Sailing performance analysis for a Dufour 425 from 2007, built by Dufour Yachts and designed by UmbertoFelci.
Data provided by the Offshore Racing Congress (ORC)
The Dufour 425 is a well-rounded cruiser-racer that comes alive in heavy winds, achieving a top speed of 10.52 knots in 20 knots of wind. It performs strongly upwind, reaching 6.74 knots in 10 knots of breeze, and maintains solid performance on a reach with 8.07 knots in 14 knots of wind. Equipped with a large genoa relative to its mainsail and an asymmetric spinnaker, it offers a balanced sail wardrobe for versatile sailing conditions.
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.
