Sailing performance analysis for a Grand Soleil 37 B& from 2006, built by Cantiere del Pardo and designed by Botin&Careek.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 29/04/2026
This comfort cruiser offers a smooth sailing experience with a balanced sail plan. It reaches 6.2 knots upwind in 10 knots of wind and can achieve a top speed of 9.1 knots in strong winds. Downwind performance is modest with a symmetric spinnaker, making it less competitive against faster peers. The jib is well-proportioned to the mainsail, supporting a well-rounded upwind performance.
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.
