Melbourne a great place to sail and live
I echo Ron's posting. We live across from Telemar Bay Marina and have been sailing this area since 1966. 4' draft is no problem, my current boat draws 4' 9" and although there are many areas in the Indian River with less than this, with some experience, and discussions with others, you really have few limitations. Access to the Bahamas is good and while it takes a few days to get there, the Keys are achievable. The ECSA that Ron mentioned has cruising and racing activities. This is a good place to sail and live!
