Vietnamese Navy Patrol Boat – Nha Trang Wreck Dive

Site Overview

The Vietnamese Navy Patrol Boat wreck is a fascinating historical dive site in Nha Trang Bay, offering divers the chance to explore a genuine military vessel that has been transformed into a thriving artificial reef by decades of marine colonisation. The small patrol vessel rests upright on a sandy bottom at 18 metres, its superstructure and deck areas encrusted with dense growths of soft coral, sponges, and oysters that have completely transformed the military craft into a living reef ecosystem. Schools of batfish patrol the wreck's exterior in their distinctive formation flying, while lionfish have colonised the structure in impressive numbers, hovering near every suitable overhang and crevice. Large groupers and moray eels have claimed the interior spaces and darker recesses as their territory, creating an engaging wreck diving experience at manageable depths. The wreck's relatively small size and accessible depth make it an excellent introduction to wreck diving for Advanced certified divers, with limited penetration opportunities for those with appropriate wreck diving training. The historical significance of the vessel, a remnant of Vietnam's naval heritage, adds a cultural dimension to the diving experience that connects the underwater adventure to the country's rich military history. The wreck serves as an important artificial reef, demonstrating how human structures can support marine biodiversity when properly managed and protected.
