Overview
British-built tugboat scuttled off Cirkewwa in September 1992 as Malta's first purpose-sunk dive attraction. The 40 m hull sits upright on a sand floor at 36 m, intact apart from the missing engine and propeller. The wheelhouse and mast top out near 20 m, giving recreational divers a layered profile from deck circuits down to the keel.
Briefing note
Deep recreational profile at 36 m — plan gas reserves, no-deco limits, and a safety stop carefully. A dive light helps inside the wheelhouse and bridge. Watch for ferry traffic on the surface near the Cirkewwa terminal.

Sources & methodology
How we summarise this
We aggregate confirmed occurrence records from GBIF and OBIS within a fixed radius of each dive site. Occurrence records confirm presence and reveal seasonality clustering, but they DO NOT measure per-dive probability — there is no eligible-effort denominator. We deliberately do not publish a numeric '% chance of sighting' from this data.
