Tracks by leg
GPS tracker tracks (bow offset is a few metres and omitted at this scale). Legs split at each boat's closest approach to the mark trackers. Tap a boat or a table row to highlight it.

DTL (Vakaros): the boat's own device figure from the feed, bow-corrected; the primary number. Check: our estimate from the GPS track (bow offset along heading, at the device's start fix ~0.9 s before the gun). Late: DTL ÷ speed toward the line. Line pos: 0% pin, 100% RC.
TWA / VMG are estimates. The boats carry no wind sensor; wind direction comes from the fleet's steady upwind tack headings (cross-checked against a weather model). VMG = distance made good along the wind ÷ leg time. Leg TWA = median |TWA| while sailing steadily. ▲ best / ▼ worst in column.
