Explore the relationship between boat speed, wind and angle.
Uses selected boats and time window, independently of the wind filter. Dashed lines bridge gaps longer than 20 min. Progress is the publisher’s comparison with its previous record, which may precede the previous captured point. Times shown in UTC.

Uses selected boats and the time window, independently of the wind filter. Missing readings stay blank; a dashed line bridges missing readings or gaps longer than 20 min. Hover a point for its value, or click to inspect the source.
Normalised value = boat speed ÷ forecast wind speed for each sample, then averaged within each 5° bin. 1× means boat speed equals wind speed; 2× means twice the wind speed. Zero or missing wind readings are excluded.
0° upwind · 90° across the wind · 180° downwind. Uses the smallest angle between the published boat course and wind-from direction. Empty bins stay blank; lines join adjacent populated bins only. Uses the selected boats and current wind / time filters.
