depth suggests parts of the structure may still be relatively intact or even visible under certain conditions.

LOCATED BY & DATE

•Survey: H9782/78

•Verification: Divers confirmed least depth at 4 feet.

Further surveys and investigations are recommended to determine the wreck’s precise characteristics and condition.

NOTMARs & ADVISORIES

•Status: The wreck is classified as dangerous to surface navigation and should be avoided.

•Advisory: Mariners should consult updated Notices to Mariners (NOTMARs) for detailed information about the wreck and its location. Caution is advised, particularly under conditions of poor Visibility or rough waters.

CURRENT CONDITION & ACCESSIBILITY

•Condition: Unknown. The wreck’s structure may still be partially intact given its shallow depth but is likely deteriorating due to exposure and time.

•Accessibility: The wreck’s shallow depth makes it accessible for diving, though exploration may be limited by navigational hazards and poor Visibility in the area.

CONCLUSION

The unidentified wreck at Latitude 45.716000N, Longitude -84.573194W in Lake Huron represents a significant hazard to navigation due to its shallow depth and proximity to the surface. The lack of identifying details underscores the need for further investigation to understand its history and potential impact on maritime safety. Mariners should proceed with caution in the area, ensuring they reference the latest NOTMARs and navigational data.
