GPX Routes

(Updated 10/10/2018, Snows Cut)

The 2018 ICW Cruising Guide will give more details including depths on the routes but the GPX download links are included below for ease of updating if things change. 
Caution: the routes were ones I personally used in the spring of 2018 except where noted, however, things change on the ICW and the captain of his or her vessel takes full responsibility for the safety of the vessel and crew.    
The pages refer to the 2018 ICW  Cruising Guide

Page 186:  Sawpit Creek Shoaling by G49  MM731
Route from Hobe Sound to Ft Lauderdale with bridge info. Each lift bridge is named in the route list with its opening schedule for easy reference. When underway, each bridge will have an ETA or arrival time so you will know if you need to speed up or slow down. The ETA feature is only available with the Aqua Map app on iPad or Android.
Page 216:  Caesar's Creek passage from Biscayne Bay to the Caesar's Creek anchorage. MM1115. I’ve taken this route multiple times but it only has 5.1 depth at a max tide of 1.3 ft.

I used OpenCPN and AquaMap to form the routes. OpenCPN is an open source, free charting program with tons of capabilities, perhaps too much for some but it works very well. I also found that it's easy to form routes using AquaMap's routing tools on my iPad. On your desktop, laptop, or iPad, choose one of the options below:

GPX File use:
A GPX file is a universal format used to exchange routes, waypoints, and tracks between navigation apps and programs and is supported by all such programs. Examples for loading a GPX file into sample programs and apps are given below.

Easiest:  Use your iPad and download (no laptop needed)
- Use Safari to open GPX Routes (other browsers may not work)
- Tap on the GPX file link.
- A screen will appear showing the name of the file you just downloaded with an option to “Open in an app and a second line labeled “More.” If the default choice is not the app you want, then tap “More” for more choices and slide the top row of icons until the app you want appears and tap the icon.
- When asked "Import User Data?", click "Import". You will get a success screen.
- See below for further instructions for typical apps.

For AquaMap:
  - The first time you load the route, it will automatically appear, ready for navigation. To reaccess it after the first download, follow the instructions below.
  - Tap on the search icon to the upper, right of the screen.
  - Tap on User Data.
  - The route you imported will be in the list shown, scroll until you find the route.
  - Tap on the route name and it will be shown on the chart ready for navigation.

For iNavX:
- Tap on Routes at the bottom of the screen if the routes screen is not already shown
- Tap on the route just imported
- Tap on Scroll To for the route to be shown on a chart

For Garmin Bluechart:  (no longer offered)
- Tap on the ship’s wheel icon at the bottom, middle of the screen
- A screen showing “My Content” will pop up
- Tap on “Routes”
- A list of routes will be displayed, tap on the one you want to use
- Tap on the “Hamburger” icon at the upper right (three horizontal bars)
 - One choice will be to “View on Chart”, tap on that choice to see the route for navigation.

For Garmin Active Captain:
- Tap the Chart tab at the top of the screen
- Tap the "Hamburger" icon at the top left
- Tap User Data
- Find your downloaded route and tap on View on Chart

For Downloading the GPX file to your computer
- Click on the GPX file link.
- The downloaded file will appear at the bottom left of the window. It has already been saved in your default download location per your Windows preferences, it’s usually a folder called “Downloads.” You have to know this location so you can access it for copying the file to your PC navigation program. A Mac computer has a similar feature.
- Open your PC navigation program and import the GPX file.

To transfer a GPX file from a computer to an iPad:
- Attach the GPX file to an email addressed to yourself.
- Open email on your iPad and hold your finger on the file icon, a menu will appear.
- Slide the top menu to the left and tap on the app you wish to use.
- If you’re asked to okay the import, tap Yes.

Other apps have different ways of accessing routes but once the route is loaded into the app, all you have to do is find the route in the various menus.
