Dollard IV - NOR10039
Sailing performance analysis for a DEHLER 39 JV from 1998, built by Dehler Yachtbau and designed by Judel -Vrolijk.
Data provided by the Offshore Racing Congress (ORC)
This cruiser-racer combines speed and balance with a well-proportioned sail plan. Achieving 6.7 knots upwind in 10 knots of wind and reaching 7.98 knots on a reach, it excels in versatile conditions. The symmetric spinnaker complements its strong downwind performance, making it especially quick for its size. Despite being on the heavier side for its length, it maintains impressive speed across 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.
