Zigomar - NOR79
Sailing performance analysis for a PLATU 25 OD (series year 1997), built by Beneteau and designed by FARR.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 29/06/2026
Designed for pure racing, this boat excels with its speed and agility. It reaches 5.8 knots upwind in 10 knots of wind, reflecting its strong upwind performance. Downwind, it performs well too, with a symmetric spinnaker boosting its speed to 5.8 knots in similar conditions. The compact jib relative to the mainsail ensures efficiency and balance as it navigates the course.
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.
