Coach's Debrief

What happened and what it cost

This race

▶ Speed toward the mark by sailing angle

▶What is this?

This shows how efficiently you sailed at different angles to the wind. Higher VMC (velocity made good on course) means you're covering ground toward the mark faster. The table breaks your sailing into angle bands so you can see which angles worked best and which cost you speed. The scatter view plots every data point so you can spot patterns.

Coach reads this as

GPS-inferred VMC by TWA band · downwind legs only

TWA approximate — treat as zones not precise values

TWA Band	Rows	Avg SOG	Avg VMC	VMC/SOG	vs Baseline	Reading

▶ Tacks & gybes

▶What is this?

Every time you changed direction — tacking upwind or gybing downwind — is logged here with how much speed you lost through the turn and how quickly you recovered. Good boat handling means less speed lost and faster recovery. Patterns here reveal whether your turns are costing you more than they should.

▶ Sailing angles and laylines

▶What is this?

This shows the angles you actually sailed compared to your boat's optimal angles in these wind conditions. Sailing too high (pinching) or too low (footing) upwind, or too deep or too high downwind, costs distance to the mark. As you upload more races, your boat's optimal angles become more accurate — the system learns how your boat sails.
