Dive Experience & Conditions
Beginning your descent to the Capt. Shirley Brown Memorial Reef typically places you on a mid-depth artificial structure, making it best suited for intermediate divers. Descending, the top deck of the wreck reaches around 22 m (75 ft) below the surface, providing an initial point of exploration. Continuing deeper, the wreck ultimately rests at a maximum depth of 25 m (85 ft). Visibility here can vary depending on local weather and sea states, as detailed site-specific reports are limited. Without consistent community logs, divers should anticipate a range of underwater clarity and be prepared for potential currents that are typical in open Gulf waters. The site's exposure profile suggests varied conditions influenced by incoming swell, requiring attentive pre-dive planning.
Dive Difficulty & Safety Guidelines
Approaching Shirley Reef responsibly means recognizing its profile as an intermediate wreck dive, necessitating an advanced diver certification. Its depth range, reaching 25 m (85 ft), requires careful adherence to no-decompression limits and diligent gas management practices. As an artificial reef wreck, potential hazards include entanglement points from structural integrity or marine growth, which demand proficient buoyancy control and situational awareness. Divers should always plan their boat entry and exit meticulously, given the offshore location south of Perdido Pass. Without specific reported hazards, general wreck diving best practices are paramount. This includes carrying appropriate signaling devices and ensuring all equipment is well-maintained for an offshore environment.
