There is nothing -- absolute NOTHING -- half so much worth doing
as simply messing-about in boats.

We have been loaned a satelite tracker for the Everglades Challenge and it will be turned on Saturday morning.

For anyone interested in tracking us during the race you can log onto http://www.gwvas.com/gwvas/login <http://66.46.215.163/>

 Click on "Asset Management System"

Enter "traveler" for Login Name

Enter "journey" for Password

(both must be typed in all lower case letters and do not type the quotation marks).

Click on "Login"

You are now logged into the Travelers Account on the site and should see a "Welcome to GlobalWave.com" page in the middle of the window and there should be 8 options at the top of the window

View the current position of a boat:

 At the top of the window click on "View Messages"

The term "Travelers" will appear in the left margin.  This is the name of the fleet of boats being tracked.  Click on "Travelers"

The names of 3 boats will now appear in the left margin and the latest position report for each boat will appear in the center of the page.  In the position report line is the description of the nearest landmark and the word "map".   Note also certain other parameters of the boat (e.g., temperature) are displayed within the position report.

To view the position of a boat on a map, click the term "map" on that boat's current position report.  The map will be opened in a new window and will appear at the lowest resolution (i.e., ½ of North America).  The boat will be identified on the map with a red truck symbol with the name to the side. To zoom in, click on one of the numbers above the map.   When finished viewing the map, close the map window by clicking on the "X" in the upper right corner.

View the last 10 positions for a boat:

To view the last 10 reports for a boat click on the boat's name (e.g., * SouthernSkimmer*) in the left margin.  The last 10 reports from that boat will appear in the center of the window.

You can now click on "map" on any of the position reports.

If you click on "Asset Route Map" (in the center frame, above the position reports), a map window will be opened showing the location of the last 10 reports.  This is like a track of the vessel's progress.


Note about tracks:  if the vessel is in the same location when two or more position reports were generated, only one of the reports will show on the map.  Thus, you may only see a few positions plotted on the map.  Also, if the vessel is traveling fast between reports, the track of plots on the map may be so spread out that the first map to be displayed may not cover all the positions -  you may have to zoom out.

Note about position reports:  position reports can be generated at various intervals.  The most common frequency is 2 times per 24 hours, however it could be as frequent as every 3 minutes.  The frequency is controlled by the owner of the boat and can be changed at any time.  It is common to have the frequency set to 1 or 2 per day when the boat is "on the hard" or at dock for several days and then set to 4 to 12 per day when making a passage.   Also, position reports can be blocked if the terminal on the boat cannot "see" satellites in the sky (i.e., inside a metal building or up against tall trees or buildings).  So, be sure to notice the date and time on the current position report to know how old the data is.

Thanks Graham. I see your position at 54 minutes after the start is on a truck surrounded by blue in the middle of the Gulf of Mexico.  Laughing

Actually, the map function will show the track but doesn't give reference to the coast (unless there is road nearby). Does anyone know how to plot the positions on a chart so we could all see it?

Zoom out several numbers and it will show the truck relative to the coast crossing the entrance to Tampa Bay.  Successive locations will show on the map, letting you see his progress.

On the map, I clicked on number six and it shows the coast and his position.  I see his position as being just about Anna Maria Island which along the land is Cortez Florida.

Someone posted this link on the Duckworks site. It's a Google Earth map based on Southern Skimmer's tracking data. The link is:

http://www.pdmartin.pwp.b...o.uk/SouthernSkimmer.html

The data is several hours old so it only shows tha track up to just north of Englewood.

Surprised to disover that that Google track predicts the future--right now it's reporting the boat's position as of 8pm tonight!  Actually, if you zoom in and hold the cursor over a position you will get the time of the fix, but the real fix will be 3 hours (EDT) earlier than that shown on the map.  It's fascinating to zoom way in and look at the maze of shoal water and marsh (?) they are threading through on the way to Chokaloskee!
