STM:
65.0
Nav. Marker / Location: Albemarle Sound N entrance
Vessel Reporting: Onward
Date: June 2010
Report: While northbound in June 2010 Onward found the W side of the channel shoaling. Suggestion: stay to E side. In Nov 2010 Onward saw a minimum of 10.6' on this side.

STM: 81
Nav. Marker / Location: Entrance to Alligator River at Long Point Shoal
Vessel Reporting: Onward
Date: Oct 2009; May 2010; Oct 2010
Report: Electronic and NOAA charts continue to show a jog in the channel S of long shoal point. Following this information has consistently led sailboats to ground on the shoal. Onward followed advice from the local Towboat US operator and other boats who had safely traversed the area. Suggestion: Follow the markers in a straight line for a safe passage and not the "magenta line" on charts.

STM: 84.2
Single-Pivot Swing Bridge; Alligator River
Note: Perhaps the best bridge on the ICW in terms of boater-friendly / cooperative bridge tenders. Planning is underway (Oct 2016) to replace the bridge with a fixed bridge.
