Hei-Tiki - NOR10823
Sailing performance analysis for a Sun Fast 37 from 2004, built by Jeanneau and designed by Jacques Fauroux.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 15/05/2026
Designed as a comfort cruiser, this boat offers a smooth ride with a balanced sail plan. It reaches 6.1 knots upwind in 10 knots of wind, ensuring reliable performance on various points of sail. Downwind, it achieves 5.2 knots in 10 knots of wind, aided by its asymmetric spinnaker. While it may not be the fastest in its class, the heavy build adds stability and comfort for leisurely cruises.
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.
