Esa Regatta Watch is the first smartwatch with an application specifically designed for sail and regatta, able

to provide all the information on boat’s performances with a professional level, in a simple, direct and

completely automatic way right on your wrist.

esa provides the comparison of the actual performance respect to the target, provides all data for a winning start,

works as a repeater for the onboard instrumentation data, records navigation data al allows a further editing of them.

esa is an instrument useful at every level:

- for the beginners who wants to improve the basic setting of his sails, both in cruise and regatta;

- for the racers which searches for the best performances on his boat without renouncing to use a professional

instrumentation that usually has much higher costs and complexity respect to esa.

Thankfully to the extreme portability is possible to access to all performance and navigation data of the boat in any

position onboard!

esa is connected to onboard instrumentation through Wi-Fi connection which transmits NMEA0183 data.

The following instruction will let also the beginners to use easily esa app

CAUTIONS

In order esa to work properly and to let work it at the maximum potential is important to have onboard

instrumentation calibrated.

For its own calculation esa imports from onboard instrumentation a series of essentials data that elaborates on its

own: Boat Speed (BS), Magnetic Heading (HDG), Apparent Wind Angle (AWA) and True Wind Angle (TWA).

We recommend to carefully read the instruction of yours navigation system and to perform the data calibration of those mentioned above

as written in their manual. Calibration values could change through time, is better to check them periodically to be ensured the onboard

instrumentation and consequently esa work properly.

It is better to learn the meaning of the abbreviations comparing in esa displays.
