T94 and T95 Shipwrecks Dive Samae San: A Powerful New Chapter in Pattaya Wreck Diving
The T94 and T95 Shipwrecks Dive Samae San is quickly becoming one of the most talked-about additions to scuba diving Pattaya. These two decommissioned Royal Thai Navy patrol ships—T94 and T95—were purposefully sunk off the coast of Chonburi to form a thriving new artificial reef and underwater heritage site. Nestled between the scenic islands of Koh Chuang and Koh Chan, this Pattaya shipwrecks dive site offers divers the chance to explore not just history, but a living reef in the making.
For those passionate about Thailand shipwrecks, this new dive site in Samae San shipwrecks Pattaya region represents the perfect fusion of naval legacy and marine biodiversity. Whether you’re a seasoned wreck diver or an underwater photographer looking for your next dramatic backdrop, this twin-wreck site is quickly becoming an essential stop on the scuba diving Pattaya map.
The History of T94 and T95 – Guardians of the Gulf Turned Reef
Before becoming iconic Thailand shipwrecks, the T94 and T95 served for nearly four decades as proud coastal patrol vessels in the Royal Thai Navy. Part of the legendary “Tor.91” class—affectionately known as the “Father’s Boats”—these ships were commissioned as part of King Bhumibol Adulyadej’s vision to strengthen Thailand’s self-reliant naval capabilities.
Commissioned in the early 1980s, both T94 and T95 were active participants in national defense along the Gulf coastline. At just over 34 meters long, these ships were compact but fast, built for coastal monitoring and response operations. After being officially decommissioned in 2019, they were carefully preserved by the navy with one goal in mind: to become part of the Samae San shipwrecks Pattaya initiative.
Instead of being scrapped, the Royal Thai Navy chose to repurpose them into an artificial reef and dive site, contributing to both marine conservation and scuba diving Pattaya tourism. This transformation from warships to underwater sanctuaries is now inspiring divers from around the world to experience the T94 and T95 Shipwrecks Dive Samae San site for themselves.
These two vessels now rest together on the ocean floor, side by side, marking their second life as part of the growing ecosystem of Pattaya shipwrecks—preserving not only steel and bolts but also the stories of those who once sailed aboard.
The Sinking Ceremony – Honoring Service, Creating Legacy
The transformation of the T94 and T95 Shipwrecks Dive Samae San site began with an emotional and symbolic ceremony held by the Royal Thai Navy. On August 30, 2024, senior officers, navy veterans, and members of the conservation community gathered at the Sattahip Naval Base to bid farewell to these two historic vessels.
As part of Thailand’s growing initiative to create purposeful Thailand shipwrecks for eco-tourism and reef restoration, the ceremony included traditional offerings, floral garlands, and a moment of silence to honor those who once served aboard T94 and T95. The sinking was more than a disposal—it was a reverent retirement.
Just days later, on September 3, 2024, the ships were towed out into the Gulf of Thailand, near the island pair of Koh Chuang and Koh Chan—an area now central to Samae San shipwrecks Pattaya development. With naval engineers guiding the descent, the vessels slipped below the surface upright, resting perfectly in position to become the centerpiece of Pattaya shipwrecks exploration.
This carefully planned act wasn’t just a nod to heritage—it marked the launch of a scuba diving Pattaya milestone. The T94 and T95 were officially reborn as a twin-wreck artificial reef, forming a cornerstone of what the Navy proudly calls an “Underwater Learning Park.”
Divers now descend upon these wrecks not just for adventure, but to be part of something deeper: a story that connects national history, marine conservation, and the thriving tourism scene anchored in the heart of T94 and T95 Shipwrecks Dive Samae San.
Location and Structure – Where the T94 and T95 Shipwrecks Rest
The T94 and T95 Shipwrecks Dive Samae San site lies in the crystal waters off Thailand’s eastern seaboard, nestled between the twin islets of Koh Chuang and Koh Chan, just south of the mainland in the Samae San shipwrecks Pattaya zone. This strategic placement by the Royal Thai Navy offers divers not only ease of access but also dramatic topography and current-fed biodiversity.
Both vessels were intentionally sunk upright in a parallel formation on a sandy channel bottom—just 30 meters apart, making it effortless for experienced divers to explore both wrecks in one dive. The wrecks now form a striking underwater corridor, clearly visible from one another on days of good visibility.
Their structure remains largely intact. Each patrol ship measures around 34 meters in length, with decks beginning as shallow as 12 meters and extending down to a maximum seabed depth of about 28–30 meters—making the site ideal for advanced-level scuba diving Pattaya trips. For divers trained in deep or wreck specialties, the layout offers accessible entry points into control rooms and passageways, while casual explorers can enjoy the towers, rails, and hull exteriors without needing to penetrate.
