would be to head
for Memory Rock passage and no worries about depths or lack of navigational aids. If you do use Indian Cay passage...go on a 1/2 tide rising but this is not always convenient for making Great Sale
Cay which is generally the next stop after West End. Keep your heading 20 degrees south of the rhumb line to West End and the stream will push you there.
Don't think about going if there is a northerly component to the wind
...but you probably know that already.
Having done the trip many times...the best way from Florida
is to leave at night for an 18 hour or less passage direct to Great Sale
Cay via Memory Rock. This puts you crossing the Bahama bank in 12ft. of water
in daylight...with no worries about check ins or no see ums or timing tides. It also give you another day to play in the Abacos.
You cancheck in at Spanish Cay or Green Turtle AFTER you leave Great Sale. Just fly your Q flag and there are no problems.
Of course it is a bit daunting to leave for your first stream crossing in the dark...but winds tend to be lighter...you can see the lights of the ship traffic and come daylight...you are in the Bahamas
with about a 2-3pm arrival in Great Sale.
