    • Eastern Florida Navigation Alerts


      Please note that “Alerts” listed in this section 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 Eastern Florida coastline. These “Alerts” are real concerns for Eastern Florida 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 “EF AICW Problems” section by going to the red, vertical menu on the right side of all Net pages (except Chart View pages). Click on “Eastern Florida” and a drop down menu will appear. Now, click on “EF AICW Problems.” A page will open listing all the problem stretches along the Eastern Florida portion of the Waterway.

    • Update on Groundings South of Fernandina Beach, AICW Statute Mile 719.5

      Reports of shoaling south of Fernandina Beach have been coming in for several years and prompted a USCG Hazard Warning in May of 2014 (/?p=140702).This shoaling lies c. two miles south of Fernandina Beach harbor just north of the Waterway’s turn into Kingsley Creek. Our thanks to Joe Plunkett for sending this 9/2016 report.
      Now Joe sends us a welcome new report on changes in the Nav Aids around the shoaling.

      Problem area 300 meters north of old temporary red #2 in Amelia River south of Fernandina Beach has been addressed. Passed by this area on 3/3/17 and noted that the USCG has installed a new marker [Red 2] at the sandbar I grounded on 9/4/16. [See LNM below for [position] USCG requested comments in December replacing temporary red marker#2 with a permanent marker. I used the opportunity to comment and am pleased to see the USCG response. Semper Paratus.
      Joe Plunkett

      And Joe adds in response to Bob’s question:

      I copied the following from the the District 7 Local Notice to Mariners, Week 10-17:
      The following changes have been approved to the Aids to Navigation System in St Johns River, Fernandina Beach:
      Fernandina Beach TRUB 2 will be permanently discontinued
      Fernandina Beach Daybeacon 2 (LLNR 37988) will be established in position 30-38-54.689N/081-29-03.486W (30°38.9115N / 081°29.0581W, 30.648525 / -81.484302)

      And this:

      When I passed through the Amelia River south of Fernandina last week I noticed a new red temporary marker had been placed at or near the location where I grounded last September. I did not take note of the number on the temporary channel marker. Back in September there were three channel markers identifying the channel: a green #1 at the northeast end, a green #3 and a temporary red #2 at the south/southwest end of this section of the Amelia River. There are now four channel markers: The original green #1 at the northeast end of the channel, a new red temporary marker near the location of my grounding, the original green #3 and a new permanent red marker replacing the old temporary marker at the south/southwest end of this section. I did not note the numbers on the new markers. I do not find these new markers on my charts. I use Navionics on my chart plotter and updated the Navionics chip the evening before departing Fernandina heading south. I expect the changes have been or will shortly be published in the Notices to Mariners.
      Joe Plunkett

      Encountered less than 3? at near high tide 300 meters north of Temporary Red #2. Time was Approximately 1330 Hours on 9/4/16. Pulled out port shaft attempting to get off. About ninety minutes later while awaiting tow, observed outboard run aground near same spot. With outboard trimmed up, operator was blowing substantial amounts of sand.
      You must favor the green side when approaching Green #3 from the north or departing Green #3 from the south. Came through this area northbound in late June and did not have any trouble.

        Can you indicate where the red 2 temporary mark and the new permanent mark is located? Is it near green 1 or green 3? Thanks.

        This should not be a problem area if people just pay attention to their charts – there is lots of water on the eastern side of this area – from G1 to G5. I went through at low tide about five weeks ago, and I draft 5 feet. That’s the third time in the past year I’ve passed through here btw.
        Basic arithmetic tells you that with a tidal range here of 7 feet, this boater was clearly out of the channel to find only three feet.

    • LNM: Shoaling at AICW St Johns River Crossing, Statute Mile 740, 2/23/2017

      This Waterway shoaling is building on the northeast side between Green Markers #5 and #7, just south of the Waterway crossing of the St. Johns River.

      The Captain of the Port Jacksonville advises all mariners transiting in vicinity of Pablo Creek and Mile Point on the Intracoastal Waterway, that a shoal is forming on the northeast side of Pablo Creek. The shoal extends from east of Pablo Creek temporary Lighted Buoy 5 (LLNR 38360 [30°22.6438N / 081°27.3008W, 30.377397 / -81.455013]) to southeast of Pablo Creek Temporary Buoy 7 (LLNR 38370 [30°22.5073N / 081°27.1674W, 30.375122 / -81.452790]) and encroaching to the south and west of Pablo Creek. Minimum depths of 7 ½ feet are recorded in this area. Mariners transiting this portion of Pablo Creek with draft concerns are advised to navigate with caution while passing through this area.

    • Stiff Currents at San Pablo/Atlantic Boulevard Bridge, AICW Statute Mile 744.5, plus new comments

      Click for Chartview

      San Pablo/Atlantic Boulevard Bridge crosses the Waterway at Statute Mile 744.5. Having seen the currents here for myself, I can tell you that Captain Ising isn’t kidding nor relaying inaccurate data. The water movement can be fierce!
      In recognition of that fact, we are establishing an SSECN Navigation Alert for these waters!

