Fastrrr uses a unique, innovative telemetry system that helps leisure sailors learn and help the professionals to achieve maximum performance. It measures and analyzes real-time values of the sailboat and other environmental factors to give a full picture of the boats performance under various conditions.In a gradual way, with the new trends (Big Data, Artificial Intelligence), the demand for these types of technologies is grown in sailing sport. Compared to some other sports, sailing is still a bit behind - although it is a technical sport - but the first signs are just started to appear of this new approach.In the big series like Volvo Ocean Race, Americas Cup (without the need for completeness), there is one dedicated person from the team who works with data analysis and processing. Teams are typically set up their own tools and procedures what they need to do because there are no players on the market to provide such services.There is no doubt, the widespread use of innovative technology in the field of sport is just a matter of time.For sailors, one of the most important things is how fast and what angle could their boat be sailed in certain wind conditions.After capturing large amounts of data and evaluation supported by artificial intelligence, different targets can be defined, which will later give feedback about the competitor's current performance.
