Kevin...Why go to Bimini at all? 6.5 draft is tough there anyway.
You can leave out of Ft. Lauderdale and go either the conventional WestEnd/Memory Rock way to Abacos or head to the new Providence channel and enter at little harbor.
The easiest way to Abacos is out of West Palm Beach to Memory Rock passge and on to Great Sale Cay for your first stop. Then next day to Green Turtle Cay for customs check in and you're there with no hassels. Since you are coming down the ICW...West Palm (lake worth) is the BEST place to wait for weather and to cross from so I don't understand the Bimini Plan at all unless you are heading to the Exumas and not Marsh harbor.
