Sailing performance analysis for a Arcona 400 from 2003, built by Boo Marin AB and designed by Stefan Qviberg.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 04/03/2026
A versatile cruiser-racer that excels in various conditions, reaching 7.8 knots on a reach in 14 knots of wind. It performs admirably upwind, achieving 6.4 knots in 10 knots of breeze. Downwind, the large symmetric spinnaker aids performance, hitting 5.7 knots in the same wind. The balanced sail plan with its well-proportioned sails ensures a stable and enjoyable sailing experience.
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.
