This seems to be a small cargo ship of an overall length of about 40m. Recently a team found a plate of the shipyard and we can now presume that it's the wreck of the Petaling. The story says that it was sunk by a British submarine cruising the coasts of Phuket. The crew that survived the attack ended up drifting down to Kata Noi Beach, deported by strong currents. The story was related to us by an older Thai local who actually witnessed the attack and the final rescue of its crew. The vessel now lies off Kata Beach in 58m of water, flat on its keel with a slit list to port. The status of the ship is now pretty broken down. The Rudder and propeller (4 pan) are still their as if time could not harm them. This wreck for some reasons has a number of portholes lying around it that do not match the actual size of the boat. Like most of the wrecks, this one has been colonised by schools of fish, Morey eels now live in the numerous cavity's, and it's not rare to spot rays lying on the surrounding seabed.

The Vestal was a British Minesweeper of Algerine Class. Actually the very last Royal Naval vessel sunk during WWII. The identification is now 100% confirmed as the bell has been located and positively identifies the vessel. Algerine Class ship's displaced 990 tons for a length of 65m (225ft), 10.6m at the beam (35ft) and a drag of 3.2m (10.5ft). The motors where steam engines that could give a maximum speed of 16 knots and an autonomy of 4 500 miles at 11, 5 knots. The armament was made of one 4 inch canon, 4 20mm canons and a Hedgehog mortar. The crew was made of 8 officers and a crew of 99. The Vestal was hit by a Japanese Kamikaze plane and finally scuttled due to extensive damage on the 24th of July 1945. The ship now lies in 72m of water flat on its keel on a sandy seabed. The dive is a spectacular one. The amount of fish surrounding the wreck is fantastic. The ship is now covered with nets which gives it an exclusive mysterious theme but also builds up the danger of entanglement. This wreck definitely deserves a few dives to get around it. The general status of it is good.

The CP 1238 was a towed catamaran transport barge. The overall length was about 50m, 8m at the beam and 6m high. At the time of writing we have no history of this vessel. All that we know is that the barge apparently sunk about 6 years ago. It transported cars that now lie on the seabed, surrounding the wreck but too far to be seen on the same dive. The wreck now lies in 75m of water sitting straight up on a sandy seabed. The status of the wreck is excellent. The visibility can range from 10 to 30m depending on the tide and the surrounding fishing activities. On the front deck lays what could have been a life raft and closer to the stern two large 50cm diameter pipes and 4m long? Big Carangids, Tunas, Barracudas, Morey eels, Lion fish and Scorpion fish have now invaded the barge. If you are lucky the encounter of a Manta Ray would not be impossible in the region. The dive has no particular dangers except for the depth. A planning of 20-25min would be fine to get you all around it.

The HMS Vestal was thought to have been located back in 2002, recent identification of what was thought to be the sister ship turned out to be in-fact the HMS Vetsal. The wreck site we have been visiting for the last few year is in-fact confirmed as the HMS Squirrel as the bell of HMS Vestal was recovered and returned to the British Navy. This now clears up any confusion between the exact location of the two minesweepers. Dives are challenging but rewarding for those willing to hit the wrecks. Advanced Trimix certifications are required for diving on the minesweepers.

Type of Dive :		Pinnacle/Wall

Depth :		70+ meters

Hin Daeng is classified as on of the best dive sites in Thailand and offers one of the steepest and deepest drops. This massive limestone pinnacle protrudes by only a few meters above the surface. On the southwest side a vertical wall drops down to 50m. The pinnacle is covered with colourful soft corals and oysters, with huge beds of anemones in the shallower portions. Large stingrays have a tendency to rest on the sea bed. Large schools of barracuda, tuna and fusilier cruise around the rock and if you are lucky, you may get the visit of a reef shark. Hin Muang is definitely a world class dive site. This totally submerged rock is completely covered with hard, soft and antipatharian corals, sea fans and sea anemones. All the reef species found in the Similan can be seen here together with large oceanic visitors; whale sharks, manta rays, whitetips and silvertips.
