Sailing performance analysis for a ONE OFF/SPISSGATTE from 1991, built by Kais Båtbyggeri and designed by .
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 28/04/2026
This motorsailer is built for comfort rather than speed, with a balanced sail plan that includes a symmetric spinnaker. Though it reaches 5.0 knots upwind in 10 knots of wind, it's not known for its upwind performance. Downwind, it manages 4.6 knots in the same conditions, but doesn't excel here either. The boat is modestly canvassed for its size, which contributes to its steady but unhurried sailing style.
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.
