Sailing performance analysis for a First 31.7 LR from 1998, built by Beneteau and designed by Groupe Finot.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 29/04/2026
This comfort cruiser offers a balanced sail plan, featuring a compact jib and a symmetric spinnaker. While it's not an upwind flyer, the boat can reach 5.6 knots upwind in 10 knots of wind and performs steadily on a reach with 6.9 knots in the same conditions. Downwind performance is modest, achieving 5.1 knots in 10 knots of wind, but it remains a reliable and comfortable choice for relaxed cruising.
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.