      We just passed through on 16 Sep 2012 at what was likely max ebb and barely made 1.0 kts SOG. Our boat under full power will do about 6.2 kts, so I estimate the current can get as high as 5+ kts. It was scary with boats ahead and astern wondering if we were going to make it.
      Duane Ising

      In all of Jacksonville that bridge has the strongest current first only to the Main Street bridge on the Saint Johns river In downtown Jacksonville. The travel under this bridge must scrutinized according to the tides as it is a truly powerful funneling of water through a narrow gap. Water flow can exceed 6 knots.
      Dave Bennett

      My boat is at Harbortown Marina right there at Atlantic Blvd and the ICW, and yea, I can’t go anywhere when she’s running strong. The current is just as dangerous two miles north where the ICW crosses the St.John’s River, stay well away from the jetty and watch your sideways set action.
      Keith Blankenship s/v Renasci

      We came through this bridge about the 13th of Nov. 2012 and it was horrible !! Outgoing tide and we had all we could do get through ‘“ my guess is that we were doing no more than 1 ‘“ 1.5 knts; plus the turbulence approaching and under the bridge was like a washing machine. This is an extremely dangerous situation and most expecially when you some idiot approching from the opposite direction with the current, can obviously see that you are having a major control problem and continues to enter the bridge.

        If you go to the website you can easily see that the Atlantic Avenue Bridge has the strongest daily currents on the entire US East Coast. Use caution and timing and enjoy the push, but wait out the adverse current if you cannot maintain over 7 kts…:D

    • Watch Out For Shoal East and Southeast of AICW Marker #49 (Statute Mile 772), 5/16/2014

      On the morning of 5/16/14, the Salty Southeast Cruisers’ Net received a telephone call from Francis aboard “Easy Rider.” She reported that they were northbound on the AICW, and had just observed a larger powercraft hard aground, AT HIGH TIDE, on the charted shoal east and southeast of marker #49. She went on to say that this was the very same spot where they had a grounding problem with their own vessel a year ago.
      While we cannot yet confirm this hypothesis, it seems likely that the charted shoal east and southeast of #49 has built out farther towards the AICW channel. Prudent skippers will pass #49 well to its western and southwestern side.
      If anyone has any additional information about this hazard, PLEASE use the “Comment” function below and share that information with our fellow cruisers! Our thanks to Skipper Michelle for confirming the advice to favor the west side of the channel.

      SeaTow mentioned this area as a problem to our group recently. I went up to check it out yesterday and it is very shallow E and NE of green marker 49. Your suggestion is spot on to stay on the west side of the channel.

      We passed 49 about 150 to the West in about 30 ft of water at just about the beginning of a rising tide without a problem on June 3 at 1140am

    • Incorrect Charted Height at Broadway Bridge, Daytona Beach, Statute Mile 830.5, 5/13/11

      Cruisers’ Net Bridge Directory has this bridge listed as 62ft and care needs to be taken at high tide as Almost Heaven relates below. The Broadway Bridge (E International Speedway Blvd) crosses the ICW at Statute Mile 830.5, south-southeast of unlighted daybeacons #33 and #34.

      This Bridge is 62′! on a high tide we would not clear this bridge.(63.5 + Antennas) The Markers on the bridge clearly showed 63′ with the tide down 1 foot. Please consider the tide range when passing under the Broadway Bridge. The chart is INCORRECT as it shows 65′.
      Almost Heaven

      This bridge needs a proper clearance board. ie: measurement. I crept under this spring with the board reading 63. My antenna usually hits at a 64 reading. Antenna did not hit.
      Skipper Paul Eckenroth

      Our mast height is also 63.5′ + antennas, we passed under this bridge @ 8pm Sunday May 13th, 2012. The Bridge clearance guage showed 62′ but as we had previously cleared this bridge in the fall we gave it a very slow go weaving between the nav light. As far as we could tell not even our antenna touched (unlinke many other bridges on the AICW) which means there is at least 66+’ in the middle of the span.

        The clearance boards indicate MINIMUM height. Run down the middle of the span and you add at least 1 1/2 feet. We confirmed this on October 11, 2013. After waiting seven hours to pass under using the range board, going under the center our ant. did not even touch.

    • Severe Shoaling and Groundings, South of Ponce Inlet, AICW Statute Mile 844, 7/3/2016

      Waterway marker #17 is on the north side of the east-west channel north of an elbow turn. Our thanks to Richard Holtz for this Alert. See /107845 for earlier reports of shoaling in this area.

      Area of Marker 17 New Smyrna Beach three vessels grounded today during low tide. There is water North and East of the marked channel. Recommend you call Sea Tow or Boat US before transiting area. This is at the ICW Western Cut South of Ponce Inlet and Rock House Creek.
      Richard Holtz

      There were three hard groundings today just North of R18A and RG C at the start of the ICW Western cut south of Rock House Creek.
