RS Aero 9

A polar diagram shows how fast a RS Aero 9 typically sails at each angle to the wind, giving you target speeds to steer to. This one is built from GPS tracks recorded by the SailingMetrics community sailing a RS Aero 9 — the more tracks, the more accurate it gets.

Target boat speed by angle to the wind (0° = head to wind, 180° = dead downwind), one curve per wind strength -- lighter blue for light wind, darker blue for stronger wind. Click a wind-speed entry in the chart's legend to isolate that curve. Pooled from 4 community sailing sessions on this boat, last updated August 12, 2026.
