Sailing performance analysis for a Elan 37 from 2004, built by Elan Marine and designed by Rob Humphery.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 25/08/2026
This comfort cruiser performs admirably with a balanced sail plan and a large symmetric spinnaker, ideal for those seeking a mix of speed and ease on the water. It reaches 6.1 knots upwind in 10 knots of wind and achieves a comfortable 7.5 knots on a reach in the same conditions. In stronger winds of 20 knots, it can hit a top speed of 9.3 knots, demonstrating its capability in varied 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.
