Cozumel Wreck Diving: C-53 Felipe Xicoténcatl Guide

Cozumel wreck diving, in the way most visitors mean it, is one ship: the C-53 Felipe Xicoténcatl. The island is a drift-reef destination first. Palancar, Colombia, and Santa Rosa are the dives people fly for. The wreck is the special trip — a 56-metre minesweeper sitting upright on sand near Chankanaab, close enough to town that it fits a two-tank morning.

She began life as USS Scuffle (AM-298), an Admirable-class minesweeper built in Tampa in 1943–44. She earned a Presidential Unit Citation and five battle stars in the Pacific, then went to Mexico in 1962. After decades as a navy patrol boat she was stripped, towed, and scuttled as an artificial reef on 6 June 2000. Hurricane Wilma shoved her about 30 metres north in 2005. She stayed upright.

This guide covers the story, the 12–25 metre profile, who can dive her, Cozumel current, and why “open hatches” still are not a free pass. For wreck diving as a skill, start with the wreck diving hub.

The Story of the Wreck

USS Scuffle was a working minesweeper, not a liner. Admirable-class ships were the US Navy’s small, hard-used Pacific workhorses: wooden-adjacent steel, guns, sweep gear, and a job that involved finding things designed to sink other ships. After the war she sat in reserve, then transferred to the Mexican Navy in October 1962 as ARM DM-05. In 1994 she was renamed ARM General Felipe Xicoténcatl (C-53) for a Mexican military hero, and spent years on Gulf and Caribbean patrols.

When she was retired in 1999, Cozumel’s watersports association, local shops, and the marine park asked to sink her as a reef. The site was a sand bank near Chankanaab, chosen so the hull would not crush living reef. Hazardous fluids and loose gear were removed. Holes were cut so water and fish could move through the hull — and so later divers would have obvious, relatively wide openings rather than a sealed steel box.

That last point is easy to misread. Cut-outs make the wreck more visitable. They do not make every companionway a recreational swim-through. Overhead is still overhead. Silt still exists. The park still expects you to leave sponges on the steel.

Wilma in October 2005 moved the ship. Operators still dive her as an upright wreck on sand. She is not a war grave. She is a scuttled navy ship in a protected park. Photograph, hover, leave.

Depth and Dive Profile

Image by Martin Str

Typical numbers:

• Sand / keel: about 24–25 metres (80 feet)
• Main deck and superstructure: often 12–15 metres, depending which part you are on
• Length: about 56 metres (184 feet)

Open Water’s limit is 18 metres. The top of the C-53 can sit inside that. The interesting hull and the sand do not. A “full wreck dive” here is an Advanced profile even if you never go inside.

Visibility on Cozumel’s west side is often excellent — 20–30 metres is not unusual — so the ship can appear as a complete silhouette on the descent. Water is typically 26–28°C. A 3 mm suit is enough for many visitors; bring a hood if you run cold on a 25-metre second dive.

No-stop time at 24 metres on air is shorter than it feels when you are circling a 56-metre hull. Nitrox is useful if you are certified. It does not raise your maximum depth. Plan the wreck as one thorough exterior, not as “we will do the engine room if we have gas left.”

Depth limits by card are in how deep you can scuba dive. The C-53 sits right on the Open Water / Advanced line. Do not bargain the extra six metres because the vis is pretty.

Accessibility: Boat, Park, and Season

This is a boat dive from Cozumel’s west-coast shops, usually paired with a reef as the second tank. It is not a shore entry you walk to from a hotel beach. Chankanaab is close; the ride is short compared with a northern Red Sea wreck day.

The wreck sits in Parque Nacional Arrecifes de Cozumel. You dive with a licensed operator, pay the park fee, and follow no-touch rules that are stricter than many Caribbean islands. Gloves may be restricted. That is the park, not the shop being difficult.

Cozumel is diveable year-round. Summer is warmer and can bring more visitors. Northers in winter can chop the surface and change the day’s sites. The C-53 was sited partly for shelter, but “sheltered relative to Colombia Wall” is not the same as “no current.” Build a spare day if the wreck is the reason you came.

There is no special wreck permit beyond diving with a park-authorized boat. Ask the shop before you book whether they take Open Water divers on the C-53 that week, and whether interiors are off the plan without wreck training.

