History of the King Cruiser Wreck in Phuket & Phi Phi

On May 4, 1997, the MS King Cruiser tragically sank off Thailand’s West Coast. This car ferry had been a mainstay for tourists and locals alike since its launch in 1969.

On a trip from Phuket to Phi Phi Islands, the ferry hit an underwater set of rocky pinnacles near Anemone Reef and became damaged beyond repair. Within two and a half hours, it had sunk completely – yet all 561 passengers were saved in time! Police patrol boats as well as several fishing vessels responded to the emergency call for help immediately, rescuing both Thai nationals and foreign tourists aboard.

Under great conditions, the ferry glided along its customary route through Anemone Reef – a region that was no stranger to these experienced captains. Nevertheless, despite this knowledge of what to expect in the region, a mishap still took place and left people questioning why it occurred. Consequently, there have been several baseless ideas as to what may have caused the accident.

About the King Cruiser car ferry

The ship’s size is 279 feet (85 meters) long, 82 feet (25 meters) wide, and has a height of approximately 100-ish feet (30 meters).

In the last two decades, this wreck has sadly deteriorated yet become a vibrant artificial reef that supports an abundance of aquatic life.

In 2003, the highest deck of the stern caved in, thus making it unsafe for anyone to enter. Previously, the shallowest part was close to 33 feet (10 meters), but due to its deteriorated condition, the tallest parts have collapsed. Besides the collapsed upper deck, the wreck remains largely in one piece.

Now, the wreck starts at 60 feet/18 meters.

Dive plan for the King Cruiser wreck

Divers usually use the mooring line in the north of the wreck down to about 59 to 72 feet (18 – 22 meters) to explore the bow and passenger deck level.

From there, divers swim around the wreck and explore the vessel as well as the marine life that calls the MS King Cruiser now its home.

On the deck level are many swim through opportunities, however, divers need to be aware of sharp objects and potentially collapsing structures. Additionally, camouflage scorpionfish might feel interrupted and could attack divers.

You can descend further and dive along the hull at depths of up to 108 feet (33 meters) on the high tide (98 ft/30 m on low tide). The average dive depth is usually between 72 and 85 feet (22 – 26 meters).

Reaching the south-end of the King Cruiser is the stern and car ramp. Above, at 60 feet (18 meters), lies the collapsed foredeck which is usually populated by snappers. The upper deck splits in half, providing more exciting exploration opportunities for divers.

On the ascent, you can explore the wheelhouse at the wreck’s peak and the highest point at 60 feet (18 meters).

Depending on the air consumption and the current, divers may not conduct the safety stop at the mooring line. Therefore, it’s important to stay together and fight the current during the safety stop and to use an inflatable diver down warning signal. Because of the dive site’s popularity and various exit points, there can be heavy boat traffic. Be extra cautious at the King Cruiser shipwreck dive site in Phuket.

Can divers explore the inside of the King Cruiser wreck?

For a secure, straightforward point of access, dive into the stern and traverse through the car decks. You’ll find machinery on deck, while inside are vehicle tires and an engine trolley. Furthermore, you can find passenger seats, as well as coffee tables, occupying its innermost crevices. 

Nitrox diving at the King Cruiser wreck

What certification is required to dive at King Cruiser wreck?

Only Advanced Open Water divers should take on the King Cruiser wreck dive due to its depth. It is essential to be aware of the current intensity as well, so if you haven’t yet reached an advanced certification level, it would be wise to consult with a professional diver before attempting this dive.
