Flight metrics
NewStop Winging it. Master Your Foil Time
Celebrate every minute on foil.
From your first sustained flights to marathon sessions, track total time and distance on foil — and the share of the session spent above the water.
- Track your time in the air. Watch foiling percentage climb session after session.
- Port vs starboard. Compare foil times on each tack and dial in your weaker side.
- Equipment testing. See what moved the needle when you changed stabiliser, wing, or pumping strategy.
Progress loves a baseline. Celebrate every session that moves you closer to sustained flight or fewer steps on the shoreline.
- Seeing exactly how much time and distance you spent walking back to the launch is the ultimate confidence booster. Compare today’s session to last month’s and prove you’re holding your ground better every time you ride.
- Upwind KPIs — watch angles and VMG creep as fundamentals click.
- Confidence loop — show up next time knowing what objectively improved.
Race ready? You will be.
When you record your sailing, it’s easy to get lost in the noise — line bias checks, pre-start practice, chats between races, or the slow beat back to shore.
With Races in KnotNow, edit your recorded session just like cropping a video on your phone:
- Drag the timeline to your exact start and finish times.
- Trim out breaks and non-racing sections.
- Hit Apply to break the session down completely — by race or by leg.
Track the season in Race Logbook, with racing and training kept separate. Racing — sorted. Now you’ve just got to get higher up the fleet.
Don't miss how you sailed. Stack sessions in the logbook, rank them with leaderboard presets, and let achievements surface the breakthroughs worth repeating.
- Searchable logbook — every upload in one sortable stream.
- Leaderboard lenses — overall, upwind, manoeuvres, speed columns on demand.
- Milestones that stick — foil time PBs, walk-back trends, tactical wins worth sharing.
