  • Georgia Navigation Alerts


    Please note that “Navigation Alerts” listed in this section are are arranged in a rough north to south geographic format.
    “Alerts” are messages from your fellow cruisers which pertain to navigational problems or changes along the waters of the Georgia coastline. These “Alerts” are real concerns for Georgia mariners, and might range in subject matter from new shoaling to a missing aid to navigation.
    “Alerts” should be differentiated from our “AICW Problem Stretches” section. “AICW Problem Stretches” are sections of the Atlantic Intracoastal Waterway that seem to have perennial problems. Even after dredging, shoaling tends to reappear within a relatively short period of time.
    If you have arrived here, seeking information about AICW long-term concerns, be sure to also check out our “GA AICW Problems” section by going to the red, vertical menu on the right side of all Net pages (except Chart View pages). Click on “Georgia” and a drop down menu will appear. Now, click on “GA AICW Problems.” A page will open listing all the problem stretches along the Georgia portion of the Waterway.

  • Shoaling Reported in Sapelo River, west of AICW Statute Mile 636, 7/6/2016

    This area of shoaling is developing from the west and north side of the channel. This western portion of the Sapelo River departs the Waterway near Mile 636.

    Shoaling reported between Sapelo River DBN 6 (LLNR 5895) and Sapelo River DBN 10 (LLNR 5905). Depths are reported from 0-6 ft at Mean Low water. Aids to navigation are currently in 0 feet of water. Shoaling protrudes into the channel approximately 20 yards. Channel was found closest to the southern bank with a depth of 6-10 feet at Mean Low water. Chart 11510 LNM 27/16

  • Concrete Debris Along the Path of the AICW in Altamaha River (Statute Mile 657), 8/17/11

    The Waterway intersects the Altamaha River at mile 656 and runs in the Altamaha until entering Buttermilk Sound at mile 660. ALL cruisers traversing this section of the AICW need to be on maximum alert for the obstruction reported below! The Cruisers’ Net is declaring a Navigational Alert for these waters and a report has been filed with the USCG!

    Cruising News:
    On August 2, 2011 while traveling North there was a large piece of concrete with rebar partially exposed about mid tide on the Altamaha River between daymarks 204 and 206.
    Susan aboard s/v September Song

    Is this new or has it been there? Is it in the channel; if so red/center/green side? Or, out-of-channel? If so, which side? Has the Coast Guard been notified? This is good info, but what’s also needed is a better description of the location in case we’re there when the tide is in. (Not that that every happens to me, tho!)
    Thanks, Jim Healey

    It looked like it may have been a concrete pier, it was near the middle of the channel but closer to the red. No the coast guard was not notified.
    Susan aboard s/v September

    Thanks very much for following up, and for the CG notification. That must be fairly new, but it sounds like a really bad hazard for the unaware! We’ve been through there many times over the years, and I’ve never seen anything in that area before. But, the area is shoal, shallow, and does not lend itself to error; looks like, favor green” is the new rule.
    Actually, if the weather is right, we’ve taken to overnighting at the great Duplin River anchorage, then we go out at Doboy Sound and back in at SSI, or the St. Mary’s or St. John’s, to miss that whole Little Mud/Altamaha stretch. Too bad; we really love the salt marshes and the rural character of the area, but GA just does such a lousy job of keeping the waterway navigable! Maybe a hazard like this will get cleared before the fall migration.
    Thanks, again.

    As noted by Captains Jim and Peg above, SSECN Eastern Seaboard Editor, Captain Larry Dorminy, notified the USCG about the obstruction in Altamaha Sound/AICW. They replied:

    Thank you for contacting the Navigation Center.
    Your report concerning a hazard to navigation in the Altamaha River is currently being investigated by a USCG Aids to Navigation team. Please refer to the District 7 Local Notice to Mariners for any information regarding their findings. If deemed necessary, a Broadcast Notice to Mariners will also be issued. We thank you for your report.
    We hope this addresses your inquiry. In our continuing efforts to provide high quality services to our customers, please let us know if you found the provided answer helpful.

