History & Geography

The Rubis submarine

The Rubis submarine was decommissioned on 4 October 1949 and deliberately scuttled on 31 January 1958 to prevent a Companion of the Liberation from being sent to the scrapyard torches. The wreck of the Rubis rests flat on the sand at a depth of 42 metres off Cap Camarat, at position 43° 11' N, 6° 42' E, between Cavalaire and Saint-Tropez.

Initially used as a sonar target by the French Navy, the Rubis wreck became a renowned diving site in the Mediterranean after being discovered by two divers from "L'Ideal", the boat of the Saint-Tropez Diving School, in July 1974.

The project

–42 metres on a single breath

Marc Dragon is taking on a rare and demanding challenge: freediving down to the wreck of the Rubis, resting at 42 metres depth off Cap Camarat. This dive, without breathing apparatus, requires physical, mental and technical preparation of the highest level, as well as a flawless safety setup. More than a sporting feat, this project tells the story of an intimate confrontation with depth, silence and one's own limits.

The documentary

The project is accompanied by a 20-minute film retracing Marc Dragon's entire journey: the birth of the idea, the project's development, the physical and mental preparation, and the dive itself. Structured in three acts — preparation, immersion, revelation — the film is written with the Oma agency and directed by Guillaume Voiturier, with distribution planned on France Televisions, Arte and specialised media.
