The freezer longliner's have been designed specifically for deep sea fishing. The vessels are expected to fish mainly for toothfish in the Southern Indian Ocean around Kerguelen and Crozet Islands.

The Ile Bourbon, Azamina, Albius and Cap Bourbon have all been finished and the final vessel in the series, the Ile de la Reunion, is due to be launched in May.
