VESSEL TYPE DESCRIPTION #
The wreck described in record number 4688 remains unidentified, with no known details regarding the vessel’s type, size, or purpose. Given its classification as “dangerous to surface navigation,” the wreck may present a significant hazard, particularly due to its shallow depth, possibly being at or near the water’s surface. The lack of specific identification adds an element of uncertainty and risk to mariners navigating the area.
HISTORY #
The history of this submerged wreck is sparse and unclear, with the source of the initial report unknown. The wreck was charted in its approximate position based on historical data, but the accuracy of the coordinates is noted as “Low.” This suggests that the reported position may not be entirely reliable, which further complicates the situation for vessels operating in the area.
The charting was done using information scaled from chart 14863 at a scale of 1:120,000. The wreck’s presence has not been definitively confirmed, which necessitates a thorough survey to verify its existence and to assess the potential hazard it poses to surface navigation. The specifics of how or when the vessel sank remain undocumented, leaving much about this wreck shrouded in mystery.
FINAL DISPOSITION #
As of the latest available information, the wreck remains submerged and is considered dangerous to surface navigation. Due to the “Low” accuracy of its reported position, a full survey, including bottom drag within a 0.5 nautical mile radius, is required to verify or disprove the wreck’s presence. The survey’s findings will determine whether additional actions, such as removal or further marking, are necessary.
LOCATED BY & DATE #
The wreck was initially recorded and charted based on information from an unknown source. The charting was done at a scale of 1:120,000, with the coordinates scaled accordingly. The assignment “S-X927-HFP-87” was given for the necessary survey, indicating that a survey team should verify the wreck’s position and condition.
NOTMARs & ADVISORIES #
Given the classification of this wreck as “dangerous to surface navigation,” mariners should exercise caution when operating near the reported coordinates. The low quality of the geographical position suggests that the wreck could be slightly off from the provided location, increasing the risk for vessels. Local Notice to Mariners (LNM) advisories may have been issued, and these should be consulted by mariners to ensure safe navigation.

CONCLUSION #
The unknown wreck described in record 4688 poses a potential hazard to navigation in Lake Huron, particularly due to its shallow depth and the low accuracy of its reported coordinates. Mariners should be vigilant when navigating near the provided location, as the wreck could pose a serious risk to surface vessels. A full survey is necessary to confirm the wreck’s presence and to take appropriate measures to mitigate the danger it presents.
