We’re excited to announce the latest addition to the growing archive at 3DShipwrecks.org — a detailed photogrammetric model of an enigmatic wooden tugwreck known locally as the “Mea Tug”.

Discovered by diver and wreck enthusiast Bill Mea, this unidentified steam tug lies in 60 feet of water off the coast of Illinois in Lake Michigan. Originally suspected to be the Luther Loomis, recent underwater archaeological work by the Underwater Archaeological Society of Chicago (UASC) has since ruled out that identity, based on dimensional mismatches and structural differences.

A Tug with Unusual Features

The wreck features an exceptionally rare transversely mounted double-expansion steam engine — a configuration not typically used for direct propulsion. Combined with a plugged propeller shaft hole in the sternpost and a wooden clamp on the flywheel shaft, researchers believe this vessel may have been repurposed for industrial or auxiliary use before being intentionally scuttled.

Thanks to the work of Ken Merryman, who captured 1,468 high-resolution 30MP images, and support from Scott Reimer, Donald Smith, John Bell, and Keith Pearson, this site is now preserved as a photorealistic, interactive 3D model.

We encourage divers, historians, educators, and students to explore the model and share observations — this wreck still holds many secrets. Could you help solve the mystery of its true identity?
