Adrena

ADRENA is a specialized software company based near Nantes, France, focusing on high-performance navigation and tactical analysis. Since its founding, the company has developed an evolving suite of products, including Octopus, First, and Pro, tailored for both recreational cruising and competitive regattas.

A key innovation is the Optima Pro software, which generates precise speed polars and performance studies based on actual recorded data. The integration of the Sailect function, developed with North Sails, further enables navigators to map and analyze the effective range of their sails.

The company is widely recognized for its powerful routing calculation modules and tactical decision-making tools. These systems allow skippers to manage GRIB weather files and perform real-time performance analysis to optimize their course during a voyage.

In addition to performance, the software includes critical safety features such as AIS integration, Man Overboard (MOB) protocols, and automated alarms. This comprehensive technical approach ensures that sailors at all levels can navigate with both efficiency and security.
