Orca - NOR13948
Sailing performance analysis for a MD 35 from 2007, built by MD Boats and designed by MarkMills.
Data provided by the Offshore Racing Congress (ORC)
This pure racer, designed by Mark Mills and built by MD Boats, excels with its strong performance across various conditions. It achieves an impressive 6.7 knots upwind in 10 knots of wind and can reach speeds up to 15.05 knots in strong winds. The sail wardrobe includes a well-sized asymmetric spinnaker that complements its balanced sail plan, making it fast downwind as well. With its light build and good power-to-weight ratio, it's quick for its size and strong 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.
