Debrief
Turn a session into something you can actually understand while it is still fresh, whether you are reviewing alone, with others, or with a coach.
A simple debrief flow
- Open the session
Load the track on a tablet or laptop while it is still fresh.
- Pick 1–2 moments
Choose the clearest examples — starts, mark roundings, manoeuvres, or a key decision.
- Replay and compare
Use the timeline to replay and compare boats from the same session. Look at differences in line, timing, and decisions.
- Agree one takeaway
Keep it calm: agree what happened, then choose one change to try next session.

Common questions
-
Do we need every boat to record?
No. One or two boats can still be useful. It becomes more valuable as more boats take part because comparison drives discussion.
-
How do we keep the debrief calm?
Pick 1–2 moments to focus on, and agree one takeaway for the next session.
-
What makes comparisons useful?
“Same session, same conditions” comparisons are the most repeatable. Look for patterns rather than single spikes.
-
What should we review first?
Start with the clearest objective moment: a start, a rounding, a manoeuvre, or a key decision point.
