Yong Hua Shipwreck

Koh Lipe · Satun · Thailand

The Yong Hua Shipwreck lies south of Koh Lipe in Thailand's Tarutao National Marine Park, a Chinese cargo vessel resting upright on a sandy bottom at 28 metres as though it simply settled there by choice. The wreck has become the Andaman Sea's most rewarding accessible wreck dive, its hull and superstructure transformed by years of marine colonisation into a living reef that attracts both resident and visiting marine life in remarkable density. The vessel measures approximately 40 metres from bow to stern and sits on a flat sandy seabed that provides excellent contrast for photography. Approaching from the mooring line, the wreck materialises gradually from the blue at around 20 metres visibility, its outline softened by the dense growth of soft corals, sponges, and hydroids that cover every horizontal and vertical surface. The hull has become a substrate garden where purple and orange soft corals compete for space, their polyps extending in the mild current to create a living fur coat over steel. The first feature that commands attention is the barracuda school. Hundreds of yellowtail barracuda have adopted the wreck as their permanent residence, forming a spiralling column above the superstructure that rises toward the surface. The school compresses and expands in response to diver approach, creating constantly shifting silver formations against the blue background. Batfish hover in the shelter of the bridge structure in groups of 10 to 20, their disc-shaped bodies tilting to observe divers with apparent curiosity. Penetration of the Yong Hua is straightforward for experienced divers. The main cargo hold is accessible through wide deck openings, its interior colonised by lionfish that hang inverted from the ceiling, their venomous spines fanned in elaborate displays. Groupers of substantial size have claimed territories within the hold, their bodies too large to have entered through any opening, suggesting years of uninterrupted residency as they grew within the wreck's confines. The engine room, darker and tighter, rewards careful exploration with macro subjects including nudibranchs, decorator crabs, and resident moray eels coiled in the machinery spaces. The exterior of the hull supports a different community. Scorpionfish rest on horizontal surfaces, virtually invisible against the growth. Cuttlefish hover alongside the hull, their chromatophores rippling in displays of colour that range from deep brown to iridescent green. Schools of glassfish fill every sheltered space, their transparent bodies creating shimmering clouds that part and reform around exploring divers. The sandy seabed around the wreck is worth attention. Blue-spotted stingrays rest on the sand in the wreck's shadow, and the occasional guitar shark has been spotted lying partially buried beyond the stern. The contrast between the living complexity of the wreck and the clean sand surrounding it makes the Yong Hua feel like an oasis, a concentrated island of life in an otherwise featureless landscape. Diving the Yong Hua requires reasonable depth management as bottom time at 28 metres is limited, but the wreck's compact size means a thorough exploration is possible within a standard air dive. The mild currents and consistently good visibility of the Koh Lipe area make this an exceptionally reliable dive, and the wreck's upright posture means orientation is intuitive from the moment of arrival.
