You said “Medicane” ?
The numerous sailors who crisscross the “Big Blue” have known for ages that, if navigation is relatively easy, meteorology represents a particularly difficult constraint to understand. Indeed, if the coasts are mostly steep and the dangers very localized, if the tides are almost negligible, if currents are only to be taken into account in well-defined areas, the major difficulty comes from capricious weather, difficult to predict, can represent a real danger due to its changing moods, sudden, even brutal.

SailGrib WR adopts Geogarage maps
Collaboration is progressing between SailGrib et Weather4D. The recent version SailGrib WR 6.0 adds support for platform maps Geogarage including the international catalogs of SHOM and UKHO from around twenty publishers. These “tiled” raster maps are mainly based on digital data from official hydrographic services., or more than 10.000 maps available today, and viewable on their interactive catalog.
Unlike the majority of private providers, Geogarage offers subscriptions by publisher, and not by geographical area (¹). These are renewable annual subscriptions allowing regular updates. The icing on the cake is the pooling of subscriptions between Android and iOS devices : an account created on the Geogarage platform allows you to download subscribed maps to an iPad with Weather4D Routing & Navigation and an Android smartphone with SailGrib WR, or conversely an Android tablet and an iPhone with their respective application, up to five different devices.

Routing : from game to reality
On the second day of racing of this Vendée Globe 2020, we can say that the weather conditions that the skippers will experience on the descent towards the Doldrums will be particularly tough. After leaving in lousy weather, a first not very active cold front passed without incident, the loners will cross a second, much more violent front during the night and morning from Tuesday to Wednesday, for the group going to the West, and in the evening for the group passed between the DST (¹) and la in French.
But these future conditions are very different for Virtual Regatta players and for sailors… Read more …
Android Marine sets sail for the Vendée Globe 2020
Oh yes, everything happens ! In my entire computer-nautical career I had never played any computer game whatsoever., not even the historic Windows card game that cost businesses thousands of idle office hours… but you should never say : Never !
Or donc, here I am registered for Virtual Regatta, one among the most 340.000 players registered at this time, ready to start the Vendée Globe tomorrow at 1:02 p.m.. Like any beginner, I watched a few videos to quickly understand this game, Who, we are all, seems relatively simple for an experienced sailor. But from there to playing in the big leagues, there are still several oceans to cross !
