  • This area is subject to channel location changes.
  • The navigation marks have been moved to mark the existing channel.
  • Thus, the NOAA charts for this area may not correctly place the marks.
  • On some editions of electronic charts, the channel is actually located where the chart depicts land or shoals.
  • Trust the marks, not the chart.
  • At 1700 9 Nov 2014, SV Onward found Dmin => 9' in the marked channel at Td 0.1' = ; TS = (Low Tide)

Inlet Report: 28 Oct 2016
  • The current LNTM reported the navigation marks for the inlet had all been carried off station by Hurricane Matthew.
  • I contacted USCG Sector Jacksonville and talked to the person in charge of navigation aids. The current list of off-station marks did not include St. Augustine; but he did not have a specific report that they had been replaced.
  • I called SeaTow St. Augustine and learned that some of the marks were in place.
  • I called TowBoat US St. Augustine and learned that the sea buoy and most of the red marks had been replaced.
  • I had left detailed waypoints for the inlet channel last year when I found it a challenge.
  • I was able to watch a fishing trawler make an exit on AIS and then watch the AIS of Cats Meow, a 72' cat and a large sports fisherman make the entrance and they followed the route
  • I followed the route and saw a min of 20' at 1445-1515; local low tide was at 1457.

Inlet Report: 27 Oct 2017
SV Onward observed other vessels on AIS and then used the above waypoints to negotiate the inlet. A minimum depth of 19.5' was seen just inside the sea buoy. The 2017 hurricane season did not seem to have affected the inlet.
