Site Overview

The Phu Quoc Wrecks consist of several small sunken fishing boats that have been transformed into productive artificial reefs by years of marine colonisation in the Gulf of Thailand. While not large purpose-sunk wrecks comparable to dedicated wreck diving destinations, these small vessels support impressive fish biomass and biodiversity that significantly exceeds the surrounding sandy bottom habitat. Large groupers have claimed the vessel interiors and larger openings as their territory, with several impressive specimens regularly observed sheltering in the darker recesses. Moray eels occupy every suitable crevice in the deteriorating hull structures, while lionfish have colonised the exterior surfaces in remarkable numbers, creating dense predator populations around each wreck. Batfish patrol the upper structures and surrounding waters in their distinctive formation flying. The wrecks rest at depths of 12 to 20 metres on sandy bottoms, making them accessible for Advanced certified divers without specialised wreck training. The relatively small size and open design of the fishing vessels allows light penetration and easy external navigation. The wrecks demonstrate how even small artificial structures can support significant marine biodiversity, providing an interesting ecological perspective alongside the diving experience. They are typically combined with reef diving sites in full-day trips from Phu Quoc.

Dive Briefing

"Descend to the wreck structure at approximately 12 to 15 metres and orient to the vessel's outline resting on the sandy bottom. Circle the exterior examining the marine colonisation that has transformed the fishing boat into a living reef. Large groupers shelter in the larger openings and interior spaces, visible from the exterior without requiring penetration. Moray eels occupy the numerous crevices created by the deteriorating hull, while lionfish hover near every overhang and surface. Batfish patrol the water column above the wreck, and snapper aggregate around the structure attracted by prey concentration. Examine the sandy perimeter for stingrays and garden eels influenced by the artificial reef productivity. The wreck surfaces are heavily encrusted with sponges, oysters, and soft corals creating colourful photographic compositions. Ascend gradually along the wreck superstructure for a safety stop, deploying your DSMB before the final ascent. Multiple wreck sites in the area may be visited during a single diving day."
