Don't you have a chart plotter? Or paper charts? If you can't figure this out yourself you shouldn't be out there. What are you going to do if your plans changes while on the water?
I don't have any experience with that end of the Bahamas. I have been to Bimini, Chub Cay, Spanish Wells and Eleuthera all on my 42 Egg Harbor. There is a lot of shallow water. We had to pickup a pilot in Spanish Wells to take us thru the "The Devils Backbone", a string of coral heads along the beach, to get around the Dutch Bar and into Eleuthera. I wouldn't be surprised if you had to deal with a similar situation getting around West End around to Man O War.
But to answer a small part of your question about 60 miles. My Active Captain app shows routes on the bank inside the reef passage.