    The Coast Guard received a report of a large piece of concrete with rebar partially exposed about mid tide on the Altamaha River between Altamaha Sound Daybeacons 204 and 206. Mariners are advised to avoid this area. Chart 11508

    Just passed thru this area today with our 7ft draft Catalina 42. Tide was at about about +6ft. Ran directly down the center and did not hit anything or see anything. Found about 7ft MLW.
    It would have been good if September Song had indicated where they saw this obstruction. In the channel? To the side of the channel? Where was it?
    We have worred about this for many miles down the ICW but having faith with the heavy volumn of boats going thru hear we would have heard something by now.

    I passed through here 2 days ago [March 23, 2014]. Between daymarker 208-206 there is an obstruction marked, on the west side of the channel. I was 15 minutes before low tide (+0.4). I did not see the obstruction that was marked there was significant chop due to high winds. i did not see anything between 206-204 except for a significant amount of mud bank. The depth in the channel was 7-13 ft.

  • Sunken Vessel Debris, St Simons Sound, AICW Statute Mile 673, 11/17/2016

    This sunken vessel is between St. Simons Island and Jekyll Island just west of the Waterway’s path through St. Simons Sound as the Waterway rounds Marker #20 near the mouth of St. Simons Inlet.

    On November 5, 2016 the commercial F/V PREDATOR sank and broke apart in position 31°7′ 34.6343N, 81°25′ 16.2977’W, in vicinity of Jekyll Island in Brunswick, Georgia. Portions of the vessel still remain in the area and may break apart, float to the surface, or shift on the sea floor. Mariners transiting the area are urged to exercise extreme caution and if debris is sighted notify Marine Safety Unit Savannah at 912-652-4353 or your nearest Coast Guard unit. Chart 11489 LNM 46/16

  • CAUTION: Groundings at Marker #19 in Jekyll Creek, AICW Problem Stretch, Statute Mile 683, 10/15/2014

    We are receiving regular reports of shallow water and groundings in Jekyll Creek, a perennial trouble spot. SSECN recommends extra care and rmid to high tide only for this passage. See /?p=144835. Markers 19 and 20A are on the north side of the Hwy 520 fixed bridge. Ours thanks to Skipper Reeves who keeps us posted on all things Jekyll!

    October 15, 2014
    Sonny Reeves reports that another cruiser has run aground today at Marker #19.

    Hi Larry, I have an update on the infamous Green 19 of Jekyll Creek. [See link above for photos.] We went to the markers and slowly went back and forth. Sadly we found 4 ft at low tide where last year was 6 ft at low tide. The channel is very narrow. Tow Boat US advises to stay 40 ft from marker. Sailboat in picture was about 80-90 ft off the marker and turned wide running aground. This was at 2.5 hours until low tide. Here is a suggestion going South stay centered on Red 16 and Green 17 then as you turn to South West line up 40 ft off of Green 19, put Green 19 to port going South. Call the Marina or Tow Boat US for local knowledge. Wait for rising tide that may run 7-9 ft in this part of the ICW near MM 685. Hope this helps.
    Sonny Reeves

    And this report from Skipper Poovey:

    Hey, Larry.
    Came through here this morning at 10:15 AM ( 1 Hr., 45 Min. past High tide) from the North. Stayed within 25 ft. to the west of marker G-19 and read 5.8 feet on both sounders.

  • IMPORTANT – More on Marker/Charting Confusion and Increased Shoaling on AICW’s Passage Through Georgia’s St. Andrew Sound (St. M. 690), 8/10/12

