Uro - NOR5887
Sailing performance analysis for a MAMBA 341 from 1983, built by Mamba Boats AB and designed by MAGNUSSONROLF.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 10/08/2026
A reliable comfort cruiser, perfect for those who prioritize ease and stability over speed. It comfortably reaches 6.8 knots on a reach in 10 knots of wind, providing a steady and enjoyable sail. The boat is equipped with an asymmetric spinnaker, yet its downwind performance is modest, achieving 5.04 knots in the same wind conditions. The sail plan is balanced, with a modest jib and mainsail setup.
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.
