NOAA issues new edition of Miami nautical chart

Cruise ship traffic congestion around the Port of Miami should be eased somewhat with NOAA’s release of the 44th edition of Miami Harbor nautical chart 11468. The new edition will help alleviate congestion at the Port of Miami – the worlds’ busiest cruise port – by giving ship pilots a better display of the approach into the port.

The previous Chart 11468 showed only half of the precautionary area where vessels gather before coming into port.

“At the request of pilots and port officials, NOAA reworked the old chart and covered more area,” said Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “The cruise industry needed better chart coverage of the entire precautionary area to remove risks to navigation.”

The new edition also includes updated depth measurements gathered in February by a NOAA vessel that conducted a fast-paced hydrographic survey of 64 square nautical miles of critical area. Their survey also found four underwater obstructions and a wreck in the shipping channels, which were added to the new edition.

Chart 11468 – Miami Harbor is now available as a paper print-on-demand nautical chart, as a free PDF digital download, and as a free raster navigational chart for electronic display systems. It is also the last chart that the federal government will print using traditional lithographic printers. The corresponding electronic navigational chart US5FL22 will be available for download in early May. As announced last year, the federal government will no longer print traditional lithographic nautical charts, but will continue to provide other forms of nautical charts, including print on demand paper charts and versions for electronic charting systems.

NOAA’s Office of Coast Survey is the nation’s nautical chartmaker. Originally formed by President Thomas Jefferson in 1807, Coast Survey updates charts, surveys the coastal seafloor, responds to maritime emergencies, and searches for underwater obstructions that pose a danger to navigation.