Their upright position enhances safety, orientation, and photography opportunities, earning the site a rising reputation among fans of Thailand shipwrecks. Dive centers in Pattaya have even begun referring to the site as the “Twin T Wrecks” due to the unique side-by-side layout.
From their rusting anchors to the commanding silhouettes of their bridges, these wrecks now stand as monuments under the sea—living relics of the Royal Thai Navy, now repurposed into vital habitat and essential new stops along the Pattaya shipwrecks circuit.
Dive Conditions and Safety Tips – What to Expect at the T94 and T95 Shipwrecks
If you’re planning your first T94 and T95 Shipwrecks Dive Samae San experience, understanding the conditions will help you get the most out of your descent. This twin wreck site sits in a channel where currents, visibility, and depth work together to shape an exciting but demanding dive—perfect for those who want more than just a coral reef tour.
Depth and Profile:
The wrecks rest between 26 to 30 meters on the seabed, with their superstructures rising to around 12–18 meters, offering multiple levels of exploration. Because of this depth, the Samae San shipwrecks Pattaya area is best suited for divers holding an PADI Advanced Open Water certification or equivalent. Penetration is not required to enjoy the wrecks, but certain openings and corridors are available for those trained in wreck or deep specialties.
Visibility:
Water clarity ranges from 5 to 30 meters, heavily influenced by tides and plankton blooms. On optimal days—especially in the dry season (November to April)—divers have reported visibility so good that both ships can be seen from a distance. As with most scuba diving Pattaya sites, it’s best to dive early in the day and check in with local operators for current conditions.
Currents:
The channel between Koh Chuang and Koh Chan can produce moderate to strong currents, particularly around tide changes. Dive operations often time visits for slack tide, but it’s wise to bring a surface marker buoy (SMB) and be ready for drift conditions. The wrecks provide solid shelter on the lee side for current breaks.
Safety Considerations:
- Always dive with a local, licensed divecenter, as this zone is still under naval regulation.
- Use a dive computer and monitor your no-decompression limits closely, especially if you plan to explore both wrecks in one dive.
- Carry a torch: even though penetration isn’t required, peeking into compartments and illuminating marine life greatly enhances the experience.
- Respect the wrecks: as artificial reefs, they are developing ecosystems. Avoid touching coral growth or disturbing marine life.
Access:
This is a boat-only site, with day trips departing from Samae San Village or Pattaya. Trips often combine these wrecks with other Pattaya shipwrecks like Hardeep, creating a full-day adventure for wreck lovers.
From conditions to conservation, the T94 and T95 Shipwrecks Dive Samae San offers a deeper dive—literally and figuratively—into the thriving underwater world of Thailand shipwrecks.
Marine Life Flourishing on the Wrecks – A Reef Reborn in Samae San
In just a short time, the T94 and T95 Shipwrecks Dive Samae San site has gone from bare steel to bustling reef. Artificial wrecks often attract marine life rapidly, and these two patrol boats are no exception. Since their sinking in late 2024, they’ve become a magnet for biodiversity—earning the site its place among the most exciting new Thailand shipwrecks.
What You’ll See:
Early dive reports from local operators and instructors describe schools of fusiliers, batfish, and juvenile barracudas already circling the towers and bridges. On the sand surrounding the wrecks, divers frequently spot blue-spotted stingrays, Jenkins whip rays, and lizardfish blending into the seabed. These sightings underscore the site’s value to both divers and marine biologists tracking reef development.
Inside and Around the Hulls:
The open corridors and shaded areas within the T94 and T95 have attracted moray eels, grouper, and even giant pufferfish. Swim-throughs around the command decks and wheelhouses provide both hiding spots for critters and thrilling moments for photographers. On more than one occasion, divers reported the visit of a sea turtle, casually cruising through the corridors as if inspecting the navy’s newest reef.
Coral Colonization:
Though the wrecks are still young, they’re already showing signs of colonization. Algae, barnacles, and soft corals have begun to take hold on the outer surfaces. Given the nutrient-rich waters of the Samae San shipwrecks Pattaya region, it won’t be long before these structures support a colorful array of sponges, gorgonians, and eventually hard corals. Divers with macro lenses may also find nudibranchs, blennies, and pipefish as the wrecks mature.
Ecosystem Value:
This artificial reef is already acting as a refuge for juvenile species, a nursery zone, and a feeding station. It also helps ease pressure off natural reefs in nearby areas, aligning perfectly with Thailand’s marine conservation goals and reinforcing the ecological merit of the Pattaya shipwrecks program.
