Speeds are in knots; bearings are true. Boat speed (SOG) and course (COG) are estimated between recorded fixes. Relative angles are measured from the boat’s course toward port or starboard. Apparent wind uses the modeled wind and boat motion. Boat-dependent values are unavailable after the last fix.

Arrows point downwind; longer arrows mean stronger wind. The orange line is Maverick’s recorded track. The dot interpolates between archived positions.

Wind is the historical analysis nearest each moment. It shows modeled conditions, not onboard measurements or the forecast the crew saw.
