Sailing performance analysis for a 11 Metre (series year 1991), built by and designed by Holland.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 28/04/2026
This performance sailboat is well-powered for its size, showing strong speeds across various wind conditions. It reaches 6 knots upwind in 10 knots of wind and can accelerate to 11.76 knots when the breeze picks up to 20 knots. The boat features a symmetric spinnaker and a compact jib relative to the mainsail, enhancing its versatility on different points of sail. Its lightweight build and planing potential make it an exciting choice for competitive sailors.
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.
