Luna - NOR15980
Sailing performance analysis for a Sun OD 409 (series year 2011), built by Jeanneau and designed by Briand.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 28/03/2025
This comfort cruiser is designed for relaxed sailing rather than racing. With a balanced sail plan and a modestly sized asymmetric spinnaker, Luna achieves 6.1 knots upwind in 10 knots of wind. Its downwind performance is less competitive, reaching 5.5 knots in similar conditions. The jib is compact relative to the mainsail, supporting a comfortable and steady cruising experience.
Sailing performance as a polar diagram
A polar diagram shows boat speed at different wind angles and wind speeds. The distance from center represents boat speed in knots, and the angle represents the boats angle to the wind. The wind speed is shown as true wind speed (TWS), not apparent wind speed. Likewise, the wind angle is shown as true wind angle (TWA), not apparent wind angle.
Beat: Sailing upwind (toward the wind)
Beam Reach: Sailing across the wind
Run: Sailing downwind (away from the wind)
VMG Performance
Wind Speed (columns): True wind speed (TWS) in knots - the actual wind speed, not the apparent wind you feel on deck.
VMG (Velocity Made Good) is your effective speed toward your destination, not your actual boat speed.
Beat VMG (top bars): Speed made good when sailing upwind. Higher is better - it means you're reaching the windward mark faster.
Run VMG (bottom bars): Speed made good when sailing downwind. Higher is better - it means you're reaching the leeward mark faster.
Measured sails
Spinnaker measurements were not supported before this season's certificates. If no spinnaker is shown, that's why.
