  • Public moorings are located around each of the islands to reduce anchor damage to coral. It is an offence to anchor so as to damage coral ANYWHERE in Cayman waters. These 18 and 30 inch white buoys may be identified by their blue stripe and yellow pick-up line and may be used free of charge. The smaller buoys are designed to hold vessels up to 60 feet long and the larger buoys are for vessels up to 100 feet. Public moorings should not be used when wind speeds reach or exceed 25 knots. Please limit your use of the mooring to 3 hours or less. It is the responsibility of the boat operator to ensure that the mooring is in safe condition – do not leave the boat unattended while on the mooring.
Damaged moorings may be reported to the Department of Environment on 949-8469 or email
