MK....If you haven't done the Indian Cay route before you will have your heart in your mouth for the first mile or so with your draft. DEFINITELY wait for mid tide rising. The waypoints for the route found in the Explorer chartbook for near bahamas or the Dodge Guide to Abaco are the ones to use. Do not rely on the marker posts shown on the charts as some of these are always missing in action.
The Memory rock route will take you a little longer to get to from OBB ut will give you 9 ft. at least all the way.
