Navigation Advisory

Due to its categorization as “submerged, dangerous to surface navigation,” the wreck poses a potential hazard to vessels in the area. Mariners should exercise caution when navigating near the identified coordinates to avoid collisions or damage.

Current Condition & Accessibility

The small size of the vessel and its shallow depth make it easily accessible for divers or survey equipment. However, the low GP quality suggests that its precise location may require additional verification using sonar or other detection methods.

Recommendations

• Survey: Conduct a sonar or visual survey to verify the wreck’s current position and state.

• Marking: Install a buoy or marker at the site to warn mariners of the hazard.

• Historical Research: Further investigation into local records might uncover the origin and purpose of the vessel.
