TUG2 Wreck, Sliema: Malta's accessible artificial reef

Dropping into the waters off Sliema, you'll find the TUG2 wreck a short fin-kick from the shore, a convenient entry point for a dive that doesn't demand a deep, dramatic descent. This 30-metre tugboat, intentionally scuttled in 2013, now rests upright on a sandy seabed, its bow partially embedded in the adjacent reef. The proximity to the coast allows for a relaxed entry and exit, setting the tone for a comfortable dive experience, whether you're refining your buoyancy or simply enjoying a leisurely exploration of a submerged structure.

The TUG2's structure has integrated with the marine environment, offering crevices and overhangs that invite closer inspection. As you trace the outline of its hull, you'll notice how the ocean has begun to reclaim the vessel, transforming its industrial form into a canvas for marine growth and shelter. A tropical storm in 2016 shifted the wreck about 30 metres, rotating it and driving the bow into the reef, adding a new dimension to the site while leaving the main structure largely intact and providing additional points of interest for exploration.

The wreck's open layout allows for safe swim-throughs of the wheelhouse and engine areas, provided you have appropriate training and maintain good buoyancy control. This feature makes the TUG2 a popular site for both scuba and freedivers, offering a chance to penetrate a wreck without extensive technical requirements. As you navigate these internal spaces, the interplay of light and shadow creates an engaging environment, revealing how marine life has adapted to these sheltered confines.

Keep your eyes peeled for the resident Civette de mer (Catafaucia aquilonia), often found seeking refuge within the TUG2's framework, a key highlight of this particular site. Beyond this, the wreck hosts a variety of marine life including barracuda, damselfish, bream, and wrasse, which can be seen schooling around the structure. Groupers, moray eels, and octopuses also inhabit the wreck, using its nooks and crannies for shelter, while nudibranchs, sea stars, and sea cucumbers can be found on the hull and surrounding seabed.

The site is generally sheltered from wind and current, making it a reliable option even when westerly winds are strong elsewhere. Water movement is usually mild, allowing for detailed observation of the wreck and its inhabitants. While summer boat traffic in Exiles bay can be high, this primarily affects surface navigation rather than creating strong underwater currents, so plan your surface swim accordingly, especially if accessing from shore.

What truly defines the TUG2 wreck is the intimate scale of the dive, encouraging detailed observation rather than covering vast distances. You'll have ample opportunity to slow down, refine your buoyancy skills, and appreciate the finer details of the marine life that have made this compact wreck their home. This focus on detail, combined with its accessibility, makes the TUG2 a valuable site for building confidence and honing skills in a real wreck environment.
