Leigas - NOR16190
Sailing performance analysis for a RM970 from 2017, built by Fora-Marine and designed by Marc Lombard.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 23/05/2025
The RM970 is a performance sailboat that truly comes alive in a breeze, reaching up to 8.5 knots in 14 knots of wind. Designed for speed, it shows planing potential with its balanced and well-powered sail plan, especially on a reach. The large asymmetric spinnaker enhances its downwind performance, making it capable of 5.5 knots in 10 knots of wind. The jib is nicely proportioned to the mainsail, ensuring versatility across conditions.
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.
