Helen - NOR10763
Sailing performance analysis for a Sun Fast 37 from 2004, built by Jeanneau and designed by Jacques Fauroux.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 01/09/2025
This boat is built for comfort rather than speed, fitting its motorsailer category with ease. It reaches 5.7 knots upwind in 10 knots of wind, and 5.2 knots downwind in the same conditions. With a symmetric spinnaker that struggles to keep up with peers, it's not the fastest downwind performer. The jib is compact compared to the mainsail, emphasizing its focus on balanced cruising rather than racing efficiency.
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.
Measured sails
Spinnaker measurements were not supported before this season's certificates. If no spinnaker is shown, that's why.
