C-11
Why dive here
With 33+ marine species recorded in the area - including sperm whales - C-11 offers some of Mar del Plata's richest wreck diving. Water ranges 10-21°C, warmest January, February, March.
The C-11 wreck, a former dredger vessel, lies capsized in Mar del Plata’s South Dock at a shallow 11 meters. Sunk in 1975, it’s a pretty somber site, a reminder of the five crew members lost that day. What you get now is a relatively intact hull, flipped over and settled on the seabed. We often find its structure covered in small anemones and sponges, with schools of silversides darting in and out of the openings. It’s a site that really suits newer wreck divers or those looking for a relaxed, shallow dive, especially given the typically calm conditions inside the dock. You can spend a good amount of time just circling the exterior, spotting various crabs tucked into crevices.
