Jeez, worrying about fuel cost and time to go that far as the first concerns sounds like a major accident waiting to happen.
this reminds me of a time when a friend of mine suggested that he would be free at 1900 in Cannes and we could meet at 1915 to pick him up off the public dock to have dinner... only we were sailing from Marseilles that day and the wind was blowing out of the east F7-8.
Sailing and even open sea powerboating is not a deadline based activity, even less so for an inexperienced captain & crew.
Forget message boards for a few months. Go to the local yacht club and inquire about sailing training - coastal, offshore, get your wet weather gear and spend 6-8 weeks going thru the first steps of training to understand basic sailing, navigation, rules & security, and first aid.
THEN come back and get the details on such a trip.
Harsh, but someone with no sailing experience looking at such a trip is just asking for trouble, the type of trouble that can have more than just material consequences.
