Are you struggling to trim your sails and to see your tell tales? Thanks to the recently added e-Tell Tales integration, our displays enable you to monitor your upwind sails' aerodynamic efficiency. Real-time, night and day in all weather conditions. The data from Mer Agitées sensors are presented in a very comprehensible graph, so the performance of your sails is crystal clear. Sailmon can supply sensors and a control box together with the software integrated into your E4 processor needed for visualisation on your screens. Please contact us for more info.
