All divers and snorkellers should be aware of high boat traffic around the island. All divers using underwater breathing equipment (SCUBA) must fly or tow the international ‘A’ flag. Visitors in boats should keep at least 50 metres clear of vessels flying this flag, or divers towing the flag. Dive contractors may be working within the moorings areas and dive flag regulations should be observed. For your safety, always log your dives with the metropolitan Sea Rescue groups.
