Havsule - NOR12061
Sailing performance analysis for a Grand Soleil 37 BC (series year 2005), built by Grand Soleil and designed by CARKEEK/BOTIN.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 13/05/2025
A well-balanced cruiser-racer that excels in a variety of conditions. Reaching a solid 7.6 knots on a reach in 10 knots of wind, it's built for versatile performance. The large symmetric spinnaker enhances its downwind capabilities, making it competitive in fresher conditions. The sail plan is balanced, providing good upwind performance with a speed of 6.3 knots in 10 knots of wind.
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.
