Key Dive Site Facts
Dive Site Overview
HTMS Khram, a substantial 62-meter (203 ft) long former US Navy landing ship, rests upright on the seabed off Pattaya, forming a significant artificial reef. This vessel, decommissioned and prepared by the Thai Navy, sits approximately 300 meters from Koh Phai.
Divers find the top of the wreck at about 15 m (50 ft), extending down to its max depth of 30 m (100 ft) at the seabed. Many large holes were intentionally cut throughout the ship, allowing for penetration dives that often remain within natural light. Near the highest point, the bridge offers simple and safe entry, though some original fittings like portholes and the telegraph are no longer present.
Further aft, an engine room provides a complex, naturally lit environment with numerous pipes and gauges, though main engines have been removed. A largely flat main deck area reflects its original purpose of carrying tanks and troops.
Best Time to Dive
Visibility generally influences the optimal time for diving the HTMS Khram, which is accessible year-round. The most favorable conditions typically occur from November through February, when dive scores are consistently rated 'Excellent'. During these months, average air temperatures range from 26.6°C (80°F) to 27.7°C (82°F), with minimal rainfall, averaging less than 1.0 mm. Water temperatures around the wreck are quite comfortable, usually staying between 27-30°C (81-86°F), supporting good visibility often ranging from 15 to 30 meters. As the year progresses into March and April, dive scores remain 'Good', with air temperatures increasing slightly to nearly 30°C (86°F) and rain remaining low. While conditions are generally good throughout the year, the rainy season from May to October can introduce more precipitation, potentially affecting surface conditions.

Dive Experience & Conditions
Currents around the HTMS Khram can vary, influencing the dive experience; strong currents are not consistently reported. Considered an advanced dive, it presents challenges due to its depth and opportunities for penetration. Expect consistently warm water temperatures, typically between 27-30°C (81-86°F), contributing to comfortable dives. Visibility often ranges from 15 to 30 meters, depending on recent weather and marine activity. The wreck sits at an average depth of around 22 meters, with its deeper sections reaching the seabed at maximum recreational dive limits. Purposeful sinking and preparation of the vessel mean it's an accessible wreck for divers with appropriate training, including those undertaking advanced or wreck diver certifications.
Dive Difficulty & Safety Guidelines
Divers planning to explore the HTMS Khram should be aware of specific considerations, particularly within penetration areas. While the ship was prepared for diving, with most armaments and oil removed, certain risks remain. Inside the side corridors and engine room, caution is advised to avoid kicking up silt, which can quickly lead to a complete silt-out and reduced visibility. Some rooms, particularly ammo storage areas, may still have large steel watertight doors that could inadvertently close. Furthermore, the engine room features overhanging ledges where divers could potentially become trapped if not careful. For any penetration beyond the open deck, proper wreck diving certification and experience are essential, ensuring divers are prepared for the unique challenges of an overhead environment.
