Bob423 Long Tracks

4/14/2024 Update: The Savannah to Titusville track has been updated to follow the ATONs through Ft Matanzas. The previous track avoided the dredge pipes but they are now gone. 

I've also included a package of 18 side trips that start adjacent to the blue-dotted Bob423 ICW track and show the way to marinas and anchorages that I use. The side trip tracks are in red to avoid confusion with the blue Bob423 ICW Track. All GPX files have been tested to load properly and display with Aqua Map and Navionics. Garmin Active Captain will load the files but won't display the entire length sometimes, use Track Splitter to cut them into smaller segments for Garmin products.  

NOTE: I have not yet achieved infallibility (although it is one of my goals). The tracks are as good as I can make them but the ICW is always changing due to shoaling, dredging, barges pushing mud around (into channels), high winds pushing water out, and a number of other factors. As always, the captain takes full and sole responsibility for his vessel in using these files. Always use the latest file for a day's run. 

Before following Bob 423 tracks, please see link: Rules of the Road

To understand what goes into forming and updating a Bob423 track see: Basis for Bob423 Tracks

1 - Norfolk, VA to Southport, NC, adjusted for shoaling at Mason Inlet
B423 Norfolk to Southport 032824

2 - Southport, NC to Savannah, GA - The detour route option around the 3 to 4 MLLW shoaling at Isle of Palms has been added to the Southport to Savannah track. It appears as a red dotted line adjacent to the blue dotted line of the main track. It should be considered at low tide for more water.

3 - Savannah, GA to Titusville, FL update to follow the ATONs at Ft Matanzas. The previous version avoided the dredge pipes but they have been removed so we’re back to the ATON marked route. 
B423 Savannah to Titusville 041324

4 - Titusville, FL to Miami, FL, The ICW crossing at Jupiter Inlet las been dredged. The new track goes through the deepest section. 
B423 Titusville to Miami 012824

5 - All 18 side trips for safe passage into Homer Smith Marina in Beaufort, NC, Jekyll Island Anchorage, Bethune Anchorage in Daytona, FL, Cedar Creek Anchorage, NC, Pungo River Anchorage, NC, Ft Matanzas Anchorage in FL, and many others. All side trip tracks are in red and start near the blue dotted Bob423 ICW Track.

6 - Ft Lauderdale to Key West Tracks

Miami to Tavernier (Blue Waters Marina)
8.8 MLLW in Biscayne Channel
4.9 MLLW over bar on approach to Blue Waters Marina in Tavernier, use tide. Do not stray from track on approach to Tavernier, I did once and grounded (do not cut corner on approach). Much deeper once over bar.

Tavernier to Marathon
4.9 MLLW over bar at Tavernier exit, do not cut corner, follow track.
8.0 MLLW in channel at Marathon between G3 and G5.
T_1_26_20

Marathon to Key West
8.0 MLLW in channel at Marathon between G3 and G5.
T_1_27_20

Key West to Long Key anchorage
4.8 MLLW at Long Key anchorage. Anchor farther out for more water.
T_4_30_20

Long Key to Adams Key
(Caution, do not attempt unless you understand how shallow the water is on the approach and exit from Adams Key - attempt only at high tide when you will have 5 ft of water on the bay side)
4.8 MLLW at Long Key anchorage, anchor farther out for more water
4.6 MLLW over bar at entrance to Adams Key (between R2 and R4), use tide for more water.
11.5 MLLW at anchorage next to ranger station

Marine Stadium in Miami to Adams Key
(Caution, do not attempt unless you understand how shallow the water is on the approach and exit from Adams Key - attempt only at high tide when you will have 5 ft of water on the bay side)
4.4 MLLW over bar to Adams Key, just north of G5. Use Billys Pt tide station. I go in with a 1.3 tide so I saw 5.9 ft of water for my 4' 9" keel. Do not deviate from track! (it may look strange but it works). The reward is a 360 protected anchorage with shore access for a dog and a park for a walk.

Marine Stadium in Miami to Ft Lauderdale
7.4 MLLW on approach to Marine Stadium

Angelfish Creek in the Keys
Track from bay to ocean for 4.6 MLLW as of 4/14/2023 using the Ocean Reef Harbor tide station for reference. There is a 100 ft section between R2 and G3 that's less than 6.6 MLLW. It's deeper on both sides of the shallow area. '

Approach to Key Largo harbor (the one with "crash corner")
The track starts at R2 to just inside the entrance to the canal for 6.2 MLLW. Use the Key Largo South Sound tide station for tide reference. When approaching the 90-degree turn, announce yourself over VHF, "(name of boat) approaching crash corner inbound".

Approach to Loggerhead Marina in Vero Beach, FL for 6.0 MLLW with Wabasso Bridge showing 64 ft of clearance. The Wabasso Bridge height boards are a good indication of water levels. If the Wabasso Bridge shows 63 ft of clearance, then there's an additional foot of depth (7.0 MLLW). If the Wabasso Bridge shows 65 ft of clearance (which almost never happens), then there's only 5.0 MLLW on the approach.
