Turn analysis

Whether you’re rolling a dinghy, carving a foil, or throwing a gybe on a windsurfer, every manoeuvre trades forward motion for a change of direction. KnotNow isolates each tack and gybe so you can see speed in versus speed out, how much ground you gave away, and a smoothness score that reflects how well you carried momentum through the turn.

For racers, that’s the difference between defending a lane and getting rolled at the mark. For weekend sailors, it’s a clear read on whether a hesitant exit or a late sheet/foot change cost you boat lengths - or board lengths - you didn’t feel on the water.

• Ground lost - distance cost through the manoeuvre, split where it helps you compare port and starboard.
• Smoothness - a single efficiency signal from your session data, so you can compare turns session to session.
• Speed through the turn - see where you bled speed and where you got back up to pace.

Use it as a tactical debrief: when the data says a tack cost more than the shift was worth, you’ll know - and you’ll know what to work on next.
