we do it every June ...Marine Services...165 euros for a half day plus fuel..... for a 24 footer..the 31 footer we did once and the rate escapes me bu I think it was around 350 euros for half day
We did the 1/2 day, by seat, 42'Cat over to Ile Fourchue (sp) with them and it was great. You get a bit more time at sail going over and back which we enjoyed. If you take your own mask & snorkle down with you, you could fill an ice chest with provisions and carry your stuff on the path to Columbier as we did for the the day.
