Why KnotNow Sessions
Master your marginal gains
Most sailors rely on feeling fast. But feeling fast isn't always being fast. Our smart software 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.
Efficiency and speed
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. Our analytics ensure that every session leads to progression.
- For Wing Foilers: Diagnose the hidden asymmetry between your heel and toeside transitions. Perfect your flight consistency across every gybe.
- For Dinghy & Skiff Sailors: Sharpen your VMG and analyse your "distance lost" in every manoeuvre. Perfect your tacking angles to climb the ladder faster.
- For Windsurfers & Down-winders: Track your speeds per interval and velocity made good. Understand how your speed correlates to your bearing across the full wind compass.
- For All Sailors: From offshore cruisers to weekend racers – if you can track it, we can analyse it. Understand your craft's true pointing ability with hard data.
Eliminate guesswork
The real power lies in the comparison. KnotNow ranks your achievements across every session you've ever uploaded. See your 5-second max speed improve month-on-month or watch your upwind progress score climb as your technique sharpens.
