HAV AV TID - NOR16006
Sailing performance analysis for a Oceanis 38.1 from 2018, built by Beneteau and designed by Finot.
Data provided by the Offshore Racing Congress (ORC)
The Oceanis 38.1 is a versatile cruiser-racer that excels with a strong upwind performance, achieving 6.8 knots in 10 knots of wind. It reaches 8.7 knots in fresh conditions, showcasing its ability to come alive in heavier air. The boat's sail wardrobe lacks a spinnaker, which affects its downwind performance, making it more suited for upwind and reaching courses. The balanced sail plan features a compact jib relative to the mainsail, modestly canvassed for its size.
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.
