Screen capture from our B&G Zeus 12 navigation system, showing a screen John requested to keep easy track of our progress. DESTination is Kinsale, Ireland; DTD is Distance to Destination in nautical miles. DSTWTR is the distance through the water we have advanced since we left Fort Lauderdale, not necessarily in a straight line.
SOG, or current Speed Over Ground, is expressed in knots, and is equivalent to 12.4 kms/h; yes, it is slow going in a sailboat!
