I certainly wish the USCG could have been a bit more specific about the location of the semi-sunken vessel described below. It looks like to us that the derelict sits somewhere north of the Pineallas Bayway “E” bridge, and not too far from the Western Florida ICW. All vessels northbound on the ICW, north of Tampa Bay, please take note!

FLORIDA-WEST COAST-PINELLAS BAYWAY: Hazard to Navigation.
The Coast Guard has received a report of a sunken 40 FT recreational vessel with an aluminum bimini top exposed 3-4 FT above the waterline S of Isla Del Sol near the Pinellas Bayway Bridge Echo. All mariners are advised to transit the area with caution!

This semi sunken vessel is located close to Isla del Sol and well out of the Intracoastal running along structure E. It basically sits in the basin that have some other derelict vessels and can only be entered with local knowledge, as there is a very shallow sandbank surrounding the area. On the map, this area with the sunken vessel does not even show depth.

This alert should be moved to the east as this semi sunken vessel is near the beach next to the Pinellas Bayway and no concern to cruisers except as a curiosity.

Wow, here’s a notice that sends a chill up my spine! We have charted the reported position of the exposed steel I-beam, and it lies right on the Everglades National Park boundary. Many cruisers follow this boundary because crab pots and fish traps are not allowed in park waters. I can just see someone cruising these waters at night, and meeting up with this scary piece of metal!
So if you are going to be cruising north or south past Cape Sable ANYTIME this year, be SURE to follow the “Navigation Alert” link below and make careful note of where this obstruction is located!!!!

FLORIDA-EVERGLADES NATIONAL PARK-FLORIDA BAY-EAST CAPE: Hazard to Navigation.
The Coast Guard received a report of a rusted steel I-beam exposed above the waterline 1 FT at high tide and 6-7 FT at low tide I NM west of
Middle Cape Sable in position 25-09.305N 081-09.671W. All mariners are advised to transit the area with caution. [Ref: SKW BNM 054-11] Chart 11433

These I-Beams are not limited to West Florida. I have seen them all along the Everglades NP boundary, marking the edge of the ICW on the upper Keys – unlighted and essentially invisible – just waiting for someone to run into them at night.”

Gordon Pass is the primary inlet for all cruising craft entering and leaving Naples and Naples Bay. This passage was shoaling badly until January of 2010 when it was dredged. Now, according to the Local Notice to Mariners item listed below, shallows are beginning to once again encroach on this important channel. The shoaling seems to be taking place near markers #1 and #2, which are the westernmost aids to navigation with number designations on the inlet channel.
All mariners traversing Gordon Inlet should proceed with extra caution!

FLORIDA-WEST COAST-LOSMANS RIVER TO WIGGINS PASS-GORDON PASS CHANNEL: Shoaling.
Shoaling has been reported in the vicinity of Gordon Pass Channel DBN 1 (LLNR 17453) and Gordon Pass Channel LT 2 (LLNR 17455) in approximate position 26-05.492N 081-48.388W. All mariners are advised to transit the area with caution. [Ref: STP BNM 271-11]

We have charted the reported sunken craft featured in the Local Notice to Mariners extract below. The derelict seems to lie hard by the southern flank of the official ICW channel, south of Point Pinellas, and between markers #6 and #7. Many north or southbound captains, who do not wish to enter Tampa Bay, bypass this portion of the Western Florida ICW, by following the so-called Sunshine Skyway Channel. In fact, many think this latter route is actually a leg of the ICW.
However, tons of cruisers on Tampa Bay make use of the ICW channel to exit Tampa Bay, cruise under the Misner Bridge and then cut north towards Clearwater on the Western Florida ICW. ALL cruisers plying this route will want to make note of the sunken vessel described below.
And, if you have more information about this derelict, or have seen it, PLEASE click the “Comment on This Posting/Marina/Anchorage/Bridge” link below, and share your information!

According to the message below, which is extracted from the Local Notice to Mariners, a sunken sailcraft with attached dinghy lies hard by the northern flank of the Caloosahatchee River – Okeechobee Waterway Channel, near marker #90, and just east of Cattle Dock Point and the entrance to Tarpon Point Marina. ALL MARINERS NAVIGATING THIS WESTERNMOST PORTION OF THE CALOOSAHATCHEE RIVER NEED TO TAKE NOTE OF THIS HAZARD TO NAVIGATION!

FLORIDA-OKEECHOBEE WATERWAY-FORT MYERS TO CHARLOTTE HARBOR AND WIGGINS PASS: Hazard to Navigation.

Well, clearly sometimes we can’t trust reporting on the Local Notice to Mariners. See below!

I can see that location from my home on the Caloosahatchee. as of 1030, Sunday 20 Feb. the reported vessel is not there.
