To sail the Exumas, on the other hand, you’ve got to show some determination just to get there. First you have the Gulf Stream crossing, which is a minimum of 48 nautical miles. Then you sail at least 65 nautical miles to cross Great Bahama Bank, which can be unpleasant if the winds kick up. On the other side, there’s the open-water run down to Nassau, another 47 nautical miles, before hopping from cay to cay to get to George Town, on Great Exuma Island. Nassau to George Town alone is 155 nautical miles, greater than the distance from Palm Beach to Green Turtle Cay.
