Dive Site Location & Key Facts
Dive Site Overview
P-31's origin dates back to 1969 as the East-German mine sweeper, Pasewalk. Following service in the German fleet, it became a Maltese Armed Forces patrol boat in 1992, assisting with rescue missions and anti-contraband operations.
In 2009, this 52 m (171 ft) long and 7 m (23 ft) wide craft was intentionally scuttled off Comino's west coast, specifically between Lantern Point and Cominotto, creating an artificial reef. Extensive preparation prior to submergence ensured diver safety; hazards like doors, windows, hatches, and engines were removed, and tight sections were welded shut.
The wreck lies nearly upright on a white sandy bottom, displaying a slight portside list. Its top is accessible at 7 m (23 ft) from the surface.
A maximum depth of 20 m (66 ft) is found at the bow, with the stern at 18 m (59 ft). These depths result from a slight shift during 2010-2011 storms.

Wave heights are also typically lower, averaging between 0.6 and 0.9 m (2-3 ft), contributing to smoother boat rides and better visibility. Conversely, the months from January to April and November to December see 'Moderate' dive scores, with higher average wave heights, increased wind speeds, and greater rainfall, ranging from 1.0 to 2.9 mm, which might affect surface conditions and underwater clarity.

Dive Experience & Conditions
Access to the P-31 wreck is exclusively by boat, typically involving a short ride from Mgarr Harbour or a scenic trip from Xlendi Bay. Upon arrival, the dive boat anchors close to the wreck, dropping a shot line to facilitate a controlled descent and ascent for divers. Conditions at the site are characterized by practically no current, which allows for relaxed exploration of the vessel. The wreck itself remains in good condition, inviting divers to explore its bridge, the shallower part at 12 m (39 ft), as well as the bow, stern, mid-section, and engine room. Divers often find ample time to circumnavigate the 52 m (171 ft) long patrol boat. Water visibility here is generally excellent, enhancing the experience for both photography and general observation.
Dive Difficulty & Safety Guidelines
The P-31 is regarded as a safe and accessible wreck dive, designed with diver safety in mind during its scuttling process. All potentially hazardous elements were removed or secured, making it suitable for certified divers of all levels, including those making their first wreck dive. While the wreck is well-preserved, divers should still exercise caution as the structure has been submerged for 15 years, leading to some natural weakening.
It's a popular site for advanced training, including wreck diving, Enriched Air Nitrox, and underwater photography courses. Divers should plan their bottom time carefully to manage no-decompression limits, especially when exploring deeper sections or considering multiple penetrations.
