The Don Questo was built in Selby, England in 1964 as a trawling vessel. In 1984 she was transformed into an oceanographic research vessel under the Italian flag. In 1991 she had a complete overhaul but it was in 1998 that the Don Questo was fitted out to become a diving liveaboard ship. New toilets and cabins were added, the restaurant and kitchen were renovated, state of the art compression systems were installed and a hydraulic platform was built. The diving area is arranged as a long bench so that you can put your cylinder in its slot, your dive gear is stowed neatly away underneath and the compressor system runs along this bench so there is no need to move the cylinders for a fill. The Don Questo is the only ship running in Sudan that has a recompression chamber on board.
