The 38-year-old was enjoying the sunshine on French friend and magazine boss Jean Yves Le Fur's boat. The model was seen laughing and joking with friends while topping up her tan, reported Sun Online.
Moss was pictured in just a pair of black bikini bottoms sitting on the deck beside a speaker which was pumping out tunes.
The holiday spot seems to be a favourite of Moss, as she jetted there this time last year for a break on a yacht.
Moss has a 10-year-old girl Lila Grace Moss Hack with editor Jefferson Hack and is currently married to Jamie Hince.
