Identification & Site Information

•Vessel Name: Unknown (Submerged Tug)

•Type: Tugboat

•Location:

•Latitude: 42-53-48N

•Longitude: 78-54-32W

•Last Known Survey: Hydrographic Survey H9841/79 (1979)

•Final Disposition: Submerged wreck, classified as a dangerous obstruction to navigation

Vessel Type Description

The wreck is identified as a submerged Tugboat. Tugboats are small but powerful vessels used for towing and maneuvering larger ships in ports, narrow channels, or hazardous areas. Known for their durability and utility, tugboats play a vital role in maritime operations. However, details about this specific Tugboat’s construction, dimensions, or operational history remain unknown.

History

The history of the submerged Tugboat is enigmatic, with minimal records detailing its origin or circumstances of sinking.

•1972: The wreck was noted to have shifted position.

•1973: Search efforts to locate the wreck were unsuccessful.

•1978: Aerial photography revealed a stranded wreck in the area, likely the same vessel.

•1979: A hydrographic survey (H9841/79) conducted with echo sounders failed to locate the wreck. Wire drag operations were deemed impossible due to strong currents, underwater grass, and an irregular bothttps://shotlinediving.com/wp-content/uploads/52895851813_b64678c0f7_c.jpg profile.

Despite its elusive nature, the wreck’s presence was deemed significant enough to be charted as a dangerous obstruction to navigation.

Final Disposition

The Tugboat is presumed to remain submerged near LAT 42-53-48N, LONG 78-54-32W. Its status as a navigational hazard is based on historical observations and aerial data. While its exact condition and location remain uncertain, it continues to pose a potential risk to vessels.

NOTMARs & Advisories

Mariners are advised to exercise caution near the coordinates due to the potential presence of a submerged wreck. Though efforts to locate the wreck during hydrographic surveys have been unsuccessful, it remains charted as a hazard based on historical data.

Located By & Date

•Initial Designation: Coast Pilot 6 marked it as a dangerous submerged wreck.

•1972: Observed to have shifted position.

•1973: Could not be located during searches.

•1978: Aerial photography revealed a stranded wreck in the vicinity.

•1979: Echo sounder survey (H9841/79) yielded no conclusive results.

Current Condition & Accessibility

The current state of the submerged Tugboat is unknown due to failed survey attempts. Challenges in the area include:

•Irregular Bothttps://shotlinediving.com/wp-content/uploads/52895851813_b64678c0f7_c.jpg Profile: Complicates accurate location.

•Underwater Grass: Impedes search and diving operations.

•Strong Currents: Increases risk for divers and survey equipment.

These factors make diving in the area hazardous. Extreme caution is recommended for any exploration attempts.
