The IMOCA 60 class yacht PRB 4 was designed by Lauriot-Prévost and G. Verdier and launched in 2010 after being assembled by CDK Technologies based in Lorient, France.

[1] The hull was moulded in those of Safran and manufactured at the Larros Shipyard in Gujan Mestras under the direction of Thierry Elluère.

While sailing in the 2020-2021 Vendée Globe with French skipper Kevin Escoffier, who reported issues with a valve at the starboard foil on the 22 November, it suddenly sank on the 30 November, 2000 kilometers south-west of Cape of Good Hope.

Jean Le Cam was saved in the 2008-2009 Vendée Globe by none other than PRB 3 skipper Vincent Riou at Cape Horn.

[2] After having found Escoffier, Jean Le Cam lost visual contact with him as night fell.
