Several portions of the AICW show significant shoaling, specifically those areas near mile markers 237, 271, 280 and 321 in North Carolina. There have been and continue to be groundings in these areas.
Shoaling conditions increase the potential for vessel groundings, and any vessel grounding presents a significant risk of injury and vessel damage.
The captain of the port for Coast Guard Sector North Carolina suggests all mariners take the following precautions while transiting the AICW in these areas:
• Transit at the slowest safe speed and proceed with caution
• Conduct proper pre-voyage planning when intending to transit these areas
• Transit at high tide and in daylight hours
• Ensure vessel drafts are adequate to transit the AICW
• Do not attempt to overtake or meet other vessels in these areas
These areas are subject to continual and sometimes rapid environmental changes. Some aids to navigation on the AICW may not be charted and may be marking best water outside of the federal channel due to continually shifting shoals.
