DATA

The 4-hourly report: 00:00, 04:00, 08:00, 12:00, 16:00 or 20:00 UTC. On Standing, the newest report in the file; the row covers the 24 hours that end at it.

The UTC day that was sailed. The row covers its 24 hours and closes at the 00:00 UTC report that follows.

GGR’s numbering: 6 September is day 0.

The report that closes the row.

YB’s number for the boat; the same in every file.

The skipper’s name.

The yacht’s name.

The boat’s design.

Three-letter country code.

Rank by YB’s distance to finish at the report.

Places gained (+) or lost (−) since the report 24 hours earlier.

Distance to finish, measured by YB along its course line. YB redrew the line on 22 September 2026, 844 nm longer from Trindade on, and recomputed its track; every figure here is on the new line.

This boat’s distance to finish minus the leader’s.

The same to the boat one place ahead. Blank for the leader.

Latitude of the boat’s fix at the report, decimal degrees, north positive. A real fix from YB, never interpolated.

Longitude of the same fix, decimal degrees, east positive.

The true time of that fix. Trackers do not all report on the second.

FALSE when the boat missed this report: the position is then her last known one, with its older time, and the columns about the last 24 hours and 7 days are blank.

Great-circle distance of the 4-hour leg that ends at this report. Blank: no fix at one end.

That distance divided by the time between the two fixes: average speed over the ground.

Speed made good toward the finish on the leg.

The bearing from the leg’s first fix to its second. Not the heading.

Latitude at the start of the 24 hours (the fix 24 hours earlier). Blank if either report was missed.

Longitude at the start of the 24 hours.

Miles sailed along the track over the six 4-hour legs of the 24 hours.

How many of the six 4-hour legs have a fix at both ends. With fewer than 6 the run holds a straight line across the silent stretch: a lower bound. Filter on 6 for clean runs.

TRUE when the tracker missed a report in the 24 hours of the run: across it the boat is credited with a straight line, and if it was the first report of the 24 hours the run begins at the next one, so the run is the least the boat sailed. The site writes such a run ≥. It can be a record, and it counts in averages and medians unless it began late.

The run divided by its hours: average speed over the ground.

The fall in distance to finish over the 24 hours. This is what YB’s own 24-hour column shows.

The same as a speed.

Average speed on the first 4-hour leg of the 24 hours (the oldest). Blank: no fix at one end.

Second leg.

Third leg.

Fourth leg.

Fifth leg.

Sixth leg (the newest).

Miles gained (+) or lost (−) on the leader in 24 hours, fix to fix.

The 24-hour run minus the median run of the boats within 150 nm, which sail much the same weather. Blank when the boat’s own 24 hours began late.

How many boats that median is made of. Under 2, the column before is blank.

Distance from the boat to the nearest point of the track the leader sailed.

The side of that track she lies on.

Miles sailed over the last 42 legs. A restarted boat counts from her restart.

Average speed over those legs.

Speed made good toward the finish over 7 days; it drives the ETAs.

TRUE when the tracker missed a report in the seven days of the run: the 7-day run is then the least the boat sailed, and the site writes it ≥.

The sum of all 4-hour legs since the start (or the restart).

The fall in distance to finish since the start (or the restart).

The boat’s longest 24-hour run so far. Where the tracker missed a report in its window it is the least the boat sailed: see best_24h_run_reports_missed.

The report that closed it.

The boat’s fastest 4-hour leg so far.

The boat’s longest 7-day run so far. Where the tracker missed a report in its window it is the least the boat sailed: see best_7d_run_reports_missed.

TRUE when this 24-hour run is the boat’s longest so far.

TRUE when it is also the longest of the whole fleet so far.

Reports the tracker missed in the window of the best 24-hour run. 0: every report was there. Above 0: the best is the least the boat sailed, and the site writes it ≥.

The same for the best 7-day run.

Miles ahead (+) or behind (−) where Van Den Heede, the 2018 winner, was on the same race day.

The same against Neuschäfer, the 2022 winner.

Average leg speed divided by model wind speed, over legs sailed in 8–25 kt since the start. Needs ten legs.

How many legs that ratio is made of.

The spread (standard deviation) of 4-hour leg speeds over 7 days. Lower is steadier.

The share of legs at 5 kt or more over 7 days.

Hours on legs under 2 kt over 7 days.

Average leg speed at night (20:00–06:00 local solar time) minus by day, since the start. Needs six legs of each.

The first mark of the course (NOR C.1.3) the boat has not yet passed.

Great-circle distance to it.

Distance to the mark divided by the 7-day made-good speed.

When a restarted boat left again (NOR C.1.2). Her runs and speeds count from then.

MODEL wind at the fix (Open-Meteo, hourly mean at 10 m). Not measured on board.

Model gust.

The direction the model wind blows from.

Model sea-level pressure.

Model significant wave height, sea and swell combined.

Model swell height.

Model swell period.

Model current speed.

The direction the model current sets toward.

Model sea-surface temperature.

The mean of the model wind at the reports of the 24 hours that have a value.

The highest of them.

How many of the six reports have a model value. The weather service does not always answer.
