We have plotted the reported position of the “sunken chain” detailed in the cherry picked “Local Notice to Mariners” below, and it lies some 1.6 nautical miles west, of the westernmost of the barge canal markings which eventually split into two marked passages farther to the east. All these complicated channels are found between the Crystal and Withlacoochee Rivers.
Cruisers plying the Big Bend region between the Crystal and Withlacoochee Rivers should avoid this hazard, and be on the lookout for the “danger sign” described below, which marks this obstruction.
The Salty Southeast Crusiers’ Net is establishing a Navigational Alert for these waters.
