Amante - NOR7871
Sailing performance analysis for a MØREBAS 33 (series year 1983), built by Mørebas and designed by .
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 03/06/2026
This is a motorsailer with a focus on comfort and versatility rather than speed. It reaches 5.2 knots upwind in 10 knots of wind, but isn't built for fast performance, especially downwind where it manages 4.6 knots. The boat carries a modestly sized asymmetric spinnaker, and its large genoa dominates the sail plan, which is conservative 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.
