The Anna Blanca isn't about deep dives or big pelagics. It’s about history, atmosphere, and the sheer joy of a shallow wreck. This pilot boat sits upright in just seven metres of water, perfectly preserved by Mar del Plata's cool, calm currents. We love gliding over her deck, imagining the last moments before she found her final resting place. The wheelhouse is still largely intact, and it’s a real thrill to peer inside, the faint light filtering through the portholes. Over the years, the wreck has become a home. We’ve spotted conger eels peeking from beneath plates of rusted metal, their eyes following us with an almost curious gaze. Patagonian blennies dart in and out of every crevice, while small schools of silversides shimmer around the mast. The shallow depth means fantastic bottom times, so you can really take your time exploring every nook and cranny. Our favourite part is lingering on the bow, watching the light play across the encrusting sponges and anemones. It’s a gentle dive, best suited for those who appreciate the quiet beauty of an artificial reef and a tangible connection to the past.

ANNA BLANCA Wreck History

Vessel Type

pilot boat

Cause

unknown

Resting in the shallows off the bustling port of Mar del Plata, the Anna Blanca is an accessible but mysterious wreck. Little is known about the history of this former pilot boat or the circumstances of its sinking. Lying at a maximum depth of just 7 meters, its remains are scattered across the seabed. Its designation as a 'dangerous wreck' means divers should exercise caution, as the broken structure presents potential hazards like sharp metal edges and entanglement risks. Despite this, the shallow depth makes it an interesting site for novice wreck divers or as a second dive of the day, offering a glimpse into the past and a habitat for the local marine life accustomed to coastal waters.
