Sutalaus - NOR16070
Sailing performance analysis for a International 806 from 1978, built by Monark and designed by Pelle Petterson.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 21/04/2026
This cruiser-racer offers a balanced sailing experience, with a sail plan that includes a symmetric spinnaker. It achieves 5.2 knots upwind in 10 knots of wind, showing its solid performance on a beat. Downwind, it struggles a bit, reaching 4.7 knots in the same 10 knots of wind, where the spinnaker doesn't quite keep pace with its peers. The jib is nicely proportioned relative to the mainsail, optimizing 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.
