The King Cruiser Wreck, Phuket, Thailand

The King Cruiser Wreck is one of the most famous scuba diving sites in Phuket and remains one of Thailand’s best-known wreck dives. Located southeast of Phuket near Shark Point and Anemone Reef, the wreck attracts experienced divers looking for a deeper and more challenging dive experience.

Over the years, the wreck has transformed from a sunken passenger ferry into an artificial reef covered in marine life. However, time, currents, storms, and corrosion have significantly changed the structure of the wreck itself, turning it into a far more advanced dive site than it once was.

In this blog, we explore the history of the King Cruiser Wreck, the story behind its sinking, the marine life now found there, and why this site is now recommended only for confident and experienced divers.

The History of the King Cruiser Wreck

The story of the King Cruiser Wreck began on May 4, 1997.

At the time of the accident, the vessel carried approximately 561 passengers, including both Thai locals and tourists, while operating its regular ferry route between Phuket and the Phi Phi Islands.

Originally built in Japan in 1968 under the name MS Rhein, the vessel operated as a passenger and vehicle ferry. The ship measured approximately 85 metres in length and could carry around 800 passengers and several vehicles.

While travelling between Phuket and Phi Phi, the King Cruiser struck the submerged Anemone Reef pinnacle, one of Phuket’s most famous dive sites.

The collision caused major structural damage to the hull and the vessel eventually sank within a few hours.

Fortunately, all passengers were safely evacuated and no lives were lost. Local fishing boats and nearby vessels assisted with the evacuation before the ship disappeared beneath the surface.

What began as a maritime accident would eventually become one of Phuket’s most famous artificial reefs and scuba diving attractions.

Rumours Surrounding the Sinking

Over the years, various rumours have circulated regarding the sinking of the King Cruiser.

Some stories suggested the captain may have been intoxicated, while others speculated about possible insurance-related motives surrounding the accident.

However, there has never been any publicly confirmed evidence supporting these claims.

Official reports identified the collision with the submerged Anemone Reef pinnacle as the direct cause of the sinking. No verified findings linked the accident to alcohol, negligence, or insurance fraud.

As with many maritime incidents, rumours have become part of the wreck’s local folklore over time, but they remain unconfirmed.

The King Cruiser Wreck Today

Today, the King Cruiser Wreck rests upright on the seabed between approximately 18 metres at the shallowest point and around 32 metres on the sand.

However, the wreck has changed dramatically over the years.

When the site first became popular with divers, many sections of the structure remained relatively intact and penetration dives were common. Over time though, the wreck has significantly deteriorated due to corrosion, storms, marine growth, and structural collapse.

Large sections of the ferry have now broken apart or collapsed entirely.

Because of this deterioration, penetration inside the wreck is no longer considered safe and is generally avoided by responsible dive operators.

A Challenging Dive Site

The King Cruiser Wreck is no longer considered a beginner-friendly dive site.

Conditions here can be challenging and often include:

• Strong and unpredictable currents
• Reduced visibility
• Surge and changing conditions
• Fishing lines and entanglement hazards
• Deeper dive profiles
• Sharp or unstable wreck structures

Visibility can vary significantly depending on season, weather, tides, and plankton blooms. On some days, visibility may be excellent. On others, divers may experience very limited visibility combined with strong current.

Conditions can become especially difficult around full moon and new moon tidal periods.

Because of these factors, divers visiting the King Cruiser Wreck should ideally:

• Hold an Advanced Open Water certification (or equivalent)
• Have recent diving experience
• Feel comfortable in deeper water
• Have strong buoyancy control
• Be confident diving in current and lower visibility conditions

At Aussie Divers Phuket, we generally recommend this site only for comfortable and experienced certified divers.

Marine Life Around the King Cruiser Wreck

Although the wreck itself has deteriorated over time, marine life around the site continues to thrive.

The King Cruiser Wreck now acts as an artificial reef supporting a huge variety of marine species.

Divers commonly encounter:

• Large schools of snapper
• Yellowtail barracuda
• Lionfish
• Scorpionfish
• White-eyed moray eels
• Trevally
• Groupers
• Fusiliers

The wreck structure also attracts many smaller reef species hiding throughout the collapsed sections and crevices.

Soft corals, sponges, and marine growth now cover much of the structure, giving the wreck an eerie but beautiful appearance underwater.

On lucky days, divers may even encounter larger pelagic species passing through the area including:

• Occasional whale sharks
• Leopard sharks
• Eagle rays
• Turtles

Artificial Reefs and Marine Conservation

One positive outcome from the sinking of the King Cruiser is the artificial reef ecosystem that developed around the wreck.

Artificial reefs often provide shelter, feeding areas, and breeding habitats for marine life. Over time, the King Cruiser has become an important marine habitat supporting biodiversity in the region.

While natural reefs remain critically important, wrecks like the King Cruiser can help reduce diver pressure on natural coral systems while also creating additional habitat for fish and marine species.

The site now serves as an interesting example of how marine ecosystems can adapt around man-made structures.

Diving the King Cruiser Wreck from Phuket

The King Cruiser Wreck is typically dived as part of a three-dive day trip from Phuket, often combined with nearby dive sites such as:

• Shark Point
• Anemone Reef

Because of the site conditions, dive operators will usually assess diver experience levels carefully before allowing divers onto the wreck dive.

For many experienced divers, the King Cruiser remains one of Phuket’s most exciting local dives due to its atmosphere, marine life, and constantly changing conditions.

Final Thoughts

The King Cruiser Wreck remains one of Phuket’s most iconic scuba diving sites and an important part of Thailand’s diving history.

However, this is no longer the relatively easy wreck dive it once was years ago.

Today, the site demands good buoyancy control, recent dive experience, and confidence in more challenging diving conditions.

For experienced divers, the King Cruiser Wreck still offers an incredible combination of history, marine life, and advanced diving adventure, all within reach of Phuket’s local dive boats.