Whether you’re passionate about underwater photography, fish ID, or just witnessing the ocean’s ability to reclaim steel and turn it into life, scuba diving Pattaya just got an upgrade—with the T94 and T95 Shipwrecks Dive Samae San leading the charge.
Planning Your Dive Trip – What You Need to Know
If the T94 and T95 Shipwrecks Dive Samae San are now on your must-dive list—and they should be—here’s exactly what you need to plan the perfect trip. These twin wrecks are not only one of the freshest Thailand shipwrecks, they’re also one of the most accessible and exciting new additions to scuba diving Pattaya.
Getting There
The wrecks are located off the coast between Koh Chuang and Koh Chan in the Samae San shipwrecks Pattaya zone, roughly a 45–60 minute boat ride from Pattaya or a shorter trip from Sattahip/Samaesan pier. Trips typically depart early morning and include 2–3 dives. You’ll need to book through a dive center with authorization to access the military-controlled waters.
Certification & Experience
Due to a max depth of 28–30 meters and potential for moderate current, divers are strongly recommended to hold an PADI Advanced Open Water certification or equivalent. Many dive centers now offer Deep and Wreck Diver Specialty courses that include dives on the T94/T95 wrecks. Some operators also allow Open Water divers with instructor supervision, but may limit depth.
Best Time to Visit
The dry season (November to April) offers the most stable surface conditions and the clearest visibility—often 15–30 meters. The monsoon season (May to October) brings nutrient-rich waters that attract fish but may reduce visibility and bring choppier seas.
What to Bring
- Dive computer: Essential for depth/time tracking
- Surface Marker Buoy (SMB): Required for safety in current
- Torch: For inspecting compartments or low-light corners
- Wetsuit: 3mm–5mm recommended; water temp ranges from 26–30°C
- Camera: These are some of the most photogenic Pattaya shipwrecks
What to Combine It With
Many trips pair the T94 and T95 Shipwrecks Dive Samae San with a dive on the historic Hardeep wreck, or coral reef sites like Shark Fin Rock. This makes for a well-rounded day of exploring both Thailand shipwrecks and natural reef systems, perfect for divers with varying interests.
Environmental and Tourism Impact of the T94 and T95 Shipwrecks Dive Samae San
The sinking of the T94 and T95 wasn’t just a boost for divers—it was a strategic move in Thailand’s long-term marine conservation and sustainable tourism goals. The T94 and T95 Shipwrecks Dive Samae San site now represents a model for how purpose-sunk wrecks can support both ecology and economy.
From an environmental perspective, these ships form the foundation of a rapidly developing artificial reef. By relocating diver traffic away from overused coral zones, the wrecks help protect fragile ecosystems while offering a new structure for marine life to colonize. Within weeks of submersion, the site began drawing in fish, rays, and reef-building organisms. Over time, these wrecks will become key microhabitats, contributing to reef resilience across the broader Samae San shipwrecks Pattaya region.
From a tourism perspective, this dive site immediately raised the profile of scuba diving Pattaya. As one of the few newly opened wrecks in the Gulf of Thailand, the twin ships have already brought a surge of interest from advanced divers, photographers, and even students taking specialty certifications. Dive operators are now building custom tours around these wrecks, combining them with other Pattaya shipwrecks and reef sites to offer more variety and value.
The broader impact extends to local communities. With Samae San village and Sattahip already serving as gateway ports, the increase in dive traffic has supported local boat crews, dive guides, accommodations, and small businesses. By promoting this new site as both a diving highlight and a conservation success, the Royal Thai Navy has reinforced the role of Thailand shipwrecks in sustainable marine tourism.
The result is a win-win: marine biodiversity is gaining new protected space, and the Pattaya dive industry has a fresh, exciting story to tell. The T94 and T95 Shipwrecks Dive Samae San are more than wrecks—they’re part of a national vision to align environmental responsibility with underwater adventure.
How T94 and T95 wrecks Complement Pattaya’s Iconic Shipwrecks
The T94 and T95 Shipwrecks Dive Samae San site is not here to replace Pattaya’s beloved wrecks—it expands the underwater portfolio in a powerful way. Together with historic and purpose-sunk sites like the Hardeep, HTMS Khram, HTMS Kut, HTMS Mataphon, and the rugged Bremen Wreck, these twin patrol boats complete a wreck diving circuit that makes scuba diving Pattaya one of the most varied and rewarding experiences in Thailand.
