Shiba Juvel - NOR16053
Sailing performance analysis for a Dehler 46 from 2015, built by Dehlerhler Segelya and designed by Judel -Vrolijk.
Data provided by the Offshore Racing Congress (ORC)
The Dehler 46 is a performance sailboat that excels in upwind conditions, reaching 7.3 knots in 10 knots of wind. Even without a spinnaker, it achieves a respectable downwind speed of 6.6 knots in the same wind. It reaches speeds up to 9.1 knots when sailing across the wind in 10 knots of breeze. The balanced sail plan features a compact jib relative to the mainsail, designed for optimal performance upwind.
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.
