Daddys Lil Monster - NOR10378
Sailing performance analysis for a JS9000 from 2002, built by Admirality and designed by Swarbrick.
Data provided by the Offshore Racing Congress (ORC)
A pure racer designed for speed, this boat excels downwind with an impressive 6.25 knots in 10 knots of wind. It reaches 8.24 knots on a reach under the same conditions, showing its agile performance. The asymmetric spinnaker is modest for its size, but complements the compact jib well. Built light and well-powered, it's quick for its size and thrives in racing environments.
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.
