Master your marginal gains
Most sailors rely on feeling fast. But feeling fast isn't always being fast. KnotNow processes your GPS data to reveal the marginal gains that win races and master foils.
"Data is the only way to eliminate the 'good side' bias. If you can measure it, you can fix it."
Turn the track into decisions
Competitive sailors don't just replay the race in their heads — they debrief with evidence. KnotNow turns a GPX or TCX export into course segments, tack and gybe quality, and upwind VMG so your next session starts with a plan, not a hunch.
Designed for every discipline
Whether you're pushing the limits of your wing foil, carving through a downwind swell, or perfecting your VMG in a dinghy, every session is a chance to get faster.
- For wing foilers: Diagnose asymmetry between heel and toeside transitions. Perfect flight consistency across every gybe.
- For dinghy & skiff sailors: Sharpen VMG and analyse distance lost in every manoeuvre. Perfect tacking angles to climb the ladder faster.
- For windsurfers & down-winders: Track speeds per interval and velocity made good across the wind compass.
- For all sailors: From offshore cruisers to weekend racers — if you can track it, we can analyse it.
Progress is the metric
The real power lies in the comparison. KnotNow ranks your achievements across every session you've uploaded. See your 5-second max speed improve month-on-month or watch your upwind progress score climb as your technique sharpens.
