MV Pal 2 Wreck, Port Moresby: a vibrant artificial reef

Dropping onto the MV Pal 2, you'll find the silhouette of a steel prawn trawler, intentionally scuttled in 1982 to create an artificial reef. The vessel, approximately 25 to 30 meters long, lies upright on a reef slope, oriented diagonally. Its keel rests at about 35 meters, with the main deck around 25 meters, providing a clear dive profile as you descend along its structure. The immediate impression is one of a successful habitat, where the industrial form of the trawler now supports a delicate and thriving ecosystem.

The masts of the MV Pal 2 are a prominent feature, rising to roughly 10 to 15 meters depth and heavily overgrown with dense black corals. These slow-growing organisms form intricate forests, offering shelter and hunting grounds for smaller reef inhabitants. Alongside the black corals, you'll find vibrant soft corals and clusters of Tubastraea trees, their polyps often extended, feeding on the plankton-rich water. This diverse coral growth transforms the wreck into a living sculpture, drawing your attention to every crevice and protrusion.

As you explore the decks and superstructure, you'll notice a significant quantity of fish life swirling in and around the wreck. Resident populations of cardinalfish, snapper, sweetlips, pufferfish, angelfish, and batfish make the MV Pal 2 a dynamic dive, with schools moving in unison. The wreck's structure provides ample hiding spots and foraging areas, making it a productive site for observing typical reef fish behavior. Keep an eye on the open water surrounding the wreck for larger pelagic species that occasionally pass by.

Among the more specific finds, you'll often encounter delicate red-lined anthias (Pseudanthias cooperi) flitting in colorful clouds near the coral formations. Their presence adds a vivid splash of color to the already rich tapestry of the wreck. With a keen eye, you also stand a good chance of spotting the Harlequin ghost pipefish (Solenostomus paradoxus), masters of disguise, often camouflaged against crinoids or soft corals. Finding these unique creatures is often a highlight, showcasing the specialized macro life that calls this wreck home.

The MV Pal 2 is not just a wreck; it's a multi-level site. The surrounding reef slopes extend from about 5 meters down beyond the wreck, allowing for varied dive profiles. This topography, combined with the wreck's upright position, means you can spend time exploring the shallower parts of the masts and superstructure before descending to the deeper keel. The site was purpose-sunk by local PNG diving pioneer Bob Halstead, specifically as a sport-diver attraction, and it remains one of Port Moresby's premier shipwreck dives.

Beyond the ghost pipefish, other elusive macro subjects like pygmy seahorses and leaf scorpionfish are regularly sighted, requiring a patient and sharp eye to locate them amongst the dense growth. The combination of large fish biomass and notable macro life makes the MV Pal 2 appealing for both wide-angle photography, capturing the overall wreck and its schooling fish, and macro photography, focusing on the intricate details of its smaller inhabitants. This dual appeal sets it apart as a versatile dive site.

The wreck's success as an artificial reef is evident in the sheer density and diversity of marine organisms that have colonized it over the decades. From the initial descent, the contrast between the steel structure and the vibrant life it now supports is striking. The MV Pal 2 offers a compelling narrative of how human intervention, when thoughtfully applied, can create thriving underwater ecosystems, providing a rich and engaging experience for divers of all interests.
