MV Captain Keith Tibbetts

MV Captain Keith Tibbetts — Cayman Brac, Cayman Islands

The MV Captain Keith Tibbetts is a former Soviet Frigate (Project 159A, NATO code Petya II class) — a 330-foot anti-submarine warfare vessel that served in the Cuban Revolutionary Navy under the name Cañonazo before being acquired by the Cayman Islands government and sunk as an artificial reef on 17 September 1996 off the north coast of Cayman Brac.

The deliberate sinking was timed to coincide with the island's Dive Brac week, and in the nearly three decades since, the wreck has become one of the Caribbean's most celebrated dive sites — not only for its history but for the quality of marine growth that 30 years of tropical reef colonisation has produced.

The Wreck

The Tibbetts lies on her starboard side at 15–30 meters, with the port side gunwales accessible at 15 meters and the keel and deepest deck sections at 30 meters. The military architecture — gun mounts, torpedo tube housings, sonar domes, bridge structure, propeller shafts — is still recognisable despite the encrustation.

Coral growth covers every horizontal surface: brain corals, star corals, encrusting gorgonians. Sea fans the size of dinner tables grow from the gun housings. Barrel sponges colonise the torpedo tube platforms. Schools of silversides and glassfish pour through the superstructure openings, drawing tarpon that cruise the hull in pairs.

The interior is penetrable in the largest compartments — the engine room is accessible — but many sections have corroded or collapsed and require technical dive configuration. The external circuit, available to any Advanced Open Water diver, is substantial on its own: two dives to cover the length of the vessel adequately.

Cayman Brac Context

Cayman Brac is the least visited of the three Cayman Islands. Direct flights from Grand Cayman (15 min) or Miami (3 hrs) land at Gerrard-Smith Airport. The island has two main dive operators, a small resort community, and almost no dive crowds. Conditions on the Tibbetts are consistently calm and the water temperature stays 27–29°C year-round.

Practical Info

• Depth: 15–30m | Difficulty: Intermediate — stable wreck, manageable current, good visibility (20–30m typical)
• Access: Day trips from Cayman Brac resorts; flights from Grand Cayman
• Best season: Year-round; December–April for flattest seas
• Marine life: Tarpon, queen angelfish, silversides, moray eels, groupers, sea fans, barrel sponges
