Cozumel’s vibrant underwater world has long been a diver’s paradise, famous for its crystal-clear waters, abundant marine life, and healthy coral ecosystems. But beyond its natural reefs, Cozumel also boasts fascinating artificial reefs that draw divers from all around the world. Here at Sand Dollar Sports, we’re proud to offer unique opportunities to explore these artificial reefs, which play a critical role in coral restoration, marine biodiversity, and sustainable tourism. Among these, our Reef Balls and the C53 Ship are two exciting highlights that provide a spectacular diving experience and help protect Cozumel’s delicate marine ecosystem.
The Purpose of Artificial Reefs
Artificial reefs are human-made structures designed to promote marine life by offering safe habitats and encouraging coral growth. These structures become valuable spaces for fish, coral, and other marine life, especially as they mimic the qualities of natural reefs. Over time, fish, crustaceans, mollusks, and even coral colonies settle in, transforming once-empty spaces into vibrant ecosystems. By increasing biodiversity, artificial reefs play a crucial role in supporting healthier oceans, offering shelter and food sources for marine species while helping to restore balance to the reef.
They also relieve some of the pressure on Cozumel’s natural reef systems by offering divers new sites to explore, further supporting sustainable tourism efforts.

The C53 Shipwreck: Cozumel’s Historic Wreck Dive
One of the most captivating artificial reefs in Cozumel is the C53 Shipwreck, a former Mexican Navy minesweeper. Purposefully sunk in 2000, the C53 now rests at a depth of approximately 80 feet and has been transformed into a thriving underwater ecosystem. This 184-foot-long ship has become a haven for marine life, including moray eels, groupers, and queen angelfish, glassfish, barracudas, and colorful parrotfish.
Diving through the C53, divers can explore its open cabins and corridors, which are home to countless marine species. The inner recesses are filled with glasfish and groupers chasing after them. There are also a myriad of sponges on the ship and within its recesses. Divers especially love the anchor and rudder that are now covered with colorful sponges and corals. Many fish make their haven under the bow. It’s a unique experience that combines history and nature, giving divers a glimpse into both the past and the dynamic life now flourishing around the wreck.
Sand Dollar Sports Reef Balls: Guardians of Coral Growth
Another vital component of our artificial reef program is our Reef Balls. Designed to mimic natural reef formations, these carefully crafted structures promote coral attachment and growth while providing shelter for small fish and other marine organisms. The Reef Balls are constructed from environmentally safe materials that encourage coral larvae to settle and grow, creating new habitats that sustain marine life.
With our commitment to reef restoration, Sand Dollar Sports has installed numerous Reef Balls at strategic locations, aiming to restore damaged reef areas and offer alternative dive sites. These installations are part of our broader effort to educate, protect, and sustain Cozumel’s underwater wonders for future generations. Sand Dollar is working to be one of the most sustainable scuba diving centers in Cozumel.
Discover Other Artificial Reefs in Cozumel
In addition to the C53 Ship and Reef Balls, Cozumel is also home to the Zoe Living Sea Sculpture, an inspiring artificial reef designed to encourage coral growth and biodiversity. Zoe Living Sea Sculpture was started in memory of a young woman, Zoe, who tragically lost her life to carbon monoxide poisoning from a faulty heater. The site where Zoe Living Sea Sculpture is located has suffered significant damage due to unsustainable development and hurricanes. Local divers and conservationists are actively working to restore the reef, and the Zoe Project plays a key role in this important mission. This unique structure serves as a habitat for diverse marine species, offering divers an eco-friendly, interesting site to explore.
Our house reef is also filled with coral reef platforms that are home to coral fragments that we are growing into healthy corals to be replanted on the reef. In partnership with the Cozumel Coral Reef Restoration Program, we cultivate and rehabilitate damaged corals in our aquarium and coral nursery before transplanting them onto the Villablanca Reef. Through this collaboration, we have established 29 coral restoration structures and replanted more than 10,000 coral fragments, helping to restore and protect Cozumel’s marine ecosystem!
Our newest project involves growing elkhorn and staghorn coral fragments, which are critically endangered. Researchers estimate that between 1980 and 2006, when it was added to the Endangered Species Act (ESA), the Elkhorn coral population declined by approximately 97%. This drastic decline resulted from multiple factors, including disease, excessive algae growth, climate change, ocean acidification, and human impact. In May 2006, Elkhorn coral, along with staghorn coral—another member of the Acropora genus—was officially classified as threatened under the ESA. Conservation efforts are critical for these corals.
