Sailing performance analysis for a One Off from 1982, built by and designed by Evind Amble.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 12/05/2026
This one-off cruiser-racer strikes a balance between comfort and performance. It achieves 5.5 knots upwind in 10 knots of wind, and its symmetric spinnaker supports solid downwind speeds, reaching 5.2 knots in the same conditions. The boat shows planing potential with a top speed of 8.9 knots in 20 knots of wind. Its sail wardrobe is well-balanced, with a symmetric spinnaker and a jib proportionate to the mainsail.
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.
