Lun - NOR9310
Sailing performance analysis for a N-YACHTS 41 (series year 1998), built by and designed by Peter Norlin.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 11/08/2025
A well-rounded cruiser-racer delivering solid performance across various conditions. This boat reaches 6.6 knots upwind in 10 knots of wind, featuring a balanced sail plan with a compact jib relative to the mainsail. Downwind, it makes good use of its asymmetric spinnaker, achieving 5.7 knots in 10 knots of wind. Top speeds reach 8.5 knots in 14 knots of wind, showing strong capability in fresher breezes.
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.
