These routings will first be simplified so that everyone can use them. In a second time, we will set up more elaborate routings that will allow us to determine long-term strategies…"

A new evolution for the two leaders in navigation applications, weather and routing on mobile devices, which should allow them to popularize their applications to a large audience, and perhaps spark vocations among the large number of players who have never been on the water before.

Navigation applications are full of acronyms. This coded and cryptic language was originally developed for electronic navigation instruments, GPS mapping and other chartplotters. These acronyms, in the form of three letters most often, are the contraction of terms defining specific navigation data and according functions. This facilitates on-screen display taking few space. While some of these acronyms are relatively well assimilated by the boater, as SOG for Speed ​​Over Ground (SOG), you can quickly access subtleties that are not always mastered as COG for Course Over Ground, meaning "route runned on the ground", that the word "Course" in English can mean "Route" or "Heading" according to the context.
