Dive Site: Kittiwake Reef

About Kittiwake Reef

The USS Kittiwake, a former US Navy submarine rescue vessel, was deliberately sunk in 2011 off Grand Cayman's Seven Mile Beach to create an artificial reef. This 251-foot long and 44-foot wide steel hull is now one of the island's most celebrated dive sites, resting upright on a sandy bottom. The wreck's top is as shallow as 15 feet, with its deepest point reaching approximately 65 feet, making it suitable for divers of varying experience. Its structure has been carefully prepared for exploration, with many interior elements removed to ensure easy and safe penetration through its multiple decks and compartments, including the engine room, galley, and captain's quarters. Over time, the Kittiwake has transformed into a thriving ecosystem, attracting a diverse range of marine life. You'll encounter vibrant corals, sponges, and numerous fish species, making it a fantastic site for both macro and wide-angle photography. The wreck's unique history and accessible layout offer an engaging experience for those interested in historical exploration and underwater photography. Dive operators typically schedule the Kittiwake as the second dive of a two-tank trip due to its shallower depth. This allows for extended bottom time and thorough exploration of its five levels. Its calm, clear waters and structured environment provide an excellent introduction to wreck diving for beginners while still offering plenty to discover for experienced divers.

Conditions & Currents

The waters around the Kittiwake are generally calm, benefiting from Grand Cayman's limited tidal range which results in minimal currents. While mild currents can occur, they are typically manageable, making for a relaxed dive experience suitable for all skill levels. Surface conditions are usually gentle, with minimal swells, aiding easy entry and exit from the boat. Visibility is consistently excellent, often 60-100 feet or more, though it can be temporarily reduced by heavy rainfall or storm activity. There are no significant thermoclines at this depth, ensuring stable water temperatures. Divers should maintain good buoyancy control, especially when exploring the wreck's interior, to avoid stirring up any silt and ensure clear viewing for everyone.

Dive profile & how the dive runs

Dives on the Kittiwake typically begin with a boat descent directly onto the wreck. You will start by exploring the main deck levels, which are approximately 40-50 feet deep. The design of the wreck allows for easy swim-throughs, including the engine room, galley, and crew quarters. Divers often navigate from one end of the ship to the other, observing the marine life that has colonized its structure. As you ascend, you can explore the bridge and upper superstructure, which are in shallower water, around 20 feet. This allows for ample time to photograph the helm station and various features. The final safety stop is conducted above the wreck, often observing the sand bottom for garden eels or occasional stingrays before returning to the boat.

Underwater photography

The Kittiwake is an exceptional site for underwater photography due to its clear water and the wreck's structure. Wide-angle lenses are ideal for capturing the grandeur of the entire vessel and its five decks, as well as the impressive propeller. For interior shots, the open design allows for good natural light penetration, but external strobes or video lights will enhance colors and details within the compartments. Pay attention to subjects like the water cannon, the navigation room, and the mirrors in the bathroom for unique photo opportunities. Macro lenses can be used to capture the smaller marine life and coral growth that now adorn the wreck. Maintain excellent buoyancy to avoid stirring up silt, which can quickly degrade visibility for photos.

Getting there & logistics

Grand Cayman is easily accessible, with direct flights to Owen Roberts International Airport (GCM) in George Town from various international hubs, including Miami. Most dive operations are concentrated along Seven Mile Beach, from where boats depart to the Kittiwake and other sites. Typical dive trips include the Kittiwake as part of a two-tank morning or afternoon excursion. There are no specific additional park fees for diving the Kittiwake itself, beyond the standard dive trip cost. Divers often combine a Kittiwake dive with a shallower reef dive or a visit to Stingray City, making for a varied day of underwater exploration.

Safety & environment

Grand Cayman maintains a high standard for dive safety. The nearest recompression chamber is located in George Town, providing accessible medical support. All divers should ensure they have comprehensive dive insurance that covers emergency medical evacuation and recompression treatment. Site-specific hazards on the Kittiwake are minimal due to its preparation as an artificial reef; all hazardous materials were removed, and openings were enlarged for easy access. Divers should still exercise caution when penetrating the wreck, maintaining good buoyancy control and avoiding contact with the structure. Always dive with a reputable operator and follow your guide's instructions. A dive refresher course is recommended if you haven't dived in over a year, especially for those with fewer than 25 logged dives.
