Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
A substantial freighter built in 1920, the Saint Prosper rests on a bottom of sand and rocks off the Spanish coast. Sunk on March 8, 1939, after striking a floating mine, the vessel forms a poignant historical site and complex underwater structure.
Measuring 106 meters in length (approximately 348 feet) and displacing 4330 tons, the wreck provides ample exploration area for qualified divers. Access is exclusively by boat, requiring precise surface navigation to the site; divers must be prepared for potentially choppy surface conditions depending on the weather. Surrounding topography includes sand and rock features, but the imposing wreck dominates the underwater landscape, offering numerous external exploration possibilities.
Divers can navigate the deck structures, observe the hull integrity, and explore the vast exterior for signs of marine life. Descending to deep ranges, a dive here necessitates appropriate training and gas management protocols.
Visibility typically ranges from 5 to 10 meters, averaging 7 meters, influencing underwater navigation. Medium currents can also be present, requiring divers to manage their positioning actively throughout the dive.
Considered an extremely technical dive, it's reserved for expert divers who possess the necessary experience and equipment.

Best Time to Dive
Optimal diving conditions for Saint Prosper typically emerge during the warmer, drier months, presenting a stark contrast to the cooler, sometimes choppier winter period. From April through October, dive scores consistently rank as "Good," indicating more favorable surface conditions. Air temperatures during these months range from 15.5 to 26°C (60 to 79°F), making surface intervals more comfortable. Wave heights also tend to be lower, averaging between 0.63 and 1.0 meters (2.1 to 3.2 ft) during this peak season. Rainfall remains minimal, often below 1.5 millimeters, equating to about 0.06 inches per month, which generally correlates with better visibility days. Conversely, the winter months, particularly January, February, and March, see "Moderate" dive scores due to cooler air temperatures, higher wave heights around 1.2 meters, close to 4 feet, and increased wind speeds. While diving is possible year-round for experienced cold-water divers, the period from late spring to early autumn offers the most consistent and pleasant conditions for accessing this deep wreck. Water temperature data is not consistently reported for this location, so divers should be prepared for varying thermal conditions based on the season.

Dive Experience & Conditions
For experienced wreck divers, descending to Saint Prosper presents a challenging yet rewarding experience, reaching its maximum depth. Requiring advanced certifications and precise buoyancy control, a dive here often encounters medium currents. Good finning techniques and situational awareness are essential to maintain position around the substantial structure. Visibility averages around 7 meters, varying between 5 and 10 meters, so divers must be comfortable with less than clear conditions and rely on navigation skills. Water temperatures are not consistently reported; therefore, selecting appropriate thermal protection based on season and personal comfort is important. Given its classification as an "extremely technical" and "expert" dive, paramount skills include deep diving, wreck penetration (if applicable), and emergency procedures. Commencing from a boat, dives here require preparation for potential surface chop during entry and exit, particularly if moderate wave heights are present.
Dive Difficulty & Safety Guidelines
Navigating the Saint Prosper wreck demands careful attention to specific hazards inherent to deep wreck diving. The primary concern is the presence of fishing nets entangled on the wreck, posing a significant entanglement risk. Divers must carry appropriate cutting tools and be proficient in their use. Given the maximum depth of 40 meters, approximately 130 feet, decompression procedures and gas management are critical; this is not a recreational profile. Medium currents can also affect buoyancy and propulsion, requiring divers to plan their route and entry/exit points strategically. This site is specifically designated for "experienced wreck divers only" and is considered "extremely technical," underscoring the need for advanced training beyond basic certifications. Adequate training in deep diving, wreck diving, and potentially technical diving, along with robust equipment, is essential. Always dive with a reliable buddy and ensure emergency protocols are well-rehearsed, particularly concerning deep-water rescues or lost diver procedures on a complex structure.
