Published ownership

Lorenzo Segalini (historical published part-owner) [4]

Basis: The April 2018 firsthand report explicitly calls captain Lorenzo a part-owner. His surname and continuing association are corroborated by the April 2024 fundraiser co-organized by Lorenzo Segalini and written by former crew. This is a dated published part-ownership claim, not current registered title.

As of: 2018-04

Ownership and the advertised operator are separate roles. Historical records remain dated claims.

Research notes and uncertainties

Website lists historic vessel facts and Sudan itineraries; no contemporary sailing verified. Italian flag described for 1984 conversion, not asserted as current flag.
The distinctive Don Questo name, 1964 construction, passenger conversion and approximately 7 m breadth link the IMO record to the Sudan dive vessel. The operator gives overall length 33.5 m, versus database 31.22 m; the measurement difference remains unresolved. No current MMSI or flag is assigned from historical photos.
A database radio identity is not confirmation of live AIS reception or current service. No database coordinates or stale position timestamps are promoted to live tracking.
The part-owner claim is historical (April 2018), with identity corroboration in a 2024 first-party fundraiser. No current flag, MMSI or operational status is inferred from old documents or the 2025 reopening advertisement. The 1998 refit is the documented conversion, not a claim that no later work occurred.

Not yet verified: Operator, Crew, Hull, Flag, MMSI, Callsign.
