Eos - NOR12058
Sailing performance analysis for a Sun Od 42i from 2007, built by Jeanneau and designed by Marc Lombard.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 06/05/2026
This comfort cruiser is built for leisurely sailing with a focus on ease rather than speed. It reaches 6.2 knots upwind in 10 knots of wind, and picks up to 10.26 knots in strong winds of 20 knots. The boat features a balanced sail plan with a compact jib relative to the mainsail, and carries a modestly sized asymmetric spinnaker for downwind sailing. While it's not the fastest downwind, its performance improves significantly in heavier conditions.
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.
