The islands of the Abacos ae strung along the north side of the Bahama bank...Shallow water
between the small isands to the north and Grand Bahama island to the south. Deep water
on the "ocean" side of the small islands.
There is not much diving on the banks but good diving on the edge on the north,seaward side, of the small islands.
There ae several places were you can anchor
on the bankside and walk across to dive on the ocean side. Access is at Marsh Harbor, Guana cay, and several others whose names I can't remember now.
With a good ,powerful, RIB inflatable
one can run to good dive spots from the anchorages
but they are not accessable with a lesser dinghy
When your used to 4-5 foot visability it is all prety amazing even if you dive off the boat and just see some turtle grass.
