Yme - NOR71
Sailing performance analysis for a Yngling from 1970, built by Borge Bringsværd and designed by Jan Herman Linge.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 14/04/2026
This comfort cruiser makes steady progress, achieving 4.5 knots upwind in 10 knots of wind. Although it struggles to match upwind speed with faster peers, it shows potential for planing with a top speed of 7.85 knots in 20 knots of wind. Downwind performance is modest, partly due to its small symmetric spinnaker. The jib is compact relative to the mainsail, providing a balanced sail plan that's easy to handle.
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.