The Hardeep wreck, sunk in 1945, is a must-visit for those drawn to wartime history and deeper wreck penetration. It’s one of the oldest and most famous Thailand shipwrecks, offering a dramatic structure resting on its side, now heavily encrusted in marine life. Diving Hardeep gives a visceral sense of time and decay—ideal for seasoned wreck explorers and history lovers.
The HTMS Khram and HTMS Kut, both decommissioned navy ships intentionally sunk for reef building, have become reliable training grounds for deep and wreck diver courses. Their accessibility from Pattaya’s main beach makes them perfect for local trips, offering upright structures, wide swim-throughs, and vibrant fish life. For many divers, these are the very first Pattaya shipwrecks they explore, creating unforgettable entry points into the world of wreck diving.
The HTMS Mataphon, the most recent addition before T94 and T95, lies at moderate depth and is ideal for beginner wreck divers or photography-focused dives. Its smaller size and clean structure make it a popular second or third dive of the day—especially for those who enjoy relaxed wreck exploration in shallower waters.
Then there’s the Bremen Wreck—a challenging, current-swept site known for its real decay, eerie atmosphere, and raw structure. Unlike purpose-sunk vessels, the Bremen is a natural wreck, offering a gritty, immersive experience that serious wreck enthusiasts appreciate. It stands in stark contrast to the symmetry and order of Khram or Kut, making it a thrilling highlight for advanced divers in Pattaya.
Now enter the T94 and T95, adding a new story to this legacy. Recently scuttled and resting upright just 30 meters apart, they form a twin-wreck site rarely found elsewhere in Thailand. Their location in the Samae San shipwrecks Pattaya zone means cleaner water, often better visibility, and slightly different marine ecosystems. For those looking to complement their previous dives on Khram or Hardeep, this new site offers something fresh—new steel, new coral beginnings, and new opportunities for photography, training, or just adventure.
Each of these wrecks tells a different story. T94 and T95 are the newcomers—but they don’t compete. They enhance. They invite. Together, these sites showcase exactly why scuba diving Pattaya continues to grow: history, biodiversity, training value, and now, a twin wreck experience that completes the picture for divers seeking the full Thailand shipwrecks journey.
Safety, Ethics, and Reef Etiquette at the T94 and T95 Shipwrecks Dive Samae San
Wreck diving is one of the most thrilling experiences in the ocean—but it also demands mindfulness. The T94 and T95 Shipwrecks Dive Samae San are not just adventure sites; they are also living reefs, training zones, and cultural memorials. As such, divers share a responsibility to protect the integrity of the wrecks, preserve the surrounding marine life, and respect the rules that keep all underwater visitors safe.
Master Your Buoyancy First
The number one rule for exploring any Thailand shipwrecks is precise buoyancy control. The structures of T94 and T95 are still developing their marine growth, and even a minor fin kick or unintended contact can stir up sediment or damage delicate coral beginnings. Before approaching the wrecks, make sure your trim and buoyancy are fully neutral. Hover, don’t kneel—especially near the sandy bottom between the ships.
No Touching, No Taking
These Pattaya shipwrecks are historical artifacts, marine nurseries, and artificial reefs. Touching the hulls, railings, or equipment can not only degrade the metal but also disrupt colonizing organisms. More importantly, taking “souvenirs” from the site is illegal and undermines the purpose of preserving these wrecks for future generations. The best treasure you can take from scuba diving Pattaya is the memory—and maybe a great photo.
No Penetration Without Proper Training
Both wrecks feature cutouts and openings, tempting divers to explore inside. However, wreck penetration comes with real risk: entanglement, disorientation, and silting. Only attempt interior entry if you’re certified in wreck diving, equipped with a reel or guideline, and briefed on the specific layout by your guide. Otherwise, enjoy the stunning exteriors and peek safely into rooms and compartments with a torch.
Follow the Lead of the Local Guides
Dive centers with access to the Samae San shipwrecks Pattaya site are familiar with current patterns, depth profiles, and naval restrictions. Always follow their briefing, maintain buddy contact, and surface slowly with a safety stop at 5 meters. Consider carrying a surface marker buoy (SMB) to alert boats during ascent, especially in areas where currents can shift.
Be a Guardian, Not Just a Guest
The T94 and T95 Shipwrecks Dive Samae San are part of a larger effort to balance marine tourism with reef restoration. Every diver plays a role. By treating the site with care—staying off the wreck, keeping fins off the sand, and never disturbing wildlife—you become part of the success story. You help turn this artificial reef into a thriving ecosystem and a top-tier example of sustainable wreck diving in Thailand.
