Farrgo - SWE10077
Sailing performance analysis for a Farr 30 from 1999, built by Ovington and designed by Farr.
Data provided by the Offshore Racing Congress (ORC)
A pure racer that excels with its strong upwind and fast downwind performance. It achieves 6.3 knots upwind in 10 knots of wind and can reach up to 9.9 knots when reaching in 14 knots of wind. The large symmetric spinnaker enhances its downwind capabilities, making it quick for its size. The jib is compact compared to the mainsail, designed to maximize its upwind efficiency.
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.
