If heading for Bimini I used to leave from Miami staging out of no name harbour.
N.B. If going to Bimini make sure you time things to arrive with good light for an EYEBALL nevigation entrance. At 3.5 ft you are less likely to have problems but it still happens EVERY year.
If to the Abacos via Memory Rock I would leave from West Palm Beach.
This was on a slow 38ft Ketch a 4KTSB in the paralance.
