The 1720 Sportsboat class is embracing technological innovations in sailing to enhance its development and offer live tracking for the National Championships for the first time.

Spectators and supporters worldwide can view this live tracking in the Sailmon App., Sailmon, The 1720 Sportsboat Class, and Waterford Harbour Sailing Club, have collaborated to bring this remarkable improvement to the 1720 Sportsboat Nationals this month.

High-accurate tracking thanks to MAX Mini

The revolutionary Sailmon MAX Mini will facilitate the tracking. The MAX Mini comes with an integrated SIM card offering global IoT coverage with 2G fallback. It ensures high accuracy down to centimetres, thanks to industry-leading sensors. With support for five GNSS constellations (GPS, GLONASS, Galileo, BeiDou, QZSS & SBAS), it guarantees high-precision recording and replay of sailing data with 25Hz sensors (data is recorded in the cloud at 1Hz). The unit will automatically transmit all data to the Sailmon App.

Kenny Rumball of, the distributor of Sailmon products in Ireland, commented, "We conducted a small trial of this system with the RS21 class earlier this year as part of the Dun Laoghaire regatta. It clearly demonstrated how sailing can now engage spectators on land and provide answers to questions that sailors constantly have, such as whether I was as fast today as usual or if that other boat was faster. We genuinely believe that the Sailmon MAX Mini represents the future, and we hope to offer this system to all racing classes throughout Ireland for the 2024 season."

Sailmon App delivers instant debriefing

Data from all competitors will be instantly available in the Sailmon App, offering unique opportunities for friends, spectators, family, and coaches to relive the races for both fun and analytical purposes. The primary goal of the class is to utilize this high-quality data to enhance competitiveness by comparing race data and facilitating group discussions after sailing. This enables the support team to quickly show the various data differences among different boats in the fleet. It is hoped that this will improve fleet performance and, with spot prizes available, reveal who truly excelled at the start or which boat was the fastest upwind. After all, numbers don't lie!

Julian Hughes of Waterford Harbour Sailing Club "WHSC are excited and grateful to have Sailmon and Marine Services support for the 1720 Nationals to help us make the post race discussion more engaging and fun, having real tangible data to offer prizes for the fastest upwind and downwind sailors along with other areas such as starting will add fun to the daily prize giving. With over 25 boats expected to take the line in Dunmore East, we are looking forward to welcoming the fleet to Dunmore"
