Dive Experience & Conditions
Descending towards this historical vessel, divers navigate an average depth of 65 meters to reach the main structure. The entire wreck rests on a sandy bottom, an environment that often contributes to good visibility, frequently ranging between 20 and 40 meters (65-130 ft). Currents at this open sea location are noted to be medium, strong, and variable, requiring careful management throughout the dive. Given its offshore position, surface conditions can include noticeable swell and waves, influencing entry and exit procedures. Exploring the sloop's length provides ample opportunity for inspection; its structure, while deep, appears remarkably intact. This is a boat-only dive, suitable exclusively for experienced wreck divers holding technical qualifications.
Dive Difficulty & Safety Guidelines

A crucial requirement for this site is obtaining a special permit from Heritage Malta, as the wreck has been protected since May 1, 2019. Being an offshore site, it's subject to potentially strong and variable currents, along with persistent swell and waves. Thorough dive planning is essential, including detailed gas management and contingency procedures. Maintaining awareness of bottom time and decompression limits is paramount. There are no listed specific marine life hazards, but divers should always maintain respectful distances from the delicate wreck environment and its inhabitants.
