Race Replay Sessions
Race results tell you who won.
Race replay shows you why.
TracTracUK race replay sessions transform high-resolution GPS tracking into powerful performance insight for dinghy racing. By analysing boat speed, course over ground (COG), and VMG, we reveal the small decisions and execution details that decide races—often by only a few boat lengths.
This isn’t just tracking.
It’s racing intelligence.
Our race replay sessions use professional-grade, high-frequency GPS data captured directly from the racecourse. Every tack, gybe, acceleration, and speed change is recorded with exceptional accuracy.

See the race through the eyes of the winners
Race replay allows sailors to compare boats side-by-side and answer the questions that matter most:
Where was speed made—or lost?
Who accelerated best off the line?
Which lane paid upwind?
How did the leading boat protect or extend its advantage?
What actually happened at that crucial mark rounding?
By syncing multiple boats in real time, every phase of the race can be reviewed moment by moment, making it clear how the winning strategy was executed.

Your TractracUK race replay questions, answered
-
From “What Happened?” to “What Do I Do Next Time?”
The real value of race replay isn’t just analysis—it’s application.
By clearly showing how races are won, sailors leave with:
Practical tactical takeaways
Better understanding of speed and mode
Clearer decision-making under pressure
Confidence built on evidence, not guesswork
Every replay session bridges the gap between theory and performance on the water.
-
Race replay sessions are ideal for:
Club racing debriefs
Open meetings and championships
Squad and pathway training
Coach-led performance reviews
Post-event learning sessions
Whether it’s a single race or a full series, replay sessions turn racing into a shared learning experience that accelerates improvement.
-
VMG measures how quickly you are moving towards the next mark, not just how fast the boat is going through the water.
You can be:
Sailing fast but inefficiently, or
Sailing slower through the water but arriving sooner
VMG tells you which one actually wins races.
-
Compare where boats actually went versus where they intended to go. COG reveals tactical positioning, layline judgement, and fleet separation.
All metrics are visual, intuitive, and easy to discuss—perfect for group learning.
-
Race replay sessions work because they:
Turn complex races into understandable stories
Show how races are won, not just who won
Accelerate learning for individuals and fleets
Build shared understanding between sailors and coaches
High-resolution tracking provides the data.
Race replay turns it into performance. -
We host the session, and the race is then replayed on screen, with boats moving exactly as they did on the water.
During the replay, you can:
Pause, rewind, and fast-forward
Zoom into key moments
Switch between race legs
Follow individual boats or the fleet
See course geometry, we measure line bias, distance and bearings to every mark
This instantly brings back context that’s often lost after racing — pressure lines, fleet splits, and decision points become obvious.
-
If you want sailors to understand why races are won—not just who won them—race replay is the fastest, clearest way to get there.

TracTracUK — See the race. Understand the result. Sail faster next time.
-
Boats can be directly compared to show:
Who had better VMG, when and why
How mode choices differed
Where one boat gained meters while another stalled
Why the winning boat pulled away
This removes opinion and replaces it with evidence-based learning. description
