Description

The wreck with CRD 4380 is an unidentified, submerged vessel located in Lake Superior, presenting a navigational hazard. Originally charted as a visible wreck at a scale of 1:10,000, it has since been reclassified as a submerged wreck. The wreck is elongated, measuring roughly 10 meters in length. Despite this reclassification, its status remains “not specifically investigated.”

History and Survey Information

The initial charting of the wreck placed it at 46-29-03.0N and 84-17-33.5W. Updates moved the identified coordinates to 46.484186 and -84.292675, yet the wreck was never specifically surveyed or visually confirmed.

Efforts to confirm or disprove the wreck’s existence included:

1.Survey Requirements:

•Bothttps://shotlinediving.com/wp-content/uploads/52895851813_b64678c0f7_c.jpg drag or diver investigation within a 50-meter radius to locate the wreck.

•Verification of least depth or elevation and precise positioning, if found.

2.Disproval:

•Documentation of salvage operations, if available, could refute the wreck’s presence.

Despite these outlined procedures, the wreck’s existence remains unverified as no specific investigation has occurred to date.

Current Status

The wreck remains:

•Classified as submerged and dangerous to navigation.

•Uninvestigated and unmarked on navigation charts, pending future surveys.

Recommendations for Survey and Navigation

•Investigation Methods: Utilize a bothttps://shotlinediving.com/wp-content/uploads/52895851813_b64678c0f7_c.jpg drag or deploy divers to survey a 50-meter radius around the reported coordinates.

•Salvage Documentation: If previously removed, evidence should be submitted to disprove the wreck’s existence.

•Navigational Advisories: Mariners are advised to exercise caution in the area.

NOTMARs & Advisories

No specific Notice to Mariners (NOTMARs) or charted warnings are associated with this wreck, but its hazardous nature is implied by its classification.
