A screen shot from the FREE NavmonPC PC sailing software. This Program also features a nice AIS interface. This is 12 hour snapshot showing our sailing speed vs wind speed. We're in cruising mode here, not racing. Running on Autopilot and primarily utilizing the 'set it and forget it' method of sail trim. 12 hours from 2:30AM to 2:30PM.
True Wind Speed (TWS) 7.4 knots
Speed Over Water (SOW) 7.3 knots.
LightSpeed glides along effortlessly in these conditons.
