Totto - NOR27
Sailing performance analysis for a 707 from 1980, built by egen and designed by Gösta Edwardsson.
Data provided by the Offshore Racing Congress (ORC) · Certificate issued 21/04/2026
This light cruiser-racer makes a solid 5.2 knots upwind in 10 knots of wind and shows planing potential with top speeds reaching 8.77 knots in strong conditions. While it isn't the fastest downwind, partly due to its modest symmetric spinnaker, it performs well on a reach with speeds of 6.2 knots in 10 knots of wind. The sail plan is balanced, with a jib that complements the mainsail effectively.
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.
