A fixed view of all 20 boats at the published start. Hull positions use each boat’s nearest actual observation. This view stays still while the replay runs.

Gold line: observed committee and pin. Hulls enlarged for visibility. Negative distance is the assumed pre-start side; these GPS measurements do not decide official OCS.

Launch report / first two minutes

Off the line: acceleration and lane holding

Each boat’s clock starts at its first forward crossing of the line near the gun. Speeds are recent GPS ground speeds. The lane is a corridor about one boat length either side of the initial course. This is a geometric corridor.

Reference speed: 6.5 kt, the boat’s own typical speed in the minute or two after crossing. Reaching that speed is judged over a sustained period. The shaded lane extends about one boat length (11.28 m) either side; a sustained departure may be an intentional turn. Valid coverage: 41/41 samples.

Approach to the line

Megan Thomson near the published gun. The line follows the recorded committee and pin positions. Negative distance means the assumed pre-start side; these measurements do not determine official OCS.

The speed comparison covered 1,218 boat-minutes against comparisons against peers on similar courses. 20 slower windows were found for this boat. They are review candidates, not attributed race losses.

04 / Fleet comparisons

Slower windows that survive stricter checks

Nearby boats, aligned observations and similar courses. 49 windows across the fleet remain below peers under every screening setting; 137 candidates were set aside. Select a window to replay it.

The range describes sensitivity to screening settings, not statistical confidence. Wind, tack and clear air are unverified.

05 / Mark reference

Velocity toward Mark 1

GPS velocity projected toward the recorded position of Mark 1. Positive values approach that mark; negative values move away. Mark 1 remains the reference throughout, including legs sailed away from it; this is not wind VMG or automatic leg assignment.

07 / Analysis coverage

What this recording can establish

The analysis runs on the complete retained fleet recording. Start geometry, ground speed, comparisons with similar courses, stable lineups and velocity toward Mark 1 are available. The following analyses need additional evidence.

Wind, VMG and line bias: No measured wind direction or speed in this position-only acquisition.
Tacks, gybes and maneuver recovery: No measured TWA or boat speed through water. GPS course changes alone do not identify tacks or gybes.
Polar targets and matched performance: Requires measured BSP, TWA and TWS channels.
Wind-frame gain/loss and calibration: Requires independently sourced wind and heading reference channels.
Leg splits, finish ranking and official OCS: The recording end is not a finish time. Validated per-boat mark passages and official results are not included.

Source and calculation details

Public TracTrac replay

Coordinates and timestamps are retained at source precision. Ground speed is derived from successive GPS positions, and gaps in the recording are left out rather than filled. Analysis runs from the published gun to recording end, which includes any movement after finishing.

Peer comparisons use short time windows against similarly sailing boats. Stable lineups add checks on proximity, timing and sensitivity to screening settings. Adjacent windows are not independent trials.

Primary series uses approximate mark positions near each observation.

Observed drift is not a bound on unseen motion or GPS error.

Fleet-side estimate is retrospective and is not wind, tack or target-mark identification.

Near-gun means nearest actual observation; inspect its timestamp rather than presenting it as a gun-time measurement.
