BLUE - NOR1
Sailing performance analysis for a H-boat from 1967, built by and designed by Hans Groop.
Data provided by the Offshore Racing Congress (ORC)
A well-rounded cruiser-racer, this boat reaches a respectable 6.5 knots on a reach in 10 knots of wind. Upwind, it sails efficiently at 5.2 knots in the same wind, making it a reliable performer in varied conditions. While the downwind speed is moderate, the symmetric spinnaker is modest for its size, which might limit performance compared to larger competitors. The compact jib balances well with the mainsail, optimizing upwind capabilities.
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.
