Greetings All,My wife and I honeymooned in the BVI's last November and I was instantly intrigued by how many people travel and stay on sailboats down there. I had sailed a Sunfish quite extensively when I was in my teens and took sailing courses. I'd long had a desire to have a cruiser sailboat some day, and our trip to the BVI's re-kindled that dream.We bought a Mac 25 about a month ago, we are sailing it on the weekends at one of the larger reservoirs in NE Oklahoma and I am learning all I can from a variety of books and learning the handling characteristics and experimenting with sail trim. I've had one of my more experienced buddies go out with us, and I've got another who is a USCG certified captain and instructor who is going to be going out with us.I've found web sites like Conch Cruisers who sail to the Dry Tortugas and Bimini and I'm looking forward to the day to go on such excursions.My question is, what in the opinion of other sailors on here is a requisite amount of fresh-water experience prior to going off-shore (i.e. coastal sailing and eventual passage making)?
