  • Shoaling Reported in Cedar Keys Channel, Big Bend Region, June 11, 2015


    Cedar Keys is one of a limited number of ports of call along Western Florida’s waterwayless Big Bend region, the Western Florida coastline between Anclote Key and Dog Island. The reported shoaling is in the main entrance channel to the east of Seahorse Key.

    FLORIDA – CRYSTAL RIVER TO HORSESHOE POINT – CEDAR KEYS MAIN CHANNEL: Hazard to Navigation
    The U.S. Coast Guard received a report of shoaling between Cedar Keys Main Channel Daybeacon 19 (LLNR 29805 [29°6.7123N / 083°2.7068W, 29.111871 / -83.045114]) 29-06-42.737N/083-02-42.411W (29°6.7123N / 083°2.7068W, 29.111871 / -83.045114) and Cedar Keys Main Channel Light 21 (LLNR 2981) 29-06-50.837N/083-02-25.131W (29°6.8473N / 083°2.4188W, 29.114121 / -83.040314) with depths as low as 3 ft at low tide. Mariners are advised to exercise caution while transiting the area.

  • Shoaling Reported South of Anclote Key, near West Florida ICW Statute Mile 150, May 9, 2014


    From Skipper Bakos’ report and with the several shoalings reported on the chart, it would seem prudent to avoid the southern tip of Anclote Key when entering or exiting the ICW between Anclote Key and Three Rooker Bar. If you have navigated this channel recently, let us hear from you.
    See also /?p=145021 for update on shoaling.

    There is also shoaling due south of Anclote Key charted as 8 to 9 feet depth. I ran hard on the shoal last night for 6 hours. It is about halfway between marker #5 on the south side of Anclote Key and the partially submerged wreck shown on the chart. There is less than 5′ at low tide there. Further south, closer to the wreck there was good depth.
    Bob Bakos

    I have seen several boats aground at the southern tip of Anclote Key over the last couple of years. The odd thing is that I haven’t run aground there yet as I seem to have a natural affinity for sand bars. On a good day, the shoaling is easy to see by the color; watch carefully for signs of breakers. Capt Bakos’ advice is good, always give Anclote a wide berth and watch your depth carefully.

  • Shoaling Reported at Hurricane Pass, near GICW Statute Mile 142, 6/23, 2016

  • Shoaling to Four Feet MLW in Clearwater Pass, near GICW Statute Mile 135, 12/5/2014


    This shoaling in the popular Clearwater Channel is at the southern end of the curving channel north of the fixed bridge .

    Our thanks to Skipper Fuller for catching our error. The symbol has been corrected.

    The alert is in the wrong position. The actual problem area is inside the bridge, at the southern end of the curving channel that heads toward the Clearwater Marina. That channel has long been a trouble spot, and it was dredged not too long ago. It has filled in very fast.
    There is no problem in the area shown by your alert symbol [now corrected].
    Gene Fuller

    Hi Larry,
    We passed through Clearwater a couple of weeks ago. I was shocked when we saw 5.5 feet in the trouble area, at HIGH tide. (We need 5.3 feet.) A year ago the readings were more like 10 feet.
    Regards,
    Gene Fuller

  • NAV ALERT: Rock Obstruction, Seaplane Basin, Tampa Bay, 2/1/2018


    The protected harbor known as Seaplane Basin lies just south of the city of Tampa, on the northern part of Hillsborough Bay.

    FLORIDA – TAMPA BAY – HILLSBOROUGH CUT D CHANNEL – OFF DAVIS ISLAND: Rocks Hazard Davis Islands
    The U.S. Coast Guard received a report of uncharted rock obstruction creating a hazard to navigation south of the entrance to the Seaplane Basin at Davis Islands, Tampa, Florida.

  • Shoaling on Southern Foot of Sunshine Skyway Channel, at the Mouth of Tampa Bay (near St. M. 98), 5/16/2103

    Even many veteran Western Florida cruisers have never known that the “official” path of the Western Florida ICW, across the mouth of Tampa Bay, cuts east-northeast under the huge Sunshine Skyway Bridge, and then takes a LONG curl back around to the north and west before passing under the Skyway’s northernmost section (known as the Misner Brige), and eventually rejoins the “official” Waterway just west of the Misner span. We don’t know of any cruiser who actually follows this route consistently.
    The vast majority of captains continue north from the Waterway’s buoy #1A, through what the NOAA charts call the “Sunshine Skyway Channel,” rejoining the Western Florida ICW at marker #15. As alluded to above, many mariners think this is all part of the “official” Western Florida Waterway.
    Not so, and that means that the Sunshine Skyway channel is not as carefully maintained as the Federally sponsored Western Florida ICW. And so, the shoaling reported below by Captain Davis is actually a long standing problem between Sunshine Skyway Channel markers #3 and #2. If memory serves, which sometimes it does not, while performing research here in 1992, for the first edition of “Cruising Guide to Western Florida,” we found less that ideal depths between #3 and #2.
    So, if your vessel draws more than 4 1/2 feet, try to time your passage through the southern foot of the Sunshine Skyway Channel for mid to high tide. And, note Captain Davis’ advice to favor the eastern side of the passage.
    In any case, proceed with caution. Once #3 and #2 are in your wake, the Sunshine Skyway channel soon deepens all the way north to the juncture with the official Waterway.

    Cruising News:
    Shoaling at marker 3 in the Yacht Channel [Sunshine Skyway Channel] just North of the Main Span of Sunshine Skyway Bridge in St Pete. Shoaling extends midway through channel, stay towards the Eastern (red) side. Hit bottom with 4.5 foot draft at mid tide.
    Cambren Davis

    There was a temporary red [marker] more to the east of the shoal spot a month ago. We favored the west and bumped with 4’5 draft at mid tide too. Next trip I’ll favor the east temporary red marker as suggested.
    Roy Cucchiara

    October 13, 2013
    We came this way five days ago and the shoaling at this point is worse than I have ever seen it. The middle of the channel looked like a sandbar and could not have had more than three feet of water over it. We draw 4 and 1/2 feet and came to a stop. There was a darker strip of deeper water to the east well outside the channel. We picked our way through by sight and feel and made it past the danger area. It was about mid tide on a strong ebbing tide so it was no place to run around. Caution is strongly advised.

A Safety broadcast to Mariners will be released notifying the public of the intended start date of this work.

  • Shoaling Reported In New Pass, between Longboat and Lido Keys, Sarasota, FL, near GICW Statute Mile 75


    New Pass is the northernmost of Sarasota’s two inlets and this channel separates Longboat Key from Lido Key. It is spanned by a bascule bridge with a closed vertical clearance of 23ft.
    Because of perennial shoaling, WE SPECIFICALLY DO NOT RECOMMEND THAT ANY MARINER MAKE USE OF NEW PASS! This channel shoals faster than it can be dredged. You would be far better served to make use of Longboat Pass to the north, or better yet, Venice Pass to the south.

  • Shoaling Reported south of Gordan Pass, Naples to Marco Island Channel, 1/17/2016


    Carey Moluchi reports observing shoaling in the inner channel which lies east of Keewaydin Island south of Naples.

    We have a 4 ft draft sailboat and took the inside passage from Marco to Naples Jan 15th 2016. We found a shallow area right in between the markers at #67 which is a few markers before the channel joins the main channel from Gordon Pass to Naples. We were on mid tide and our depth finder showed 4.2. So caution would be required at this location. We found the rest of the channel fine and it was well marked.
