Key Dive Site Facts
Dive Site Overview
Zonqor Point in Marsaskala hosts the St. Michael and Tug 10, a pair of artificial reefs deliberately scuttled in May 1998. Both former tugboats from Valletta's Grand Harbour, they underwent extensive cleaning to ensure environmental and diver safety before becoming underwater attractions.
Known also as Iz-Zaghra or Number 10, the Tug 10 rests upright on a flat sandy bottom, its bows positioned against a reef base, with the stern about 3 m (10 ft) away. Approximately 50 m (164 ft) east from the bow of Tug 10 lies the St. Michael. Divers typically explore both wrecks together on a single dive.
Over time, both tugboats have become partially overgrown with corals and sponges, effectively transforming a previously barren seabed into a thriving habitat. An excellent opportunity exists here to practice wreck diving skills at medium depths, reachable via an easy 5-minute swim from shore.
Best Time to Dive
Diving conditions for the St. Michael and Tug 10 vary throughout the year, presenting different experiences depending on the season. Summer months, typically from June through September, are considered optimal, with dive scores rated as 'Good'. Air temperatures during this period range from 24.9-28.5°C (77-83°F), accompanied by minimal rainfall and significantly lower wave heights, averaging 0.7-1.0 m (2-3 ft). Calmer conditions are also supported by the wrecks' natural shelter from north-westerly winds. The winter months, from December to March, see 'Moderate' dive scores, with cooler air temperatures around 14.5-15.7°C (58-60°F) and higher average wave heights, sometimes exceeding 1.5 m (5 ft). Spring and autumn offer a favorable transition, maintaining 'Good' dive scores and more stable weather patterns, balancing comfort with fewer crowds.

Dive Experience & Conditions
Navigating the St. Michael and Tug 10 wrecks presents an approachable experience for certified divers. A relatively short swim from Zonqor Point accesses this shore-based site. While recreational depth limits are observed, with the deepest sections reaching approximately 21-24 m (69-79 ft), an Open Water Diver certification (minimum 18m) is considered suitable. However, an Advanced Open Water certification or equivalent is recommended to fully explore around the bottoms of both wrecks, granting more time at the maximum depths. Visibility in Marsaskala Bay, while generally good enough to easily locate the wrecks, is not consistently reported to be as clear as some other Maltese dive sites. Wrecks themselves are now largely encrusted with a variety of marine growth, creating an engaging environment.
Dive Difficulty & Safety Guidelines
While generally accessible, diving the St. Michael and Tug 10 requires adherence to standard safety protocols. Tugboats underwent a thorough cleanup prior to their scuttling, making them environmentally safe and suitable for diving without significant internal hazards from their operational past. Divers must be certified to a minimum depth of 18 m (59 ft) to safely enjoy this site. It's advisable to carry a compass to aid navigation between the two wrecks, as they lie roughly 50 m (164 ft) apart on the sandy bottom. Always plan your dive within no-decompression limits and monitor air consumption, especially when exploring both wrecks on a single dive. Local conditions, such as currents or wave action at the entry/exit point, should always be assessed before committing to a dive.
