Advanced Rarotonga wreck with broken structure and rich fish life.
Advanced Rarotonga wreck with broken structure and rich fish life.
FV Maritime Reefer is a purpose-sunk fishing-vessel wreck off Rarotonga, created in 1981 and now broken up by storms into a deeper wreck-and-debris site. It is an advanced scuba stop rather than a casual reef swim, with wreck structure and surrounding reef acting as habitat for lionfish, giant morays and occasional pelagic visitors.
