Daytrip yacht charter on Corfu?

Hi all,

I'm helping to plan a friends wedding on Corfu and the couple are wanting to charter a yacht (10-15 m/30-50 ft.) for a day to take the bridal party around the island. (They are aware of the likely price tag for what's basically a catered booze cruise!) The usual googling hasn't yielded many reputable looking options, and instead a lot of smaller craft charters. Has anyone here tried something like this on Corfu? Alternatively, might anyone have any local contacts who might have connections?

Thank you!
