The most powerful and interactive weather station for sail coaches

Improve your professional performance, converting your motor boat in a complete and autonomous weather station, the ideal for real-time monitoring of the race course conditions.

Get all the data from the race course always at your disposal: esa coach is an advanced and innovative kit specially designed for the motorboat of coaches, that allows monitoring and analysis of wind and current conditions in real-time, and provides the recorded data for an efficient consultation at the end of the session.
With esa coach you can constantly check the reliability of the day weather forecasts, and take advantage from every change in a winning way.
Thanks to the powerful and innovative calculation and data management algorithms, esa Coach is able to create an history of the training or race sessions; so, all the data can be consulted in real time or at a later time, for a regular updating and for a perfect debriefing at the end of the day.

How it’s made

Carbon fiber mast: light and resistant and easy to mount and transport.
Wind Sensor: fast connection for wind sensor with the mast. Easy to remove by night and re mount at the morning.
GPS: esa coach is provided with internal high frequency gps for the best precision in position measurement.
Compass: The best solution with a gyroscopic compass, for the best precision during movement of the boat.

Thanks to this system, all the training data are available in real time, directly on your boat.
Consult all the data directly on your device through the Wi-Fi transmission. All data collected and processed by the control unit are available on the esa Coach dedicated app.


With log installation you can have real time measurement of current and depth of the training fields. It is possible to measure the current using the app and exclusive esa-coach with the “currentmeter”: launch current meter close to the starting line for instance and move away. After 2-3 minutes recover the current meter ant stop the recording. The app will calculate the current on the field in this crucial point.

Verify if the forecast are true directly on field.
Get every drop or change of the direction of the wind looking at the graph with the tendencies: anticipates any tendency of rotation or intensity at a glance.
Esa coach app shows the wind direction and its intensity at the same time, on graphics with media, extremes and variations available for different time intervals, that can be selected by the users according to their needs.

Instruments Panel: The app allows to visualize all the data coming from the sensors, selecting them individually to monitor the most important data for the user.
