After completing a weather route on your Raymarine Offshore App, you can export it in a GPX format to your GPS or Navigation software. GPX is a standard format for transferring waypoints between programs.
All 4 weather routes, PWG, PWE, GFS and ECMWF can be exported; however, we recommend that you export the active route.
Set your Waypoints in the Offshore App for departure and destination.
Download the latest GRIBs and weather routes.
Go to the Waypoints icon on the map and add waypoints to your route by tapping the + plus symbol.
On the map, move the new waypoints to a position that averages the 4 routes or follows the majority of the routes if there is not consensus.
Tap on Tables.
Tap across to Export.
Select your route to be exported from; Select Route: My waypoints; this is the route averaged over the 4 routes.
Tap Export as GPX.
On the Raymarine MFD you will need to save the route to an SD card and then open it from the Chart menu or Navionics.
The route has to be transferred to a microSD card that is inserted in the Raymarine Axiom. If there is no SD inserted, then there will be nowhere to open the route from. If you do have an SD card, the route will save straight away, and a message will show on the screen saying it was successful. If it doesn't work, try the other SD card slot. Once saved to the SD card, the route can be opened in the Chart App.
Tap on the Menu icon
Tap Waypoints, Routes, Tracks then Import/Export > Import from card
Choose the SD card from the list
Navigate to the PredictWind Folder and choose the route file.
Alternatively, what many people do is download their weather route on a laptop or iPad.
Look at where they are going to be heading over the next 12 hours.
Tap on the screen to see the significant lat lon waypoints in the pop-up box along the route, and enter them manually into the chart plotter as go-to waypoints.
Then use the chart plotter to navigate the next 12 hours.
After 12 hours, run another weather route with the updated start position at the time, and do the same again.
It shouldn't take more than 5 minutes to enter a few waypoints, and you are getting the latest weather route from the updated forecast models, which is the key to a safe weather route.
