Spanish cruiseship line Pullmantur is closing down its French operation.
Croisieres de France (CDF) will shut by the end of February next year as its parent focuses on Spanish and South American cruises.
"The entire French-speaking clientele will now be welcomed aboard the four ships of the company in a Latin atmosphere with Spanish sounds," Pullmantur said.
It had previously stopped French-language-only cruises.
A total of 33 jobs are at risk.
Royal Caribbean Cruises (RCCL) sold its majority stake in Pullmantur to Madrid-based Springwater Capital earlier this year.
It said it was forming a joint venture to offload 51% to Springwater, but would retain ownership of the 73,192-gt Sovereign (built 1987), the 47,427-gt Horizon (built 1990), the 73,937-gt Monarch (built 1991) and the 47,255-gt Zenith (built 1992).
