The club was founded in 1984, following the opening of the Petit Port Leisure Center, a sports complex featuring a brand new ice rink.

[1] Its nickname is a reference to the corsairs, privateers sailing on behalf of the French crown from the Middle Ages to the early 19th century, a number of which were based in Nantes.

[10] The Conseil général de Loire-Atlantique pledged its support and the club obtained a court judgment allowing it to continue its activities.

For the Division 2 playoffs and ensuing offseason, recently elected president Dogémont summoned longtime collaborator Gélinas—then between jobs in Basel and Lausanne[16]—back to the fold to serve as a special coaching consultant.

[22][23] In 2015, the Corsaires introduced an unusual partnership with Hellfest, a major heavy metal music festival held every June in Clisson.

[25] In 2019, the festival staged a song contest to find the club's anthem, with Sepultura vocalist Derrick Green and Biohazard guitarist Billy Graziadei among the jury members.
