“Some boaters had assumed the magenta line, which was last updated in 1935, was a precise route through safe waters,” said BoatUS Government Affairs Senior Program Coordinator David Kennedy. “However, over time the forces of nature made the line inaccurate as shoals shifted and underwater topography changed, leading some boats into shallows, over dangerous obstructions, or even into land. We thank NOAA for a change of course in keeping the magenta line, listening to boaters and coming up with a creative public-private partnership that recognizes the value of this important guide to navigation.”
The magenta line appears in charts covering all Intracoastal waters, and is essentially two distinct routes along the eastern US and Gulf Coasts totaling about 3,000 miles in length. Said Captain Shep Smith, chief of NOAA’s Coast Survey’s Marine Chart Division, “Today’s decision to reinstate the magenta line is not a quick fix. It will take at least three years to fix problems that were 70 years in the making.”
