Sweet Jane - NOR13974
Sailing performance analysis for a J-80 OD from 1998, built by J Composite and designed by JOHNSTONE.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 20/05/2026
A performance sailboat, this model is light for its length and showcases planing potential. It can reach 5.6 knots upwind in 10 knots of wind and 6.96 knots on a reach. With a large asymmetric spinnaker, it's equipped for robust downwind performance, achieving 10.98 knots in strong winds. The jib is compact relative to the mainsail, supporting its upwind capabilities.
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.
