Breezin - SH12510
Sailing performance analysis for a X-40 (DK) from 2004, built by X-Yachts and designed by Niels Jeppesen.
Data provided by the Offshore Racing Congress (ORC)
This performance sailboat shows impressive downwind capabilities, reaching 6.37 knots in 10 knots of wind. It holds its own upwind as well, achieving 6.43 knots in the same conditions. The large symmetric spinnaker enhances its speed on a run, while the balanced sail plan provides an overall agile and responsive sailing experience. With a light build for its length, it's designed for those who enjoy a fast and spirited ride.
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.
