Octobre 27, 2014: Advanced Routing and Weather Forecast options are now available on Avalon Offshore version.

Those options can be subscribed from the Avalon main menu settings on the device. There is a one month free trial period up to Dec 31st 2014 (cancellable at any time).

Additional features are:

  • Routeing on 180 hours
  • Streams (MyOcean) on 5 days (Europe zone)
  • Analysis of waves all along the cruise
  • Analysis of winds all along the cruise
  • Weather forecast display for every route point.

On the 2 versions (coastal and offshore, we have also added Stopover Management. Even during a one day cruise, it can be very useful when you want to stay at anchor for a couple of hours and still be sure to be back to the marina before the tide gate closes.  It is not very useful to offshore racers but we consider that a route planner should also bring comfort and safety to the yachtsman.

Analyse of waves along the cruise:

  • Sea-state summary (top right)
  • Wave and swell heigth with slider bar to select time
  • The 3 circles (bottom right) shows the directions of the waves (combine waves, swell and wind waves) compared to the heading of the boat.

Oct 3, 2014: New release of Avalon Coastal (V1.8.1)

We have added a set of new reports providing a synthetic view of the cruise.

The objective of this summary report is to give the skipper and crew a quick view of the sailing conditions so that he/she can quickly approve or reject the proposed route and/or timing.

Please note that there is an option in the settings to select if the summary reports should be displayed before the route on the map or after.


In a couple of weeks, we will release a set of much more complete summary reports on the Offshore version.
