NEW UPDATE: NAV ALERT: LNM: Shifting Wreck, Savannah River Entrance, near AICW Statute Mile 576
Below I have charted the former G3 location (faded) and the current G3 location.
I believe this will help lessen the chance for a collision with the submerged wreck in nearby waters.
Interestingly the G3 Calibogue Entrance Buoy relocation shows up on NOAA RNC’s but not yet on NOAA ENC’s, which is the opposite of what I would expect. Here they are side by side:
I will be reporting this to NOAA.
FYI, the charted position [Wk] of the submerged wreck has been updated on the NOAA Charts – both RNC and ENC. USCG agrees that G3 and R2 would bring mariners too close to the vicinity of the wreck and told me yesterday they plan to move them.
In the meantime, please alert your mariners transiting in these waters of the need to update their charts.
Attached is are screen grabs showing the current positions on RNC and ENC charts. I will post on the FB page as well.
Good morning Mr. Arisaka,
I just check NOAA chart #11512 and the updated wreck position is charted. If the wreckage isn’t on the current ENC it will be updated with the next LNM. Regarding the pair of ATON in the area (GS and R2), a Coast Guard ATON team conducted a survey yesterday and agrees that current position of the ATON could cause mariners to sail into a navigational hazard. The two ATON are scheduled to reposition soon to guide mariners around the area.
Thank you for your concern and assistance,

Dear Chief Sherrill,
Many thanks for your update that got published on Cruisers Net about this shifting wreck. These are my home waters as a recreational boater on Hilton Head Island.
I did see it in LNM Week 45 thru Week 53 on page 40:
but as of 2020 Week 1 I see no mention of it anymore.
The report indicated it had been marked, but my friend who departed these waters southbound on 1/29/20 reported seeing no marker in that area.
As it is no longer in the LNM and there seems to no longer be a marker on the submerged wreck, I was wondering if it had been cleared?
Thanks and Best Regards,
Thank you for the information. The submerged wreck as not been cleared. The owner of the wreckage has not maintained the physical marker on the water. However, the new position has been updated on the NOAA chart and notifications regarding the navigation hazard have been distributed to boaters in the area.
I was unaware that the wreck was removed from the LNM. I provided the LNM office with the new information and it should be back on the next LNM publication. Thank you for pointing that out.

MSIB 01-20 Shipwreck Navigation Hazard Between Tybee Island, GA and Hilton Head, SC Near Savannah River Entrance.
On December 19, 2019, a commercial fishing vessel travelling from Calibogue Sound, SC towards Tybee Island, GA, struck an underwater wreck and quickly sank. Fortunately, all crewmembers were rescued. The accident followed another incident that occurred on November 3, 2019 when a recreational yacht struck the same wreck resulting in damage to the hull and propellers. Following the November incident, NOAA conducted a survey of the area and determined the position of the wreck and marked it on the NOAA navigation charts. The U.S. Coast Guard belives this wreck is the same as a steel-hulled commercial fishing vessel that sank in 2017 and was previously charted in the same area at position Latitude 32˚ 03.176’ N; Longitude 080˚ 49.839’ W. The wreck appears to have shifted approximately 700 yards to the Northeast into deeper water sometimes transited by vessels and is now located at Latitude 32˚ 03.480’ N; Longitude 080˚ 49.560’ W. The NOAA survey determined the wreck is completely submerged and extends from up to four feet below the surface.
Although the current position is marked, vessel operators transiting the area are reminded to update to the latest NOAA navigation chart, exercise caution, proceed at safe speeds, and remain aware the vessel may shift positions in the future. Any accidental allisions with the wreck should be reported immediately to the Coast Guard on Channel 16 VHF-FM or Sector Charleston Command Center at (843) 740-7050.