    OK, ALL AICW cruisers bound through southern Georgia within the next six months (at least), LISTEN UP! It appears we have a serious problem on the AICW’s passage through often ROUGH St. Andrew Sound, south of Jekyll Creek/Island. The data detailed below was sent to the Cruisers’ Net by way of fellow cruising guide author, Captain John Kettlewell.
    Captain John, a good and long-time friend of yours truly, and I have been in close touch about this St. Andrew Sound situation, and compared notes. Unfortunately, neither of us has had occasion to research this portion of the Waterway for a good two years, so WE COULD REALLY USE SOME LATE BREAKING INPUT FROM THE CRUISING COMMUNITY CONCERNING THIS POTENTIALLY DANGEROUS SITUATION! If you have cruised the St. Andrew Sound section of the AICW within the last 4 months, PLEASE e-mail me directly at, or click the “Comment on This Posting/Marina/Anchorage/Bridge” link below!
    With that being said, it appears to both John and myself, that the charted shoal north and northeast of marker #32, may well have built out almost to the northern edge of this aid to navigation. Thus, if any vessel attempts to pass #32 to its northern or eastern sides, that sad sound of keel meeting sand (or mud), will be the result.
    As Captain John notes below, the marker numbering scheme, and the placement of the infamous (and ofter incorrect) magenta line in these waters is truly bizarre. John suggests, with good reason, that #32 might now be an inlet marker, and should be passed to its safe, southern side when cruising east to west through St. Andrew Sound Inlet. I agree with John that this seem plausible, BUT, conversely, the numbering suggests #32 is in fact an AICW marker.
    Our collective best advice at this point, is to be SURE to pass #32 to its western and southwestern flanks, without straying too far from this aid to navigation. Under no circumstances should you attempt to pass #32 to its northerly side. Ignore strangely placed marker #31A. From #32, southbound AICW craft should point to eventually come abeam of marker #33 well to its western side. Note that it’s a long gap between #32 and #33!
    OK, AGAIN, we need to more input on this situation. PLEASE let us hear from you! The SSECN is declaring a Navigational Alert for these waters!

    Update as of 12/2013

    We had a wild ride southbound through the Sound on November 30, 2013 in our 26 foot Glacier Bay cat. Conditions were a lot rougher than I anticipated, and visibility got bad due to spray and the occasional breaking wave over the bow. We shaved marker 32 close on the western side, and had 10 foot depths that dropped very quickly to 35-40 feet almost immediately after we passed the marker. There were solid breaking waves on the big shoal to the east of the marker at the time, so I suspect it was close on to low tide.

    I came through traveling north on 10/13/2013 at mid-tide following the Magenta Line as usual. No problem. Saw 60′ between Stm 690 and R32 dropping to 16′ just past R32.

    Well, we know that r32 is off station. It is actually north east of the charted position and located on the edge of the shoal that goes bare at mllw; so any vessel with 5’ or more draft can be in trouble. It’s a money maker for Sea Tow.
    The troubling issue is why the course line is drawn incorrectly to the west of that buoy but actually provides a guide thru safe water? Did NOAA know it’s off station and just drew the line incorrectly to give us a hint? Interestingly, if you look at a chart that’s about 10 years old ; you will see the course line is drawn on the correct side!. When a person is piloting the sound for the first time; what should they believe; the buoy or the course line? That could be an interesting debate between husband and wife and/or Captain and owner! I didn’t see any notices to mariners about the buoys location.

    Here is what I am guessing, but do not know without some further research. The R32 may now be positioned as a red-on-right marker for those returning from the ocean via the inlet, therefore they want you to leave it to starboard when inbound from the ocean, but in reality you need to leave it to port when headed south on the ICW. This would mean in addition to its red color it should have a fluorescent yellow square on it indicating that it is considered a port-side beacon for the ICW (when southbound). Though according to the most current Light List, those markings are not the case so I may be wrong in this guess. Or, you could be right in that the buoy is simply off station. I will try to find out more and get back to you.
    John Kettlewell

    Take a look at the following messages with regard to R32 in St. Andrew’s Sound. For some reason the magenta line on the chart is on the wrong side of the buoy and has been for years, but this fellow says that now the R32 is on the edge of the shoal to the NE and if for some reason you do leave it to starboard when southbound it will put you aground. Do you have any information on the area you can share?
    John Kettlewell

    And, as usual, the cruising community is responding by sharing useful information! There just aren’t any better folk than cruisers!

    Between 2009 and 2011, my wife and I made 4 transits of the sound on our sailboat, which draws 5 ft.. Our last was north bound to NJ in late March 2011. We were traveling with another boat and followed him through. We both treated Red “32” as an AICW bouy and passed close to port, because of the narrow channel. I always monitor closelly my nav instruments and and don’t rememmber the exact depth, but I am sure it was double digits. Everything seemed routine and no different than previous transits. Red ” 32 ” appeared to be in its usual position. As far as the magenta line is concerned, it is not unusual to see it out of place.
    I would add that the sound and behind Jeckel Island are some of the more challenging parts of the waterway and have my respect and full concentration. I remember the crossing well, because the wind was from the SE and blowing around 18 to 20kn kicking up quite a sea. I felt like I was in a washing machine.

