Dive Site: USS Kittiwake

About USS Kittiwake

The USS Kittiwake is a renowned wreck dive located just off Seven Mile Beach in Grand Cayman, attracting divers of all experience levels. This 76-meter (251-foot) former U.S. Navy submarine rescue vessel, originally launched in 1945 and decommissioned in 1994, was intentionally sunk in 2011 to create an artificial reef. Its upright position on a sandy bottom, with depths ranging from 11 to 20 meters, ensures excellent natural light penetration and easy access for exploration. Before its sinking, the Kittiwake underwent extensive preparation, including the removal of hazardous materials and the creation of wide swim-through passages. This meticulous planning ensures a safe and engaging wreck experience, allowing divers to explore five decks, including the pilot house, engine room, decompression chamber, and mess hall, all with clear exit awareness. The wreck's structure provides ample opportunities for both exterior viewing and interior penetration, catering to diverse diving preferences. Since its new role as an artificial reef, the Kittiwake has become a vibrant marine habitat. Encrusting corals, sponges, and sea fans are steadily colonizing the hull and deck. The wreck teems with schools of fish, barracuda, various species of eels, and occasional sightings of turtles and rays. This dynamic environment makes it a compelling subject for underwater photography and marine life observation. Conditions at the Kittiwake are consistently favorable, with year-round water temperatures between 25–29°C and excellent visibility often exceeding 25 meters. Typically, currents are mild to moderate, allowing for relaxed exploration. Its proximity to shore and preparation for diving make it a cornerstone of Grand Cayman's dive offerings, suitable for newly certified divers to advanced wreck enthusiasts.

Conditions & Currents

Currents at the USS Kittiwake are typically mild to moderate, making it suitable for divers of various experience levels. However, conditions can vary, and it's essential to check with local dive operators for the day's specific current forecast, particularly as the wreck occasionally shifts orientation during severe storms. Entry and exit are usually straightforward boat dives, often aided by permanent moorings, which are standard practice in Cayman Marine Parks where anchoring is banned. Visibility is consistently excellent, often exceeding 25 meters, thanks to the remote location and marine protection efforts, although very occasionally tide changes or heavy rainfall might slightly reduce it. There are no notable thermoclines within the wreck's depth range, ensuring consistent water temperatures.

Dive profile & how the dive runs

Diving the USS Kittiwake typically begins with a boat entry directly over the wreck. As you descend, the wreck's superstructure becomes visible almost immediately due to the clear visibility. The dive often starts at the top of the wheelhouse, around 11 meters, allowing for a gradual exploration downwards. Divers can follow pre-cut pathways through the five decks, navigating through the pilot house, engine room, and mess hall. Natural light floods these internal spaces, minimizing any feeling of claustrophobia. A common route involves exploring the upper decks and accessible interior compartments before moving towards the lower sections and the impressive propellers at the stern, which lie around 20 meters. The wreck is large enough for multiple exploration circuits, and your guide will typically lead you along a route that maximizes observation of marine life and structural features. Safety stops are usually conducted on the top sections of the wreck or in the surrounding shallow sandy areas, often extending bottom time with Nitrox to fully appreciate the site.

Underwater photography

The USS Kittiwake offers outstanding opportunities for underwater photography, appealing to both wide-angle and macro enthusiasts. For wide-angle shots, a fisheye lens or wide-angle rectilinear lens is ideal to capture the grandeur of the entire 76-meter wreck, its various levels, and the open swim-throughs, especially when sunlight streams through the interior. External strobes are highly recommended to bring out the vibrant colors of developing corals, sponges, and schooling fish against the blue water. When exploring the interior, a video light or focus light is invaluable for illuminating darker areas and enhancing focus. For macro photography, look for smaller inhabitants like moray eels, lobsters, and nudibranchs that have colonized the wreck. Maintaining excellent buoyancy control is crucial, especially within the wreck, to avoid stirring up silt and to protect the delicate marine growth. Always practice a non-touch approach to preserve the wreck's integrity and its inhabitants.

Getting there & logistics

Grand Cayman is served by Owen Roberts International Airport (GCM), with numerous direct flights from North America and the UK. Divers typically stay in resorts or condos along Seven Mile Beach, which is conveniently close to the Kittiwake. Dive operators on Grand Cayman offer daily two-tank dive trips, often combining the Kittiwake with another West Wall site or a nearby reef. Most dive centers provide complimentary pickup services along Seven Mile Beach. Trip lengths vary, but a 5–7 day stay allows for comprehensive exploration of Grand Cayman's dive sites. Marine park fees are usually included in dive trip costs. The Kittiwake can also be combined with shore diving opportunities like the Sunset House Mermaid for a diverse itinerary.

Safety & environment

Diving the USS Kittiwake is generally considered safe due to its shallow depth, excellent visibility, and the extensive preparation undertaken before sinking to remove hazards and create clear passages. However, standard wreck diving protocols should always be followed, including maintaining good buoyancy, using a dive light for interior exploration, and avoiding contact with the wreck or marine life. Always dive with a certified guide who is familiar with the wreck's layout, especially if attempting penetration. The nearest recompression chamber is located on Grand Cayman, typically at the Health City Cayman Islands hospital. Divers should always have comprehensive dive insurance that covers emergency medical treatment and evacuation. Given the wreck's location offshore, boat access ensures rapid response in case of an emergency, though evacuation to the chamber can take time.
