Two basic options for the trip, up the east edge of the
Bahamas or the Old Bahama Channel. I've done both and each has some pluses and minuses.
OBC is a little shorter, probably a little faster with a little boost from the
current. Down side, not many places to stop. PR, DR and
Haiti but north coast of
Haiti isn't the safest stop these days. Past Haiti the only options are
Cuba north coast and there's political issues with that. No places on the
Bahamas side.
Running the east side of the Bahamas is just slightly longer but has a lot more options on places to stop if you want or need. Shortest
route from there to Ft Lauderdale cut through the NE to NW Providence Channels.
