Rocky Ocean - NOR11782
Sailing performance analysis for a one off from 2005, built by H. Aaslestad and designed by H. Aaslestad.
Data provided by the Offshore Racing Congress (ORC)
This cruiser-racer is quick for its size, achieving 6.34 knots upwind in 10 knots of wind. The large symmetric spinnaker provides power downwind, reaching 5.96 knots in the same wind conditions. With a large genoa relative to the mainsail, it excels at harnessing wind power efficiently. It's heavy for its length, which contributes to its strong upwind performance.
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.
