Where can I find a real nautical chart on the system ?
Avalon Offshore is now also a plotting software. You will find about 900 public raster charts in the Cartography menu. You can also load your private raster charts in the device to be used offline. Avalon has a also GPX interface to export the computed route into the main plotting softwares ( OpenCPN, Navionics, …)
I have set up my arrival point behind a cape (or in a bay) and Avalon does not find a suitable route. Why ?
You need to enter a waypoint to help Avalon. Avalon works like a GPS. When you arrival point is behind a cape, you need first to head towards the cape and then to the arrival point.
It is the same with Avalon, you need to add a waypoint at the cape. Avalon will then calculate 2 (or more) route segments: from your current position to the waypoint and then from the waypoint to the arrival point.
I am sailing in the channel where coastal currents are very strong, but the system does not provide them.
The coastal currents are provided for the zone Iberia, Biscay Ireland as a pay-in option for both the Coastal and the Offshore version.
I cannot find my boat in the database of polars.
We have added many boats in the last days and will be pleased to add yours too. Just fill in a polar request form on the main page and we will create a new boat entry in our database.
There is another option: you can also create your own polar file (using the “.pol format”), download it to your android device. Then you can open the polar file with Avalon.
I have defined waypoint(s) but Avalon does not find any route.
This can happen when waypoints are too close to other waypoints, starting point or arrival point. When this is the case, Avalon will consider that one or several points are already validated, will jump over the (already validated) waypoint’s) and try to calculate a route to the next wayypoint.
In the latest releases of Avalon, a check is made and a warning displayed when this is the case. It prevents the route to be calculated before a correction is made.
There are 2 ways to solve that problem: Either you move the waypoints or you decrease the waypoint size in the “compute route” settings.
What is the meaning of the colors on the route points ?
The colors indicates:
- Pink: Port tack
- Cyan: Starboard tack
- Motorboat: Engine is on
(Assumes marker toggle in on and enough zoom on the map)
I cannot load my own navigational maps in the device.
The loading process needs to be done online. Once loaded, the maps are available permanently offline. The main steps are:
- Send your map(s) to your gmail account.
- Open your email on the device. Click on “save” to store the map (do not click on “save to drive”)
- Open Avalon offshore and go to the Nautical Charts menu
- Load private charts
- Select the chart to install
- Allow for 1 or 2 minutes for the chart to be processed and installed on the device
- Now the chart is availble for use in Avalon without any connection
I have purchased the Advanced Routing option but I cannot calculate routes above 72 hours. Why ?
This is because you have to specify a longer “Travel Time” in the settings. In the offshore version, this parameter is defaulted to 72 hours. You can go up to 180 hours. This parameter is used by the system to download only necessary winds and save network data transfer.
