SailSync helps sailors, teams, and coaches turn time on the water into better performance. Record together, follow regattas, replay races in 3D, compare maneuvers, and explore your sailing data with FLO, your AI sailing assistant. Start with Standard, free: record sessions with up to 10 boats and review your sailing with included session analytics. REPLAY THE RACE IN 2D OR 3D See how the race unfolded. Follow individual boats, explore different camera angles, or let Auto mode follow the leaders. Review live standings, boat trails, and tactical overlays—including bad air—to understand the fleet around you. REVIEW AND COMPARE YOUR MANEUVERS Take a closer look at your tacks and gybes with dedicated 3D maneuver review and synchronized speed-over-ground and VMG plots. Compare up to five maneuvers from your own boat or different sailors. Align turns in a shared 3D view, examine their paths, and see how speed changes through each maneuver. Explore average and top-quarter traces, compare race averages, and choose exactly what you rank by: maneuver loss, minimum speed, average speed, or average VMG. GPS coverage indicators help you understand where the recorded data is complete and where gaps affect your review.
