Sailing analytics

Turn GPS tracks into clear sailing insight.

TillerWise gives competitive sailors a fast, visual post-session review with sailing-specific metrics, weather context, and coaching takeaways. Upload a GPS track after training, replay the session, and see where VMG, manoeuvres, and pace changed.

Review workflow

A debrief loop for sailors who want more than a track map.

Generic fitness dashboards and track maps can show where you went and how fast you moved. TillerWise is built around the questions sailors ask after training: which legs held pace, where did manoeuvres cost distance, and which changes are worth testing next time?

01

Import the track

Upload files from a watch, GPS logger, onboard tracker, or Strava activity without rebuilding the session in a spreadsheet.

02

Review the sailing context

Use the replay map, weather enrichment, heading changes, and point-of-sail distribution to understand what the track actually represents.

03

Choose the next drill

Turn VMG trends, tack losses, and pace changes into one or two specific actions for the next training session.

What TillerWise helps you inspect

  • Sailing GPS track analysis for GPX, FIT, KML, and TCX files.
  • VMG review for upwind and downwind work with weather context.
  • Tack and gybe quality checks that focus on repeatable losses.
  • Session comparisons that show whether changes hold up over time.
  • A clearer alternative to rebuilding every review from screenshots, spreadsheets, and scattered notes.

Built for repeatable improvement

A single sailing session can explain what happened that day. A library of reviewed sessions shows whether a technique change, trim decision, or training block is actually improving. Use each upload as a reference point, then compare similar sessions as your season develops.
