Dive Site: Gregory

About Gregory

The Gregory is a purpose-sunk barge, deployed in 1993, that now rests upside-down off the Dutch side of St. Maarten. Located on the southwest coast, it lies in approximately 16-17 meters (50-55 feet) of water, creating an artificial reef that divers can explore. A natural reef system, rich in corals and sponges, surrounds the wreck, offering a diverse array of marine life. The wreck itself is about 30 meters (100 feet) long and largely intact. An opening on its starboard side provides easy access for experienced divers interested in wreck penetration, while numerous portholes allow those preferring to stay outside to view the interior. The site is a vibrant hub for marine fauna; expect to encounter scorpionfish, angelfish, snappers, parrotfish, grunts, filefish, barracudas, and pufferfish. Eels like morays are common, and southern stingrays may glide by. The wreck walls are home to brave little sergeant majors, diligently guarding their nests, and are also a paradise for blennies. Inside the wreck, nocturnal species such as squirrelfish, glasseye snappers, blackbar soldierfish, and glassy sweepers reside. Various crustaceans, including Caribbean spiny, spotted, and Spanish lobsters, as well as different shrimp and crab species, are also present. Occasionally, a sea turtle or even a dolphin might join the dive party. While largely suitable for various diver levels due to its relatively shallow depth, this offshore site is reached by boat. The mooring line is directly attached to the wreck. The wreck is showing signs of age and crumbling in areas, so penetration should be approached with caution. Sometimes, a drift dive is initiated from the wreck, following the Long Bay Reef. The Gregory is an excellent site for divers to look for abandoned fishing gear, contributing to marine conservation efforts.

Dive profile & how the dive runs

Your dive at Gregory begins with a boat entry, typically mooring directly at the site. The primary route involves an exterior tour around the upside-down barge, exploring its hull, which is covered in vibrant soft corals and barrel sponges. You'll descend to the wreck, which rests on sand at approximately 15-17 meters. The dive progresses by circling the wreck, observing the diverse marine life that shelters within and around its structure. Following the wreck exploration, the dive may extend along the adjacent reef, depending on conditions, allowing for further bottom time. Ascent usually involves a gradual return towards the mooring line, completing a safety stop at 5 meters for 3 minutes before surfacing.

Underwater photography

Gregory offers excellent opportunities for wide-angle photography, capturing the entire upside-down wreck draped in corals, as well as medium-range shots of barracuda, turtles, and eagle rays cruising by. For macro enthusiasts, the wreck's surfaces and nearby reef present abundant smaller subjects like lobsters, moray eels, and diverse reef fish. A wide-angle lens is ideal for showcasing the wreck's scale and the surrounding reef scape, while a macro lens will capture the intricate details of the colorful sponges and corals. Ensure good buoyancy control to avoid disturbing the delicate coral growth and to maintain clear shots. Utilize strobes to bring out the true colors of the marine life and the corals, especially when shooting wide-angle on the wreck.

Getting there & logistics

Access to Gregory is exclusively by boat, typically arranged through local dive operators in St. Maarten, primarily departing from areas like Simpson Bay or Philipsburg. The island is served by Princess Juliana International Airport (SXM), which offers direct flights from various international hubs. Dive trips to Gregory are usually part of a multi-dive package or a single excursion from a dive center, not typically combined into liveaboard itineraries for this specific site. Marine park access requires a dive tag or diving with an authorized dive shop. Fishing and anchoring within 50 meters of moorings are prohibited to protect the delicate marine environment.

Safety & environment

While Gregory is generally a straightforward dive, overhead environments within the wreck require appropriate training, lighting, and caution, making penetration inadvisable for recreational divers without specialized certification. Always dive with a reputable dive operator and ensure your dive guide is aware of your experience level. Nearest recompression chambers are typically located on nearby islands, highlighting the importance of dive insurance, such as that provided by DAN, to cover potential evacuation and medical treatment costs. Always adhere to marine park regulations, including no fishing and respecting mooring rules. Maintain excellent buoyancy to avoid contact with the wreck or reef, protecting both yourself and the delicate ecosystem.
