192 - B - Mar del Plata

The 192 - B wreck off Mar del Plata is a fantastic little surprise, especially for divers who enjoy shallow history. We love that it’s right there at just four metres, making it perfect for longer bottom times and even a bit of free diving if that’s your thing. It’s a dangerous wreck, yes, but in a way that creates intrigue, not terror, with its jumbled metal and twisted beams now forming a home for a surprising amount of local fish. You’ll spend your dive poking around the collapsed hull sections, imagining the ship's last moments as you navigate through the structure. Look closely, and you’ll spot crabs scuttling amongst the rust, and schools of silversides often shimmer around the larger fragments. The ambient light at this depth is lovely, painting the wreck in soft blues and greens, and on a calm day, the visibility can be surprisingly good, letting you take in the whole scene. It’s a great pick for newer divers getting comfortable with wreck penetration – or rather, wreck exploration – and a lovely afternoon dive for anyone in the area.

Wreck History - 192 - B

Vessel Type
unknown
Cause
unknown

Resting in the shallows off Mar del Plata, the wreck known only by its designation "192 - B" is a mystery. Its origins, purpose, and the story of its sinking have been lost to time, leaving only a skeletal structure for divers to explore. Lying at a mere 4 meters, this site is exceptionally accessible, making it an ideal spot for novice divers, training dives, or even snorkelers on a calm day.

Despite its easy depth, the wreck is classified as dangerous, likely due to sharp, deteriorating metal plates and potential entanglement hazards. Divers should exercise caution and maintain good buoyancy. For underwater photographers, the shallow depth provides ample ambient light to capture the vibrant marine life that has colonized the structure, turning this anonymous vessel into a beautiful, albeit enigmatic, artificial reef.
