Brutus - NED8517
Sailing performance analysis for a Platu 25 Mod (series year 1995), built by beneteau and designed by Farr.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 08/05/2025
A versatile cruiser-racer, this boat reaches 6.8 knots on a reach in 10 knots of wind, demonstrating solid performance for its class. It has planing potential, with speeds up to 10.3 knots in 20 knots of wind, making it exciting in strong conditions. The boat is equipped with a modest asymmetric spinnaker, which provides decent downwind performance, reaching 5.1 knots in 10 knots of wind. Its jib is compact compared to the mainsail, optimizing upwind capability.
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.
Measured sails
Spinnaker measurements were not supported before this season's certificates. If no spinnaker is shown, that's why.
