The entrance channel at North Bimini is shallower than charted on Chart BIM 3, p. 54 of Explorer Chartbook Near Bahamas, 5th edition. A January 3, 2011, survey by the Explorer Team found the controlling depth to be 1.7 meters (5 2/3 feet) in the area of 25° 42.70’ N by 79° 18.25’ W. There was a little deeper water east of the dashed track. The sandbar west of this position has encroached on the entrance channel. Two larger buoys (red and green) are easily seen from well offshore, plus one smaller green buoy closer in to shore. The large red buoy is almost directly on the Explorer waypoint, so caution should be taken in approaching the waypoint. Channel buoys here have been unreliable in the past and the sand here is fluid and continually shifts. (Explorer Chartbooks)
