The A.V.H.R. NO.5, just off Mar del Plata, is a solid wreck dive. It’s not the deepest site, sitting at a comfortable 15 meters, making it accessible for newer wreck divers while still offering plenty to poke around. We love how the wreck, a fishing trawler sunk back in the 1950s, has become a home for so much local life. You'll find yourself finning through schools of silversides, darting in and out of the rusted superstructure, and we’ve often spotted conger eels tucked into the darker corners. Entry can be a bit choppy depending on the day, so check the swell before you head out. Once you descend, the visibility usually settles, revealing the full outline of the trawler. Our favourite part is exploring the engine room area, where the light filters in beautifully, illuminating the resident crabs scuttling over the gauges. It’s a proper hands-on wreck, allowing for some nice penetration into the larger sections, though always proceed with caution and good buoyancy. This site is perfect for those who appreciate the history of a wreck as much as the life it now supports.
