Poniente - NOR15651
Sailing performance analysis for a Sun Od 479 from 2016, built by Jeanneau and designed by Philippe Briand.
Data provided by the Offshore Racing Congress (ORC)
This performance sailboat shines with its balanced sail plan and light hull for its length. It achieves a commendable 7.1 knots upwind in 10 knots of wind and can reach speeds of 8.7 knots on a reach in the same conditions. Downwind, it utilizes a modest asymmetric spinnaker, which complements its overall sail wardrobe. A solid choice for sailors seeking a blend of speed and handling.
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.
