Semper Fi - NOR14860
Sailing performance analysis for a Sun OD 439 from 2012, built by Jeanneau and designed by Philippe Briand.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 12/06/2025
The Sun OD 439 is crafted as a comfort cruiser, prioritizing ease and leisure over raw speed. It achieves a steady 6.34 knots upwind in 10 knots of wind, but its performance is more restrained downwind, managing 5.63 knots in the same conditions. The boat is modestly canvassed for its size, featuring a balanced sail plan with an asymmetric spinnaker and a jib that complements the mainsail effectively.
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.
