Shawn, in addition the the great suggestions above, I'll add my following observations:
Bahama weather systems are often similar to SE Florida, but later. The further east you go, the longer it will take to hit you. (Maybe 1/2 day in the Bimini-Berry islands and 1 day or so in the Exumas)
Traveling on the banks, tends to knock the waves way down compared to deeper water
, but you'll likely encounter much larger seas crossing from the Berry Islands to Nassau. When I did this in my pocket cruiser
, the seas were 9 feet and I couldn't make Nassau on one tack so I tucked into the big bay on the west end of New Providence. If the weather isn't right and you don't have a compelling reason to go to Nassau, I recommend being open to heading from the Berry Islands up to the Abacos without stopping in Nassau. Flexibility often leads to more pleasant sailing conditions.
Have a great trip!
