Tacking
During the upwind legs, 3 tacks were analysed.
Tack angle
The tack angle is the change in heading through a tack — the angle between the course sailed before and after the manoeuvre. A smaller angle means a tighter, more efficient tack that keeps the boat closer to the wind, while a larger angle indicates more heading was lost during the turn. The box shows the middle 50 % of tacks (Q1–Q3), the line marks the median, and the thin bar spans the full range. Comparing starboard-to-port and port-to-starboard can reveal whether tacking is consistently better on one gybe.
