Coquette IV - SWE434
Sailing performance analysis for a XP-33 from 2013, built by X-yachts and designed by Jeppesen.
Data provided by the Offshore Racing Congress (ORC)
This performance sailboat stands out with its impressive speeds, achieving 6.4 knots upwind in 10 knots of wind and 6.2 knots downwind under the same conditions. The boat excels on a reach, clocking 7.8 knots in fresh winds of 14 knots. Its balanced sail plan features a large symmetric spinnaker, enhancing its strong downwind capabilities. Designed for those who appreciate speed and agility, this vessel is quick for its size and performs exceptionally well in a variety of wind 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.