Skills and License Required

PADI Open Water (18 m): Possible for a conservative exterior of the superstructure if the operator agrees, the current is mild, and you stay off the sand. Many shops prefer Advanced. A Discover Scuba dive will not reach the hull; DSD limits sit around 12 metres.

PADI Advanced Open Water (30 m): The card that matches a proper C-53 dive. 25 metres plus current is a normal Advanced problem, not an expert one — if your buoyancy is already decent. If it is not, do a reef dive first. Read the Advanced Open Water guide if you still need the course.

Deep specialty: Not required. 25 metres is inside Advanced.

Wreck specialty: Required before you treat the cut-outs as a route through the ship. Lights are mandatory in any interior, specialty or not. A wreck diving certification is the right add-on if this is the dive you came to Cozumel to repeat.

Cozumel current is the other skill. Drift reefs teach you to fly. A wreck teaches you to stop, hover, and not crash into steel when the water still wants to move you. If your only dives have been Palancar, brief the wreck as a different sport.

What You Will See

From the line you get an upright navy ship on white sand: bow, superstructure, stern, the sense of a complete vessel rather than a debris field. In good vis the whole 56 metres can sit in one wide-angle frame.

Growth is Caribbean: sponges, coral, and the usual Cozumel fish. Glassy sweepers pack darker openings. Barracuda sometimes hang off the upper works. Morays and grouper use the hull as a house. Photographers come for silhouette and for the contrast of steel against sand, not for wartime trucks in a hold.

Inside — if you are trained and the shop is running a penetration — you get companionways, the idea of an engine space, and silt if anyone frogs incorrectly. It is a minesweeper, not the Thistlegorm. Do not expect cargo dioramas. Expect structure, light shafts from the cut-outs, and a reason to have a backup torch.

If you want a wreck with cargo still in situ, that is the SS Thistlegorm, not Cozumel. If you want a shallow warship without Caribbean current, Malta’s HMS Maori is the other comparison.

How to Dive It

Descend on the mooring. Do not free-drop in current and hope you hit 56 metres of steel. At the wreck, agree bow or stern as the first waypoint. A ship this size in current is easy to split a pair on.

Stay outside unless you have wreck training and a planned interior. Cut-outs look inviting. They are still overhead. If vis inside drops, you are in a silt-out on a holiday dive. That is a bad story.

Watch your computer at 24 metres. The wreck is interesting enough to overstay. Turn on gas, not on “one more look at the stern.” Send an SMB if that is how the boat runs pickups — Cozumel boats are used to drifting divers, but a wreck dive may end back on a line. Listen to this briefing, not yesterday’s reef briefing.

No taking. No sitting on the rail. Park rules plus basic wreck manners. For general wreck hazards — entanglement, sharp metal, silt — see scuba diving safety.

Practical Logistics

Stay in San Miguel or along the west coast where the boats leave. The C-53 is a half-day add-on, not a liveaboard destination. Two-tank trips often pair the wreck with a nearby reef so nitrogen and the day’s weather both work.

Bring a torch even for an exterior; the hull throws shade. Bring a computer. Nitrox if you have it. A pointer or a well-stowed gauge so you are not dangling into sponges.

Ask the shop three questions: Open Water allowed or not; interiors or exterior-only; how they handle current on the descent. Skip slogans about “the only wreck in Cozumel.” There is one famous hull. The skill is matching it to your card.

Cozumel wreck diving sits on the same “best in the world” conversation as Florida’s Spiegel Grove: warm water, purpose-sunk or park-managed steel, easy flights from North America. It is not Truk and it is not Coron. It is a very good single-ship dive on an island that is otherwise about walls.

Final Thoughts

The Cozumel wreck dive is the C-53 Felipe Xicoténcatl: USS Scuffle, Mexican navy, scuttled 2000, upright on sand at about 24–25 metres, superstructure shallower, boat from town, marine park rules. Open Water can see the top on a kind day. Advanced Open Water is the card for a proper tour. Wreck training is the card for the inside.

Treat the current as part of the site. Leave the steel alone. Then go back to Palancar knowing you actually dived a ship, not only a wall.
