The Ultimate Guide to Phuket’s Historic Deep Wreck Dive Site: The King Cruiser Wreck
The Dramatic Sinking of the King Cruiser
The King Cruiser was a Japanese-built twin‑hulled ferry carrying passengers between Phuket and the Phi Phi Islands.
On May 4, 1997, during a routine crossing, it struck a submerged pinnacle at Anemone Reef and suffered a large hull breach. Despite the sudden danger, the ferry sank slowly – taking about 2½ hours to go under – allowing for the safe evacuation of all 561 passengers by nearby patrol boats and fishing vessels. One elderly passenger sustained a spinal injury, and several others suffered minor trauma.
Speculation quickly swirled about the cause. Although navigational errors were obvious, there were many rumours. Yet, official investigations concluded that the captain was negligent, and no credible evidence of foul play surfaced. The speculations in aftermath to the accident only added to the wreck’s allure as a dive site.
Where the King Cruiser Wreck Lies Today
Now resting on the sandy seabed about 30-33 m deep, the King Cruiser sits upright. The highest part of the structure reaches around 18-22 m owing to partial collapse above. The wreck has impressive dimensions of 85 m long and 25 m wide. It spans four decks, including what were once engine rooms, vehicle decks, passenger lounges, and the wheelhouse.
During its sinking, the upper deck collapsed. Divers descend using mooring lines dropped at the bow or stern. Due to its deteriorating state, penetration is prohibited, although there are still many interesting aspects to experience.

Divers should descend with care, using the lines and following dive-guide instructions. Moreover, with penetration prohibited, the outer structures still pose entanglement and injury hazards. Divers should stick to exterior exploration, from above and to the sides. The car deck and lower passenger areas make for great viewing of what once was.
Artificial Reef & Marine Life Explosion
Coral & Invertebrates
Delicate soft corals, vibrant sponges, and plate coral now encrust the wreck’s surfaces. Sea fans hang from beams, and nudibranchs, anemones, and crabs flourish in protected crevices.
Schools of Fish
Divers are greeted by sweeping clouds of yellow snapper, fusiliers, rabbitfish, and bigeye trevally. During the ascent, barracuda and rainbow runners often circle above the wreck in search of food – making for dramatic underwater scenes.
Predators & Sharks
At the sandy bottom, gray bamboo sharks, and leopard sharks occasionally appear. More rarely, divers report sightings of whale sharks in nearby waters.
Macro Life & Critters
Closer inspection reveals lionfish, scorpionfish, moray eels, and shy rarities like pipefish or juvenile hawksbill turtles. These hidden treasures reward careful eyes and patient divers.
Together, this biodiversity creates an immersive experience where structure and nature combine beautifully. The wreck’s shady corridors and rusted framework welcome diverse life – ensuring every dive reveals new surprises.
