We came in yesterday (1/29) mid afternoon, mid tide. The shallowest we saw was about 8', but mostly 10'. I'm not sure if we took the "old" or "new" channel. There are red and green buoys about 700 yrds off the beach. From a distance (heading E) line up with the south end of the red roof condos. There will be a highly visible ship wreck a bit farther south. Once through the first red and green, there is another much smaller green a bit south, about a couple hundred yards. Once past the second green keep heading E towards the beach, as there is a long sand bar that extends from the southern tip of N. Bimini. Don't turn N, toward the entrance to N. Bimini until you are about a couple hundred yards off the beach (visually confirm you are in the "good bluey water"). From here, there is a nice straight shot of good looking water. I was standing just below the lower spreaders, and it was very easy to spot the good water, and call directions to the helm
. Good luck, and as others have recommended, I wouldn't attempt this entrance in rough conditions.
