C-53 Shipwreck Dive Site
Overview
The C-53 Shipwreck is one of the most well-known wreck dives in Cozumel scuba diving, resting upright in moderate depth within the Cozumel Marine Park. This former Mexican Navy minesweeper was intentionally sunk in June 2000 and has since developed into an established artificial reef.
While compact enough to be explored in a single dive, the wreck’s structure and optional interior routes make it best suited for experienced divers seeking controlled wreck exploration rather than casual reef diving.
Site Overview & Conditions
Depth Range: Approximately 50–70 feet (15–21 meters)
Currents: Variable; often mild but can change depending on daily conditions
Visibility: Typically good, allowing the entire wreck to be seen in clear water
Entry Style: Boat dive with direct descent onto the wreck
The wreck sits on a sandy bottom with minimal surrounding reef, keeping diver focus centered on the structure itself.
Key Features
Wreck Type: 184-foot (56 m) Mexican Navy minesweeper
Orientation: Upright and intact
Structural Features: Decks, passageways, hatches, and multiple exit openings
Reef Development: Increasing sponge and coral growth on steel surfaces
A fixed guideline runs much of the length of the wreck, assisting with navigation for exterior and interior tours.
Dive Experience & Safety Considerations
Difficulty Level: Intermediate to advanced
Who Should Dive This Site: Certified wreck divers, experienced recreational divers with solid buoyancy control, and divers accompanied by a qualified local guide
Who Should NOT Dive This Site: Newly certified divers without wreck experience or divers uncomfortable with overhead environments
Group Diving Expectations: Divers remain close to the wreck; penetration dives are conducted in small, closely supervised groups
Wreck penetration should only be attempted with appropriate training, equipment, and supervision. A primary dive light is strongly recommended, even during daylight dives, due to dark interior passages.
Marine Life Highlights
Common: Glassy sweepers, blennies, cleaner shrimp, starfish
Occasional: Green moray eels, spiny lobster, peacock flounder, mantis shrimp
Rare: Nurse sharks, turtles, seahorses, scorpionfish
Marine life is most concentrated inside shaded compartments and along the wreck’s metal surfaces rather than in the surrounding sand.
