Bimini if fine, but the channel, at least last year about this time, is only partially marked. You should get some local knowledge before attempting entry. As of last January, the channel was deep enough for us (6+). Here are some waypoints/info that we provided to another boat last January:
Here you go, with all of the usual caveats. We came out with a tide about 2 feet over low tide. The lowest point we saw was about 8.8 feet. I think it would have been deeper if we waited a bit longer before starting to make our turn to the buoys.
They should like up midway between the two outer makers from the west, then these points should work:
Let me know if these work for them. The visual instructions are to line up, and then head
directly for the channel going to the small basin South Bimini. Then, when perhaps 200-250 feet from the west shore of South Bimini, start making s slow turn to the left, so that you end up 150 feet from the shoreline. Then keep that distance, and watch the makers put in by locals when closer in. Worked for us in reverse.
I would want to verify that the channel has not shifted since then, especially after Sandy's visit.
