Royal Caribbean Cruise Lines is using EcoReefs modules to create a shallow-water snorkeling reef at its Coco Cay shore excursion resort facility. Snorkeling is the resort’s most popular watersports concession, enjoyed by thousands of guests each year. 50 EcoReefs modules were installed in the Coco Cay lagoon area to create a colorful, engaging point-of-interest for snorkelers.  The ecological development of the reef will be measured as part of an ongoing monitoring programme.
