This is an excellent wreck dive, once the most popular shipwreck as it was the first purposely sank and prepared for divers, in the years since it has attracted so much character and coral growth and some very interesting marine life. Featuring great swim-throughs to explore, with the engine room, corridor slips and the bow doors ‘black hole’ its a must-have entry in the logbook.

Macro life covers the deck with Nudibranchs Seahorses and of course scorpion fish too! You are likely to bump into a giant hawksbill sea turtle or two also as you explore the massive deck areas. Pattaya Dive Centre instructors have thousands of dives on the wrecks between them so you are guaranteed perfect professional guides to show you around including the shark hole where bamboo sharks regularly lay if you know and have the experience to find them!.

HTMS Mataphon is a Mark VI Landing Craft Tank and is situated 45mins from Pattaya Beach outside the island bay of Hard Nuan, south of Koh Larn island.

The craft is already teeming with life from Nudibranch and dresser crabs to some larger residents such as Grouper and Blues Spot Sting Ray, the occasional school of Bat fish hang around and play with the divers also.

The Hardeep ship originally known as the SS Suddhadib was attacked and sunk by British Allied bombers in the latter part of World War II. Originally, she had a long service history before the war as both a passenger and cargo-ship before she was commandeered by the Japanese army to run supplies to Thailand where they were building the railway linking the country to Burma. The shipwreck is located just off Samae san, and is 64-metres long and lies on her starboard side literally only a few hundred metres from Koh Chuang

Her hull is largely intact and there is access to the engine room where you can see the huge crankshaft you can also swim though the cargo hold which is known as the Cathedral because of the shafts of light that pour through the vast interior of this area.

Time has taken its toll on the superstructure of the Hardeep Wreck and penetration is becoming risky, but it is possible to swim along the deck, through the remains of the superstructure from end to end, this makes a great dive. To the trained eye it’s still possible to identify the remains of the funnel and also the foremast. A short swim, following the line of the funnel, will bring you to an none detonated 1000lb bomb sitting upright in the sand. There’s certainly a lot to be explored just inside. It seems to me that every time I dive into this wreck there’s more to see. Certainly a must for any shipwreck enthusiast. After nearly 60 years nature has worked her magic on the shipwreck and it is home to angelfish, batfish, groupers, stingrays, barracuda, wrasse, butterfly fish, crabs, and nudibranchs.

The Bremen Wreck is one of Pattaya’s most intriguing dive sites, offering a fascinating look into Thailand’s maritime history. Originally a German freighter, the vessel was reportedly scuttled in the Gulf of Thailand under mysterious circumstances. Today, it rests at a depth of approximately 24 meters, with the shallowest sections around 16 meters, making it accessible to Advanced Open Water divers and adventurous Open Water divers under supervision. The wreck has become an artificial reef, attracting an abundance of marine life and providing divers with an exciting mix of history and underwater exploration.

While the ship’s structure has deteriorated over the years, Bremen Wreck still offers plenty of opportunities for exploration, including open cargo holds, broken masts, and scattered remnants of its original framework. Unlike the more prepared wrecks in Pattaya, Bremen has a more natural decay, giving it a rugged and authentic shipwreck feel. Divers must be mindful of sharp metal edges and shifting sand, but the wreck’s layout makes for an exciting yet manageable dive for those with proper training.

Divers can expect to encounter schools of barracuda, curious batfish, and even elusive seahorses along the hull. The site is also popular for night dives, where divers can witness hunting moray eels and bioluminescent plankton. Whether you’re seeking an eerie yet beautiful dive experience or an exciting addition to your wreck diving logbook, the Bremen Wreck is a must-dive site in Pattaya.

Twin Shipwreck Dive Site – Samae San, Pattaya, Thailand

The T-Wrecks — the recently sunken T.94 and T.95 patrol ships — have rapidly become one of Pattaya’s most exciting new dive sites. These identical sister vessels, now resting on the seafloor near the Samae San Islands, offer divers a rare opportunity to explore two purpose-sunk wrecks within just 100 meters of each other. Their transformation from naval defense ships into thriving artificial reefs has added fresh energy to Thailand’s wreck diving scene.

Once part of Thailand’s coastal defence fleet, both ships were constructed in Thailand as part of King Rama IX’s initiative to strengthen national naval independence. After serving for over 30 years, the Thai Navy officially decommissioned and sank the ships in September 2024, turning them into new marine sanctuaries and exploration zones for divers of all levels.

• Shipwreck Location: Same San Marine Park
• Wreck Site Access – 2 Buoy lines to descent to each wreck
• Max Depth – 22m
• Wreck Length – Approx. 35m
• No Deco Limits (Dive Tables) – Normal Air: 30 mins / EANx up to 50 mins
• Nitrox Computer Dives – Extends bottom time significantly
• Safety Stop Procedures – Mandatory 3-min stop at 5m
• Common Aquatic Life – Nudibranch, Turtles, moray eels, True Stonefish, stingrays, and Eagle Rays

Resting at depths of 18 to 30 meters, the T-Wrecks are suitable for both Advanced Open Water divers and supervised Open Water divers. Their relatively intact structures feature accessible control rooms, open corridors, and spacious engine compartments, allowing for safe penetration and skill development.

Unlike older, deteriorated wrecks, the T-Wrecks provide a clean, stable dive with high visibility and minimal hazards, making them ideal for training dives, underwater photography, and eco-conscious exploration.
