Sailing performance analysis for a DEHLER 35 CWS from 1995, built by Dehler and designed by VANDESTADT.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 29/04/2026
Balder is a comfort cruiser that prioritizes a smooth sailing experience over raw speed. It reaches 5.8 knots upwind in 10 knots of wind and can hit 8.7 knots in stronger conditions at 20 knots of wind. Although it struggles a bit downwind with a speed of 5.1 knots, the balanced sail plan with a moderately sized symmetric spinnaker ensures stability and ease. The jib is well-proportioned compared to the mainsail, offering reliable performance on various points of sail.
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.