    All Sailors
    We passed thru this area July 23 2012 bound for our home port of St Augustine. Our observations were :
    First , R32 was east and somewhat north of our chartplotter position
    Second , It was half flood tide and depth sounder showed 6 feet on that side ( we left it to starboard per ICW southbound )
    Third , G31A was nowhere in sight
    We have had several nasty storms along this coast in June ( Berrell ) and in July ( Debbie ) and others without names.
    Notices have been posted to be watchful for missing marks, etc.
    Our sailboat,Santana, draws 3 feet 8 inches which is becoming desireable around here Safe sailing to all.
    Captains Matt and Margaret
    PS On the same trip, we encountered 2 , yes 2, funnel clouds in the St Simons/ Brunswick inlet on July 19 and turned around and went back out to sea. They were not forecast!

    We passed St.Andrew Sound red 32 northbound in April this year and kept it close to port as we made the turn. We draw 5 feet and depths were not a problem. The breakers to the northeast were very obvious, very visible. The mark may have shifted since then as there have been two TS’s that have blown through this area in late spring/early summer.
    Steve and Sheila Kamp
    S/V Carolina

    We transited this area last spring and twice last year. We always pass on the southwest side of R32 approximately where the magenta line shows on your chart. We have been skeptical of the channel between G31 and R32 for a years.
    Walter and Ellen Solomons
    M/V Rachel

    In January of this year (2012) we were headed south and kept R32 on the Starboard side, on our return trip in April we kept it to port. We draw 5 feet and had no problem. We did stay close to the mark both times. We do not have a chart plotter, and had a 10 + year old chartbook so gave no thought of passing R32 on the “wrong side.” If I remember correctly, it does have an ICW yellow triangle on it.
    John and Georgie Jackson

    Passed through here the 6th of May and did pass to the West side of “32″ as I always do having a draft of 3′. I do this as it allows for a more gradual turn and I never see less than 10′ and this is not overly close to the mark. Has anyone reached out to the local towing services or the USCG for their input???
    Donovan (EOS, TC-44)

    Jim Reed's tracks

    We passed this area on 4/16 going north and got very confused and concerned about the water depth. About 6 ft. I believe we took R32 port side on the way back whereas we might have cut it going south. I have my fairly detailed track files for the trips if they are desirable but they do not show the depths recorded.
    Jim Reed

    We transit this route several times a year. Last transit was June of this year heading north to Brunswick. We have a full keel 6ft draft sailing vessel and usually time our passage close to high tide due to transiting Jekyll Creek. We always pass R32 on the east side of the buoy as the CG stated (the Magenta Line is incorrect in the turn). It is a tight turn and particular attention should be paid to the alignment of G 31A and G 31 as you round R 32 keeping it to port (heading north). It is a little unnerving due to the quick depth change (deep to shallow) but there was at least 15 ft of water at high tide in June. Pretty much the same for the past 3 years. Hope this helps.
    Capt. Jesse Price s/v Wind Dust

    December 18, 2013. Note the Local Advice!
    Passed 32 today. Steered a course from 31 to 32 heading south and passed about 100 ft on the wrong side of 32. Minimum depth at 32 was 15.8 ft. With tide at 6.1 ft over mlw. Locals at marina also advised passing on the wrong side.

  • Shoaling Reported in St. Marys River, East of St. Marys, GA, May 13, 2014

    For cruisers wanting to make a side trip to visit historic St. Marys, GA, the  St. Marys River departs the Waterway at statute mile 712. This reported shoaling is in the dogleg just a mile east of St. Marys docks. The charted shoal between markers #6 and #8 would suggest that favoring the east side of the channel would be best. For more on the St. Marys River, go to /?p=123715

    There is excessive shoaling protruding approximately 15ft into the channel between St Marys DBN 6 (LLNR 6805) DBN 8 (LLNR 6810). The Coast Guard has re-established St Marys TEMP Buoy 6A in position 30-42-52-379N 081-32-00.613W. Mariners are advised to exercise extreme caution while transiting the area. Chart 11503 LNM 19/14
