Sana - NOR13372
Sailing performance analysis for a First 31.7 from 2008, built by Beneteau and designed by Groupe Finot.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 30/04/2026
This cruiser-racer offers a balanced sailing experience with a symmetric spinnaker to assist downwind. It reaches 5.7 knots upwind in 10 knots of wind, showing solid performance on a beat. However, downwind speeds like 5 knots in the same conditions point to room for improvement against faster competitors. The sail plan is well-balanced, with no extremes in jib or mainsail size.
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.
